In the field I work in, if someone says "Pelican", 99.99% of the time it's going to be an equipment case. We never have reason or need to refer to the actual bird.
You can always ask them to draw something else, as a way to avoid any possible pelican related data contamination; given how popular the pelican test is, I'm sure there's some pelican SVG drawing in the training sets of at least some of these models by now. For instance, you could ask for an SVG drawing of a cyborg bear riding a rocket powered unicycle.
It's a silly fun little benchmark, and because Simon's been doing it for so long, you have a lot of examples over the years to compare. But you can always come up with and run your own test with other drawings.
"How many pelican riding bicycle SVGs were there before this test existed? What if the training data is being polluted with all these wonky results..."
In regards to your post and the 16k reasoning output.
Try setting reasoning levels yourself manually. We see in the benchmarks that one of the graphs shows low, mid, max, so its clearly there.
I had the same issue with GLM 5.2 only offering high/max.
By playing around with openai compatible protocol, and setting the reasoning level from none, low ... high, xhigh and testing a flawed logic test.
It was easy to see that GLM had all the different reasoning levels. Low was like one line, medium did a few, high started to really expand, xhigh was a page or 2, max was MAX.
Very sure that you can force K3 into using less reasoning.

Love how passive aggressive "something I can actually help you with" is!
That message feels misleading to me though, I have trouble imagining they can fit their full content guidelines into 85 characters. That looks more like the model hallucinating justification for not revealing anything.
I tried asking it "what time is it?" and got back:
> I don't have access to real-time information, so I can't tell you the current time. Your device's clock (on your phone, computer, or watch) will show you the accurate time for your location.
I think that's probably a good thing. Sycophancy seems to be correlated with AI psychosis. GPT 4o was creepy sycophantic and has a body count. It'll be good for chatbots to be more interested in facts than in agreeing. (Then again, I found Qwen 3.6 to be strident in its lies about Uyghurs in China, among other "sensitive" topics, parroting the party line and getting almost hostile when told to search the web for current information.)
So Chinese labs are driving essentially towards commodotized intelligence. Even if its a few months behind the US.
Is this a classic 'commoditize my compliment' situation? They want to sell the hardware and infrastructure behind AI and make the software part not the value driver / moat?
I can see it. But also even two Chinese labs sinking 100s of millions USD into training isn't exactly commoditization. It's still a ton of effort with dubious payoff.
If there was some grand strategy for all Chinese labs, surely it'd have leaked by now. I think its more likely that:
- Companies can still make money from commodities
- Chinese labs only have 5-10% the valuation of OpenAI/Anthropic, so massive monopoly profits aren't necessary. Profit expectations for tech companies in China are really low in general, complete opposite of the US.
- Open weighting is a great way to get talent/attention/reputation
There is definitely strategy and direction coming from the top. CEOs have been summoned for conversations. There are new rules like no Ai lovers that certainly show they are thinking about things.
The AI CTO from The Linux Foundation, Matt White, spoke about his recent trip to talk to the Chinese Ai labs ~month ago.
This is strategy by Chinese government, so much of US economy is invested in AI. Releasing free or cheap versions of the models undermines US economic growth. It’s asymmetric strategy that makes sense if you are close second in AI race. If situation is reversed, US would do the same.
It's the same reason Meta open sourced Llama and AMD open sourced FSR. When you're behind it is a prudent strategy because it undermines investment in the private frontier. Once you're on top you pull the rug and go closed source. There are no morals in this anywhere to be found.

That is utter peanuts given the stakes. This is competition between two super powers for the most important technology in human history.
A more charitable reading of this comment is that you can make a game theoretical argument for these behaviors that doesn’t require altruism. And that argument therefore doesn’t preclude going closed at a later date.
Google on it's own is spending 1000x that in a single year $280B in '26 alone iirc
I could also argue with GP's comment that some US companies are driving towards commoditization as well. One released a model this week and another announced their series d today.
So far it rates "quite important" and certainly not "paradigm shift".
I've just spent most of the day wading through vibed blogs and what not to glean info on ... setting up LLMs! The content on the web is already in a parlous state and rapidly getting nicely but rather the same presentation and mostly right but somewhat wrong, often in crucial parts.
On the bright side I did find an absolute belter of a vibed site and it was only mildly wrong but I was able to sort that bit out and to be fair I think it was written up by an expert with help from a LLM and had a genuine human mistak in it.
Anyway, I suggest you might like to look at the internet as a whole as a paradigm shift and reserve judgement on LLMs and this decade's version of AI.
Whatever you want to attribute it to, the Chinese labs would get zero attention if it weren't for their models being downloadable, so it's a marketing play. You can't run their largest models on consumer hardware, it needs a hosted service/professionagrade equipment. Which means using their service becomes an option, especially at their pricing. So that's the play.
Frontier labs release frontier models to the public only if there is market pressure to do so. Anthropic is not even hiding that they have been using Mythos internally for months now.
I wouldn’t be surprised if OpenAI (so much for “open”) is using GPT-6 internally already.
It appears that peasants like us are not going to get access to frontier AI anymore at any price.
Granted I've only used it for a few hours, but to me K3 still appears below Sonnet, even below 4.5.
I have their highest subscription, so it's not that I can't find uses for it and it has sides to it I really like, and it performs really well in some situations, but 2.7 also gets totally lost on tasks Sonnet and Opus has no problems with, and it looks like that is still the case with K3.
That said, I'm doing things with these models that are a lot more complex than the average app people will throw these models at, so I'm sure there are lots of use cases where it will perform better than what I'm seeing.
That assumes progress is linear, which it certainly is not. We’re also assuming Chinese companies are releasing their best stuff when our own government is dictating what American companies can and cannot release.
I don’t know for sure that they are weeks or months behind. I doubt anyone outside of 3 letter agencies knows that. The pace of AI is crazy fast and China is notoriously secretive. We could be comfortably ahead or China could have the top model by the end of the year.
I don’t think any of us have enough information to know what’s really going on, but I suspect it’s a very tight race.
Mythos/Fable release was significantly delayed because Dario is pushing for regulatory capture.
It also plays into the hype because there was no one else releasing a model better than Opus. The same thing was with the scarcity crap. They said Fable will not run on subscription, then they will run just for a little while and then forever... Once you get the game they are playing it starts to become quite laughable. If you check his history he was doing the safety/terminator stuff since the days at OpenAI when the models couldnt even calculate 1+1 reliably
All three models were quite likely undergoing training at the same time, with Ant a couple of months ahead. Glasswing was announced 3 months ago, Sol and Kimi were already being trained at that point. They are taking snapshots and doing experiments the whole way through anyway and all models will continue to be trained after release. Kimi 3.1 could be better than Fable 5.1
Nah that’s not how that works. There are literally an endless stream of examples of the model providers tweaking backend stuff and improving prompt responses without using new or retrained data. And even if they added new training data to an existing model, it isn’t true to say that model ‘just came out’. But even then, when providers release better models based on new training data they release it as a new dot version, which boosts their sales from the announcement.
Fable has been out for more than a month - I didn’t have the preview version and I was using it around June 10th, when my Claude subscription expired. Saying “Fable only really came out 2 weeks ago” is just factually incorrect all around.

The US is a barrier to a number of key Chinese goals, like reunification with Taiwan. So of course most of what they do will take the US into consideration.
China sanctioned and voted for UN resolutions to sanction Iran in the past. Then Trump baselessly abandoned the JCPOA. Even the US own DNI said it is the consensus of all 18 intelligence agencies that Iran was in compliance and not seeking nuclear weapons. China, correctly, called the renewed sanctions illegal and refused to follow them
I took advantage of their "Token Cup" for the world cup and won 530,000 credits. I believe at the time they said it had to be used in the desktop app, which I have installed. Nowhere can I find any sort of balance or evidence of the 530k other than the Token Cup page itself that say that is what I was given.
Their web chat has almost no settings of customization. Everything they present just comes off as amateurish to me. I trust them less than most Chinese AI companies, which a very low bar.
1M context, pricing is $3/$15 for 1M tokens (cache $0.3), which is extremely high for a Chinese open-weight model, but if it's truly competitive with most of the current frontier and is only behind Fable/Sol, the pricing is justified.
This is 1:1 pricing of Anthropic's Sonnet series (except Sonnet 5 which is currently on discount), and very close to 5.6 Terra pricing (Terra's input is $2.5).
One thing to consider, though: reasoning efficiency matters directly for how expensive a model actually is in real use. GPT's models are extremely reasoning efficient, and some Claude models like Fable at lower effort are as well. So if Sol spends 10K reasoning tokens to do something (at $30/1M) vs Kimi K3 that spends 50K reasoning tokens, Sol would win on cost effectiveness.
It also depends on how many tokens it needs to burn through to accomplish something.
At this point, I always look at things like Artificial Analysis' total cost to run their tests. It'll take into consideration the cost of tokens, how many tokens it burns through, and how effectively it uses caching (and the price of that caching).
If a model "costs the same" but its reasoning ends up going through a ton more tokens, it doesn't really cost the same in real world usage.
Tokenizers define the alphabet on which the language model is trained. I don't want people to get the impression it's a module which can be swapped out or modified on its own. Alphabet size is a design consideration related to correctly encoding the training data.
That's true, but it makes it difficult to compare pricing when it's based on tokens. Maybe we need a benchmark for price per a specific input, like enwiki8.
Yes, almost all work people share which seeks to measure the capabilities and differences of models needs to get more precise. We are clamoring to say something meaningful about these things.
But even that isn't the whole story because the models can produce wildly amount of thinking output as well as regular output for a similar query. Sometimes you can take a cheap model and have it think a ton or an expensive model that thinks little and get similar results. But the number of tokens generated will be wildly different.
A better metric is price per byte. Most thinking traces, prompts, skills are in plain English, which is roughly 1 byte per character, assuming UTF-8 encoding (even code should not be much more either). As an aside, it is common to use bits-per-byte as a loss metric instead of the per token calculation, precisely because of the effect of different tokenizers.
It's going to vary dramatically based on which text you put in. Really it's hard to make one benchmark number that's relevant to all cases. But maybe we can make something a little more specific, like regular English text, code, the model's own thinking tokens, image inputs etc.
It is kind of a shame we ended up comparing token pricing across models and providers when it doesn’t really make sense. Not sure what would be better though.
I’ve been struggling to understand the reason for the newer apparently less efficient Anthropic token encoding. If all inputs are less efficient in this encoding, why does it exist? Has Anthropic released any information that would convincingly show it was anything other than a stealth price hike? Please don’t respond if you are speculating.
I doubt you are going to get a response from an anthropic employee, but I think it is safe to assume they have swapped to a new tokenizer because it improves the performance of their models.
> That said, Kimi is competing against GLM in my mind, and GLM 5.2 is less than 1/3 the price.
Having used GLM 5.2 extensively and K3 for a few hours now, these models are nowhere near each other. 5.2 is a great model, and I use it for a lot of things, but it's noticeably below Opus 4.8 or GPT-5.5 in real-world usage.
GLM is actually quite expensive in actual practice because it's not very token efficient. I've yet to find a way to run it on a monthly sub reliably for cheaper than Codex.
Neuralwatt was cheap (but slow) but they cranked their price.
Ollama monthly sub is speedy but doesn't offer a lot of quota.
Right now unless you're paying by the token, there's no cost based reason to use the open weight models for daily coding work because the monthly coding plans from Anthropic and OpenAI are a better deal.
> I've yet to find a way to run it on a monthly sub reliably for cheaper than Codex.
Matches my experience, I got their Pro subscription and while I enjoyed the model itself a lot and while their ZCode harness is also pretty nice, it gave me less tokens for similar amounts of money that Anthropic would give me on a subscription: https://blog.kronis.dev/blog/z-ai-s-glm-5-2-is-a-great-model...
I'm yet to try out Kimi, but if their subscription were to be anywhere comparable to Anthropic/OpenAI, I might just switch over because competition is good.
DeepSeek V4 Pro is really affordable per-token but regularly kept making mistakes in the tasks I gave it. I mean I could at least afford the tokens to go over the work a 2nd, 3rd, 4th and 5th time and gradually fix most of the issues, but it was a very frustrating mode of work.
I'm on the Z.ai quarterly subscription plan (got in when the price was lower) and I was using it through opencode and it was like I'd only get maybe an hour of usage (if that, sometimes) before it would time out and say come back in 5 hours. Now I'm using it through their Zcode harness and I rarely hit that - they say they're giving 1.5x usage if you use it through Zcode, sometimes seems like even more than that.
> Right now unless you're paying by the token, there's no cost based reason to use the open weight models for daily coding work because the monthly coding plans from Anthropic and OpenAI are a better deal.
Maybe. I am on a $20/month Anthropic subscription this month but I also use Claude Code frequently with Deepseek v4 flash and pro, GML5.2. For simple work Deepseek v4 flash is so nice because it is fast.
What you say is true however, the US hyper-scalers are still (desperately?) subsidizing subscriptions for market share to boost there valuations.
I really want to see AI inference costs approach zero, and I think I just need to wait a few years to see that.
I've been avidly using Fable since it was re-released and while it has been excellent at building the apps I want, the reasoning has been completely opaque.
Kim, however, has exposed the whole reasoning trace, or enough of it to matter. I'd almost forgotten how nice it is to see this. I've been able to see all of the weird twist and turns it takes and it is joyful. But also, far, far more informative and means I can debug ideas far more thoroughly. Also, at a first glance it seems to have gotten quite far on a niche hobby horse of mine that no LLM has been able to crack. I'll be testing this more for sure.
I have severe complaints about Anthropic's product managers on this front. Their preference for hiding, obscuring, and trying to wrest control from the user are a bit harrowing. It would be wonderful to go back to Claude Code from before March. It seems like every release destroys value for me!
Anthropic’s position being that it is entitled to train models on the creative works of anyone at any time, but its own slop generators’ outputs are sacred jewels that must be protected from being learned from.
The reasoning is key as most of the time the summary provided by fable is not enough to understand the choice and correct the logic. You have to either fully trust it or go to an exhaustive code review. This with the fact that you can only use 4.8 to security review the code produce by fable are the reasons I will not renew my anthropic subscription, the current experience is way to degraded.
Does it have safety guardrails that constantly false positive like Claude does? The only obvious change I’ve seen since opus 4.6 came out is that it constantly flags my requests (no, I’m not doing biology research or security research, yes, it flags for both of those things).
Recently, they backported the blocks to Opus 4.8, so I’m reluctantly stuck on sonnet.
I probably could successfully apply to get special approval to use claude code unencumbered, but I don’t think it is ethical to support tooling that’s built so a central authority gets to decide what intellectual endeavors and knowledge work are permissible, and what are not.
I feel like the quickstart is missing something. It's referring to its tech blog for actual benchmarks, but K3 isn't mentioned on there, the last thing on that blog was K2.6, 2 releases ago.
also its pretty big model inference costs are high even with margins running a 2.8T model costs a lot. if they release oss may be it goes down to $10-12 per million tokens.
Are thinking models only the reasonable tradeoff vs using much larger non thinking ones because the cost of output tokens is below that of input tokens?
The thing is - as a European, I can choose between plague and cholera.
One has mostly been reliable, stayed peaceful towards us and is primarily concerned with their internal matters and the countries right next to it. They have long-term strategy and understanding of win-win situations.
The other one keeps threatening to invade/steal Greenland. Keeps waging an economic war against the entire bloc. Positions their propagandists right in our middle and does the best to influence our elections. Exports fascism and finances antidemocratic forces. Supports the genocide in that certain country. And still have their soldiers in our country, against the wishes of a majority of the population. Oh and they don't honor any treaties if they feel like it.
Easy choice.
Does that make china an angel? Hell no, they are still committed to enslaving the Uyghur people, keep threatening neighbors and are mostly han supremacists. Human rights are seen as merely a suggestion by them.
But at the time being, one is clearly more reliable than the other. Long-term, I'd like to avoid both the US and China.
And then I'm of course going to root for getting rid of them.
What alternative would you propose? Currently, there's no alternative I know of, either you rely on the US or on China or both.
Me and many others are doing our best building that alternative and promoting local solutions in all areas, but it takes time. And until then, I'd like to use the one that isn't threatening to steal our territory, thank you very much.
You are rooting for the dictatorship that has 0 political freedom, devalues their currency and hurts their own population, they kill their people and cover it up, and have no freedom of speech.
You did not offer me an alternative. Please don't move the goalposts.
And I'm still not rooting _for_ them, I'm rooting for choosing their services above american ones for the time being. That's quite a different thing, as should be obvious. Respond to things I actually said and not things you think I might possibly think.
No, just aesthetic trivia that can be paraded around to make them look good.
Given how China behaves it should be evident that the only reason they don't apply military force is because they are not in position to. Not abusing military strength is not exactly being the paragon of virtue when your opposition could probably glass the world thrice before the day is over.

>Oh and they don't honor any treaties if they feel like it.
I don't know how anyone can really mention any of these when trying to paint a bad picture of anyone as compared to China. It's just an obscene exercise in ignorance. I just can't make sense of discourse like this except as a result of propaganda.
I won't go through everything, but just as an example:
You are not mentioning the greenland situation - why? That's the really big one and the one that made the US much closer to "enemy" than "friend". After all, friends don't threaten to annex your territory.
Regarding propagandists and financing of antidemocratic forces: this refers to a current issue. US is deliberately financing spreading of its ideology in the EU, as they confirmed themselves. [0]
With the genocide, that discussion I'm going to stay clear of, as nobody will be convinced of the other position anyway, too heated. Shouldn't have mentioned it in the first place, as this always leads to flamewars. mb.
Regarding honoring of treaties: let's start with the budapest memorandum - I think that was the first really big one. Then, the 1967 Refugee Protocol which forbids third-country deportations. Then, the UN Framework Convention On Climate Change. Violation of the UN charter, withholding of promised funds. The Convention Against TOrture.
Then all the broken/ignored/overturned trade treaties, all the promises made and not kept - how would anything rely on their word at all anymore?
I could go on for multiple pages. Why do those not count? Why do they have to be "propaganda"?
It is unbelievably difficult being reliant on the US in any way right now. And that's what I'm talking about. Not, which is the "better" country. Reliability and ... well, utility to its partners is the basis of it all. Which right now - compared to china - is rapidly sinking. So where is that ignorance you are speaking of?
> Since 2014, the Chinese government has been accused of subjecting Uyghurs in Xinjiang to widespread persecution, including arbitrary arrest and detention, forced sterilization, and forced labor. This is denied by China.
I'd much rather give my data to China because I don't live there, so there's not a whole lot they can do to me. The US, on the other hand, has a lot leverage over my life and freedom.
and yet here you are on an american site providing data. what about youtube or reddit? I don't think you actually care in reality. otherwise you wouldn't be here to comment.
It's an open model, you can just wait a few days and you'll get to choose who to hand it over to, or given the resources you can run it on your own box.
Right at this moment, there are more people in the world on the side of China than on the side of the USA. Which can translate into raw market numbers at some point. So these comments are kinda moot.
That is correct, but that’s not what I’m talking about. A lot of people complain about handing their data to Chinese government. My argument is, as of today, people like China more than the US. And the American government has publicly said that they’re basically controlling all AI labs if needed. So yeah.
That’s not what this indicates. This is the biggest and most expensive to serve, and most capable open weights model yet. They’re just pricing it in line with capabilities.
Kimi also offers generous subscriptions. Subs aren’t going anywhere. Think of subs like running an insurance business. There might be some users you lose money on (ones who max out their weekly quota without fail), but they’re managed such that the average subscription turns a healthy profit. There’s never been subsidies in model serving, inference is just cheaper in terms of ops TCO than people assume, and API margins are very high.
> They’re just pricing it in line with capabilities.
So... convergence?
> but they’re managed such that the average subscription turns a healthy profit.
It didn't work like that, or at least that's not how it played out. People max-out their subs all the time which is why strict and multiple limits were implemented by all providers. Also, I subscribe to z.ai and recently they dropped the quota significantly that now their sub offers less than Claude and OpenAI. It's still x5-6 what it would cost on API costs though.
> inference is just cheaper in terms of ops TCO than people assume, and API margins are very high.
API margins (at least american ones) are probably healthy. But I don't think that inference is that cheap. It would cost 300-500k to just run GLM 5.2. There are lots of other factors too: reliability (can you keep the GPUs running all time), electricity cost, sys. admin costs, location costs, etc.. I wouldn't be surprised if the API margins are quite close to operational costs.
The link has 6 well-known benchmarks where this beats Fable (out of 14 I counted). If the numbers hold up scrutiny, this is scary good.
Forget about their pricing but the companies that do have means to host such models fully on-prem are also the same companies that are paying tens of millions of $ in inference cost every month, and are by extension the biggest customers of OAI and Anthropic
I don't want to cheer against my country, but we've given up on open source. The way Anthropic and OpenAI treat their customers as adversaries is embarrassing.
I will cheer for China, for Kimi, and for z.ai until we have something in the same category.
[1] I'd even be fine with open weights, fair source, or anything that let us have direct access to the weights. Even if that came with stipulations. Don't hide the weights from us.
I am with you in the spirit of openweights but I am trying to hard-avoid bringing countries into this. The narrative of US vs China only benefits those who want regulatory capture in the US since attacking China is politically much easier than attacking open-weights, so certain groups like to repeatedly call them 'Chinese models'.
It's much more a rallying cry for open weights funding than it is for regulatory capture.
The argument on our side wins - if America or the West don't do open source, China will. And that means -- with certainty -- that China wins the market.
Every politician and VC should hear that loud and clear.
I think given how much benchmaxxing we're seeing - the anecdotal evidence of how competent this model is (and efficient) will depend on user's actual real-world use cases.
Given the pricing, it suggests that this model is much more efficient/competent than previous-gen OS/distilled models.
This is weird and reactionary. Lots of organizations are continuing to refuse to use chinese models due to security and IP concerns. Anthropic/american models aren't going anywhere anytime soon.
I suppose this is like when Anthropic was using “prompt modification, steering vectors, or parameter-efficient fine-tuning” to poison the work of people working in the LLM field, including academic researchers.
When the model is open weights you can even pass every token (including the chain of thought) though a fourth-party lightweight model like gpt-oss-safeguard to check that it has not become adversarial.
I feel like that's a threat that isn't super difficult to block. Unplug it from the internet, require it to go through an API intermediary to access web pages.
It could, but exposing that would doom the company entirely, and AI doesn't generate code with near the quality needed to get a model to mass adoption, insert malicious underhanded code, ensure that consistently looks innocuous enough to never be noticed, and- most importantly- actually exfiltrate data without being noticed. Once it is noticed, it's game over across the board.
> Lots of organizations are continuing to refuse to use chinese models
Correction: Lots of organizations are refusing to use Anthropic Fable because they have forced opt-in data collection as part of their privacy policy, even for Enterprise.
Both things, and both reasons, can be true at the same time.
Not everyone's going to care about Anthropic requiring data collection (a similar debate plays out with regards to "pay or consent" on website tracking), just as not everyone cares about China with regards to security/IP issues (if they did, a lot more would be banned besides occasionally-Huawei).
I would assume the opposite is true — with an open-weight Fable-class model, doesn't demand for GPUs go up? Plenty of companies can now look at what Anthropic is offering — high per token costs for a very intelligent model — and do the math, and at some point it makes sense to just rent the GPU yourself and run Kimi on it if you get similar intelligence without paying Anthropic's margins (albeit with high upfront capital cost).
This would drive down Anthropic's margins, but drive up demand for datacenter and GPU capacity. It's not that people would be using fewer GPUs, they'd just shift demand from high priced token vendors to direct GPU rental, which benefits datacenter companies while hurting Anthropic.
Oracle is fine, it's just that they can't really expect political decisions that hindered it to accquire TikTok which will be slated to be the biggest customer if the deal went through.
Now they are betting with Project Stargate but it also seems to be crumbling down.
But don't forget that they literally hold the biggest databases, both in commercial and open source, that is, Oracle Database and MySQL. Plus Oracle Java they literally controls at least 30% of the internet's software infrastructure.
And also with a good team of attorneies enforcing the licenses, they can squeeze so much money at the cost of morality.
Also recently they downgraded the always free OCI ARM instance from 4C24G to 2C12G without telling anyone.
New enterprise java licenses are going to milk enterprise just like broadcom is doing. New license deals makes you pay for employee total number (including contractors) instead of for users of oracle java.
They're drowning in debt and risk is increasing. If these US models don't keep holding up their valuation will tank further and some will recall the loans or ask for different terms.
These "real world" examples are nothing like the way I use LLMs from within a harness. GPT 5.6 Sol and Fable are clearly more impressive, but how does this translate to interactive agent use, or use under an agent orchestration framework?
As much as I like GLM 5.2 it's clearly a step below Opus (or even Fable) for more complicated tasks. I would place it at Opus 4.6/4.7 level.
Having said that, the safety system on Fable makes it an extremely unattractive model. It feels that half of the time you're paying double for Opus level performance.
GLM has issues with tool calls and nested JSON and it wastes tokens pretty often. I see it being a bit above half the price of Opus in a bit more complex eval tasks. With some RL you could probably get the tool calls sorted and the price down.
(As an aside, I don't know how it was professional of Arena to unmask an unreleased cloaked model on their platform. Also practically, upstream could have been A/B testing multiple variants under same endpoint, casting validity of such pre-announcement tests into question)
Crazy how their models always come out after the US labs and just lag the performance of top models. Almost like they are performing distillation attacks... how strange.
Distillation is not an attack. It simply a way to train a model. Not doing it when you are behind is akin to snatching defeat from the jaws of victory.
It is an attack at a sufficient level of sophisticated analysis. If you destroy the game theoretic first mover advantage, then you destroy the economic incentive to improve things.
Given that model distillation has existed since the early days of the current AI boom, and no robust defense has been demonstrated, the available evidence does not support your theory.
> As an early proof of concept, Kimi K3 designed a chip to serve a nano model built on its own architecture. In a single 48-hour autonomous run, K3 built, optimized, and verified the chip using open-source EDA tools on the Nangate 45nm library. Within 4 mm², the chip closes timing at 100 MHz and sustains over 8,700 tokens/s decode throughput in simulation, packing 1.46M standard cells, 0.277 MB of SRAM, and an INT4 MAC array with fused dequantization. A chip built by a model, for a model, reflects K3's long-horizon agentic capabilities.
groq did an ASIC for llama and now for nvidia. Their cloud service is fast.
> NVIDIA Groq 3 LPU Inference Accelerator
> The NVIDIA Groq 3 LPU is the next generation of Groq’s innovative language processing unit. Each LPX rack features 256 interconnected LPU accelerators that, together with the NVIDIA Vera Rubin platform, supercharge inference. Each LPU accelerator delivers 500 megabytes (MB) of SRAM, 150 terabytes per second (TB/s) of SRAM bandwidth, and 2.5 TB/s scale-up bandwidth.
I had a thought a while back: sell large local models burned onto fused compute / ROM chips. Like cartridges for old game consoles. Slot (or probably plug into USB-C) and go.
It’s an ASIC with the model wired into it so it’s very low power and fast.
I’d buy these. Say $100 for a frontier class model. Maybe more.
Taalas is developing this, but not for Frontier class models. I hope that if we can least get the easy 80% of work done on that sort of hardware, we can greatly reduce the demand for GPUs, HBM and energy to some extent.
There is an amount of brute forcing that becomes possible at those speeds that I think could even take us beyond 80%. If we could have Qwen3.6-27B running at 15k t/s, run 100 attempts concurrently, select top-K solutions and synthesize a final result from them.
There was a paper a while back that showed top-K selection like that with tiny models was able to reliably solve some 1M-step Tower of Hanoi when no frontier model could. Very big level up in capability just from horizontally scaling compute.
But some (Meta, Anthropic) suggested that optimizing and extending the "<think>" process can produce extra value. (I do not know if that requires an improved underlying architecture - frontier models architectures are sometimes not public.)
I believes the weights are burned as ROM microcode, but for an effective inference speedup, you do want to burn the architecture (matmuls, activation functions, MoE gates, etc) as well which will differ from model to model.
It's not as simple as a weight swap between identical architectures.
The speed gains are also from not having to route the weights through wiring like with ROM cartridges.
Interestingly, you could easily run them from the said old consoles! You'd just need a bit of console code to interface (text input/output) with your fully independent LLM subsystem. Imagine Claude for the NES without Internet?
This would be very compelling. Can anyone share more details on how it would work? Only issue is that you are stuck at a certain point in time but that’s not a huge deal. Even just a good 27b model would be useful.
Talaas have done this with a llama 3 model.
Runs at like, 16k/tokens a second oror something obscene. Very little power draw too.
Doesn’t need hbm or lots of memory, because the hardware can just forward the data straight to the next layer and you don’t need to round trip through memory.
They claim to be working on an approach to make the underlying hardware a bit more reusable between models.
Yeah, if you have a fixed llm topology, you can just effectively burns 2 top layers of the chip as Rom (model weights) - which has a per area density even better than dram - so it’s just attention and kv streaming that is hbm to sram transfer.
Most big model weights will not fit a single reticle sized chip - so you’d have prob 30 different chips to split the model .
And you’d need super fast chip to chip comms for the all-reduce and similar.
So scaling to 1T models is hard - and a long lead time - but can be very power efficient.
1) the hardest, custom silicon + MCU to manage the USB interface
2) not as hard, shared memory, NPU + MCU to manage inference and USB interface
Theoretically you could do 2 with the right MCU, NPU, and memory combo. You'd stream/DMA the weights from memory into the NPU and then read the results with the MCU. From a user's perspective, it might take the form of an openAI API compatible endpoint that enumerates when they plug the USB device in. There would likely be some host-side software to ease the pain of trying to use a USB device as an HTTP API.
You’re expecting the wrong thing. The demo demonstrates the insane inference rate of dedicated hardware. Iirc it’s llama 3 or something. Not a very good model by today’s standards. But it runs at 16k tokens per second, an order of magnitude above the competition.
Imagine what’s possible if you had GLM-5.2 turned into a hardware chip like this.
> I’d buy these. Say $100 for a frontier class model. Maybe more.
Sure you would. Running frontier class models on current hardware costs in the order of tens of thousands of dollars. It is more likely that these custom ASICs will be priced competitively with that, and not with Super Mario Bros.
Oh, and energy consumption will be in the same order.
I wonder, if you can run at 8k or 15k t/s, you could in theory run 10 or 20 agents (or more) at the same time and generate hundreds of versions, then just analyze them. Think thinking mode x1000 at least... Would be interesting to see how good it would be
The K3 marketing popup when I look at the Kimi Code page says "Kimi K3 Open Frontier Model". So, if it's not going to be open, they haven't told the whole team, yet.
That's a quickstart page for using the model on the platform not a page about the model. I am skeptical you are correct that it said something about model license earlier.
Not the person you're responding to, just a person who still has the original version of the page open in their browser. Quoting from it:
"Kimi K3 is the first open-source model to reach the 2.8-trillion-parameter scale. It is the latest step in Kimi's continued push of model-scale boundaries: in 9 of the past 12 months, Kimi models have set new records for open-source model scale."
The page has definitely changed.
(I'm not sure why you would be skeptical of somebody recollecting something they probably read only half an hour earlier.)
According to artificialanalysis, cost per task is $0.94, which is almost the same as $1.04 of gpt 5.6 sol max (fable is most expensive by far, at $2.75). Things like glm 5.2 max cost roughly half that. The model certainly sounds extremely impressive for something not from openai/antrophic, but the price makes it a mediocre product.
Instruction following seems lower than I’d like, too. OTOH scores on agentic stuff seem high, which… feels a bit contradictory? I thought decent instruction following is step 1 of solid agentic workflow.
The benchmarks look nothing short of incredible. Assuming it’s not benchmaxxed to hell and back it’s just a notch below gpt 5.6, which came out what, a week ago? If the performance claims hold up the delayed Gemini 3.5 pro will likely end up not only behind fable, but also behind 5.6 and a (supposed) open weights model. Google might have to do some real soul-searching.
I've put links to the posts on GLM5.2, Opus 4.8, Chat GPT 5.5. I grab video screencaps so you can compare in detail. The full interactive Kimi output is at the bottom of the post if you want a comprehensive 3D play around
Judging from the behavior It’s possible that the chat/ux model does know and has an unbiased opinion about china, but the filtering is on the front end/client side and so the user facing model has not been fine tuned natively. The reason is probably because it’s not easily to change only one part of the model without affecting safety in other parts. We know this e.g https://youtu.be/b-nD3HgIR5Y?is=TeyXnaNMNndqWqax
It’s quite likely that API
Models also
Have this filtering, but I
Haven’t tried. Anyone had luck to get it to spill its beans on the api side(almost)?
> It’s possible that the chat/ux model does know and has an unbiased opinion about china, but the filtering is on the front end/client side and so the user facing model has not been fine tuned natively
This has always been the case with Chinese models. Their web ui is a service provided from China, so they are required to censor it, but not the models themselves.
There is no such thing as an unbiased opinion, opinions always contain some sort of value judgement. Besides, training data contains biases.
What is plausible is that they haven't made any attempts to explicitly steer certain opinions into a certain direction, and just let the model take over the bias of the training data, whatever that may be. Filtering in the front end is the easy, lazy way out to be legally compliant.
2.8T param open model, 1M context, native vision. Weights releasing by July 27 with technical report. Launching with max thinking effort by default; low/high effort modes coming in future updates.
These benchmark numbers are insane. The days when China was 6 months behind are over? How are they doing this with so much less resources than the US??? I have so much respect for the researchers there
I'm not sure where "so much less resources" comes from. Training the best model has nothing to do with having the most NVIDIA GPUs around. If that were true then xAI would have the best model. It comes down to the quality of data, research, and financial backing.
Mythos/Fable-class models have been around for at least 4 months internally in the US, and Kimi still isn't quite there, so I'd say the 6-months is still about right.
Initial testing for Mythos was in April 2026, right? Sure, they had the model internally before that when they were working on it, but the same is true for Moonshot and K3.
On the first try, Kimi K3 just found the source of a bug that Fable 5 hasn't been able to pinpoint in multiple attempts. It's just one anecdote, and I haven't used K3 much yet, but so far it's looking extremely promising.
Update: the subscription limits are pretty brutal. My first impression is that the $100 subscription eats into the quota at a pace similar to the $200 Anthropic subscriptions when using Fable.
But the model itself is amazing. I think I might put this above Opus 4.8.
How do you use kimi for agentic tasks? I'm used to claude code & codex extensions for vs code, but recently switched to codex cli w/ vim keybinds. Does something like that exist for openrouter?
I've been happilly using kimi models via the $10/month opencode-go[1] subscription for a few months now. I also use pi[2], instead of opencode. Their extensions api is nice, though OpenCode's is similar. My personal preference is more minimalism, add extensions when I want them, instead of the kitchen sink approach.
This is entirely for personal use and small projects. I don't have huge needs. I get access to gpt models via my employer for work things. But I'm also using pi with those models.
I don't use Codex CLI myself, but you can configure it to point to OpenRouter instead. OpenRouter has some instructions for Codex CLI and Claude Code here (though they mention Claude Code is not guaranteed to work!):
Working with chinese models is giving me a fullfilment sensation. I think that I have enough quality for the work that I need to do and lots of extra tokens to work with. With Claude and ChatGPT I reach the limits fairly easy, but not with OpenCode Go. So I will use Claude once in a while for difficult tasks to see how much better it still is (but use Chinese on a daily basis)
OpenCode Go is a great deal but I recently dumped my subscription because I found myself rarely reaching for it over my Anthropic sub (I can get 40 hours of work a week out of the $20 sub and almost never hit weekly limits). Subscribed to OpenAI as my secondary and I've been really impressed with that too so far.
I expect if they add Kimi 3 to Go the limits are going to be really low since 2.7 is already one of the most limited models and 3 is much larger.
I have been using Deepseek V4 Pro for personal projects and it has been great. I think the $20/mo GPT plan is still the strongest value, but only because you don’t have to pay API prices for tokens.
Just in case you were thinking of signing up directly with Moonshot to use the service, they appear to train even on API use:
> We may use Content to provide, maintain, develop, support, and improve the Services, comply with applicable law, enforce our terms and policies, and keep the Services safe and secure. Customer who requires restrictions on the use of Customer Content for training or improving Moonshot AI models may contact Moonshot AI to discuss available enterprise arrangements or separate written agreements. Unless otherwise expressly agreed in writing, Customer Content may be used for the foregoing purposes.
I pretty sure OpenAI and Anthropic are doing the same or worse. Keep in mind that these companies are in the business of stealing IP work and reselling it to you with "safety checks" so asking if they use your usage data for training is a bit naive at best. At least the Chinese companies are more open and give back to the community compared with the "frontier" providers.
>> No they're not. It would end both companies if they were ever found to be doing that.
Their terms are clear -
The argument here is that with the Chinese labs you have zero legal recourse.
Their terms are not worth shit considering they are reselling you stolen copyrighted data. Even in they terms they started clearly say they retain your data for "safety reasons" for however long they want. Perhaps you didn't watch the space with Anthropic going back and forth with ToS updates(we retain your data for 30 days...stike that and add 30 days or more or no or ..whatever) like my own alpha website.
Your argument boils down to "they've done something I find objectionable, so that means everything they say must be lies".
I'm not comfortable with how these models were trained. I have quite a bit of open source code out there, and I personally see such training as copyright and license laundering.
But that's not how the law sees it, and I grudgingly accept that, regardless of how I may feel, and I don't let my feelings on the matter make me think irrationally when it comes to whether or not these AI companies honor the terms they provide.
Sure, they might be breaking their promises, training on our data when they say they won't. But I do think they most likely aren't, and that it would be corporate suicide if they were and it ever came out.
Anthropic paid several billion dollars to settle a lawsuit they were likely to lose. OpenAI is now about to get taken to the cleaners for corporate espionage against Apple. They do not give a fuck about the law. Paying $5 billion for some fines is a trivial cost of doing business when you're aiming for trillion-dollar IPOs.
> make me think irrationally when it comes to whether or not these AI companies honor the terms they provide.
Irrationality is thinking there's such a thing as honor and that companies which have repeatedly broken the law for data won't do it again when there's no enforcement mechanism that acts as a real deterrent.
Their argument boils down to "they've done it once and nobody prevents them from doing it again"
This dog-and-pony-show is a rehash of the Pascal's wager we saw with smartphone security. Everyone thought it would be "corporate suicide" to hack an iPhone, but NSO Group did it. Apple sued NSO Group, and then settled out of court immediately after. Now we live in a post-hacking world and everyone pretends like this is an unavoidable necessary evil that corporations are powerless to stop. Suggesting litigation is a comically useless strategy because the law rubberstamps any form of useful surveillance or retention. Failing that, NSO Group has enough sycophant lobbyists to smear anyone that takes their threat seriously. Look at OpenAI and Anthropic and tell me that it's not the same hostage situation; can you?
You can do whatever stupid stuff you want to with your data. But this is an absurd amount of faith to give to guilty businesses, on the level of planning your world domination schemes over Skype.
* Exploiting ambiguity around fair use at a large scale before the law catches up and then jointly lobbying with your competition to make sure your interpretation of the law becomes reality.
* Explicitly signing a contract with enterprises to respect their IP and then proceeding to break that contract with your own customers.
The former is firmly in the gray area of legality and doesn't directly hurt your own customers. The latter is both an unambiguous contract violation and a flagrant attack on your own customers' most valuable asset.
First: This is the general privacy policy, not the enterprise contract. I don't know what goes into the enterprise contract, but I do know that our legal department spent a very long time making sure it was satisfactory before we got access.
Second: My argument doesn't hinge on Anthropic not being able to weasel their way out in court if it came to that. My argument is that neither Anthropic nor OpenAI are going to break their signed contracts or even fudge on the clearly communicated understandings of what the terms of the API pricing are because neither one wants to hand the other the obvious weapon of: "unlike {other guys} we honor our word".
It's just not happening, and comparisons upthread to the fair use story totally misunderstand the incentives at play here.
(And as an aside, this whole thread also shows clearly the classic programmer misunderstanding of the law. The peanut butter sandwich instructions analogy is for code, not for the law. The law doesn't actually work by allowing any possible interpretation to hold equal weight the way that many programmers think it does.)
> The law doesn't actually work by allowing any possible interpretation to hold equal weight the way that many programmers think it does
Is that so? Recent rulings in the US specifically gave me the impression that when backed by sufficient legal representation and goodwill on the judging side indeed any possible interpretation will suffice.
I think that's what makes law making complicated - you either err on the side of leaving too much room for interpretation or not enough.
retention for 'safety' -> AI race as national security -> training on your data for 'national security' aka safety
It's simple mental calisthenics. If you are handing an organization whose entire business model is built on stealing data with spurious reasoning, what do you actually expect they will do? Don't be a fool.
This argument would hold more weight if Anthropic and OpenAI main customers weren’t massive trillion dollar companies with legal teams capable of burying just about anyone, anywhere, for even the mildest contract violation. Something that OpenAI is getting some close up experience with at the moment.
That suggests the system working as it should. They present terms for use, you don't like them, so your don't use it. One of their other products has terms you're ok with, so you use that product.
Good, fine. This is an example of trusting the company to honor their own terms, not the opposite.
Anthropic paid a large settlement for the copyrighted data they pirated. So far, US courts have found that it's perfectly fine to train AIs on copyrighted data for which you have legal access.
> Even in they terms they started clearly say they retain your data for "safety reasons" for however long they want.
The discussion was about training, not data retention. Two very different concerns.
And if you're a decent sized customer, most providers have a route to not even retaining the data for safety/security reasons. The reason Anthropic had issues is because they do have a path to "no data storage" for Sonnet/Opus, but not for Fable. Which is why at work we have access to the former, but not the latter.
Whether the terms are worth shit doesn't matter. If they're training on data from paying customers who have requested otherwise and it gets out (which it would, eventually), SAP, Accenture, Deloitte and other huge companies with well-funded legal teams would nuke them from orbit. This is a different area of law from the copyright stuff, different rules/norms/expectations/consequences apply.
So because it would wreck they if others found out, it’s unlikely?
Which is more likely? That past behavior is an indication of future behavior, or that they because they could be eliminated from being found out it’s unlikely they’d do that thing. (By the way it’s also likely they’d are eliminated if they dont train their data with every advantage over their competitors possible). So I think it’s naive to think the incentives reward not doing the malicious thing now.
If you are a regular user they could care less,if you are enterprise they might be more careful. They have credit card info, and all your chats so I’m sure they can figure things out
I think we all ought to look at the ZDR fine-print here.
I get that in principle that there's no retention, but these are powerful models that can comprehend, paraphrase and summarize your logs for the sake of "product" improvement. Who knows what's collected here.
> [Mr. Tan] has directed job candidates still working for Apple to bring “Actual parts” from Apple to their interviews for “show and tell” sessions in which he and his team at OpenAI can elicit still more Apple confidential information.
> As part of its investigation, Apple found a “pattern by employees who depart for OpenAI of taking steps to evade the security processes intended to protect Apple’s confidential information.”
> Apple also claims former engineer Liu exploited a security bug to download confidential engineering files after leaving the company. Rather than report the exploit, Liu allegedly joked about it in messages (“LOL,” “so funny”). Liu also failed to return an Apple-issued laptop after his departure.
This seems pretty close to "they trust me, dumb fucks" behaviour.
They could use an agent to summarise the source material, and then train models on those summaries, and claim that some sort of clean-room training has happened?
Anthropic constantly uses dark patterns to steal training data from customers (like the “how is claude doing” spam, data retention loosening when the safeguards false positive, etc).
There are multiple ways to use feedback. Personally I would often be fine with actual human reading my feedback, taking in account the points I made and evaluating how it should affect their feature development and future roadmap.
Now what I would expect AI companies to do is to take things which were submitted as feedback and pretty much adding to training:
"Do more of this: <copy of the whole response which was flagged as good in feedback>"
"Do less of this: <copy of the whole response which was flagged as bad in feedback>"
It's paraphrased, but the point is that they will most likely use it more-or-less as-is and thus whatever is in there will be part of the model's training set rather than someone picking up the parts from response that are important and only including them (which happens with traditional feedback).
If you have a naive loop like this you will quickly poison your dataset with e.g. thumbs downs because someone is unhappy with the latest frontend update, or teach models to not correctly refuse. I’m sure the pipeline is more sophisticated and in the middle.
Sure, but the point is more that once you submit feedback then the usual "opt out of using my data for training" no longer apply and at least that reply (and possibly whole conversation) can be included in training set in one way or another.
They don't use your general chats it if you have opted out (note: opted out, not opted in). However if you submit feedback then whole conversation can be used.
> Even if you have opted out of training, you can still choose to provide feedback to us about your interactions with our products (for instance, by selecting thumbs up or thumbs down on a model response). If you choose to provide feedback, the entire conversation associated with that feedback may be used to train our models.
> If you explicitly report materials to us (e.g.via our thumbs up/down feedback mechanisms), or by otherwise explicitly opting in to training, then we may use those materials to train our models.
No for what? The opt-in for model training? About a year ago Anthropic changed "Allow use of your chats and coding sessions to train and improve Anthropic AI models" to default to on: https://www.anthropic.com/news/updates-to-our-consumer-terms
Or do you mean the feedback stuff? Their KB article at least seems to contradict that.
I think the risk of not doing is more existential than doing so and getting caught. Wouldn’t you agree?
Edit: And the point of the poster is they have already demonstrated a track record of lying and misconduct, so how can you trust their word now? What have they done to show you they have taken responsibility for past actions and changed?
they train on your requests by paraphrasing them (which means rewriting them but keeping all the saliency) and removing their association with you
i don't know why this is so controversial, their terms are written to perfectly fit this training regime. one of you downvoters i'm sure has an enterprise contract with them, just ask.
if you are using bedrock, until very recently, they didn't see your requests and could not paraphrase. but too many people were using bedrock for too much stuff they wanted to see. so that's why the terms for bedrock changed for fable 5. this was the core of the palantir / defense dept drama with anthropic.
* A company following suit with their entire industry in choosing a very generous definition of fair use.
* A company being the first to defect and actually break their signed contracts with enormous enterprises committing to not train on those enterprises' most valuable assets.
Training on copyrighted works signs them up to be a part of a system that is at this point too big to fail and places them in good company with all of their competition. Breaking their signed agreements would open them up to very well-founded and well-funded lawsuits for contract violation and give their competition a huge boost.
All of a sudden "we actually don't break our contracts" would be a selling point. No company in their right mind is going to let what should be table stakes become a differentiator for their competition.
Not the guy you responded to, but I would assume ”they keep it safe” somewhere in a cold storage. Just in case they decide to train on it in a later phase.
There is no evidence for these types of claims. They likely need to retain data for legal purposes (I think all of them are under injunctions from court cases), but there’s no way they will be breaching contracts with all these enterprises just for a little bit of data. Those contracts are their lifeline.
I don't think they'd really be willing to risk the whole company on a small subset of prompts. It's not "keeping it safe", it's retaining proof of illegal activities.
You truly see no difference between having a perhaps-overly-generous definition of fair use and flagrantly breaking contracts that you signed with your customers?
Because the legal system does, in fact, have teeth. And those teeth actually deploy pretty readily. Especially when the people whose trade secrets you would be violating are gargantuan companies with enough resources that the cost of a lawsuit is a rounding error.
Obviously don't know for sure, but I can very easily seeing a combination of "move fast and break things", "it's easier to ask for forgiveness", "too big to fail", "I know tech, so I know everything", "AI is gonna change the world so fucking much, it doesn't matter what happens now", and finally "I cannot fail! I must make it work!" making especially con artist Sam just straight not care.
Does it? Because these companies systematically broke copyright law by illegally downloading terabytes of copyrighted content and there's been no consequences.
Past behaviour informs future trust and I wouldn't trust these companies whatsoever.
No AI company has been reselling copyright data to my knowledge, it would be truly bizarre if they did that.
What they have been doing, with some narrow exceptions where they have lost billions of dollars in court cases*, is not at all obviously prohibited by copyright law. Neither web scraping (i.e. asking for copies of data from people you have every reason to believe are authorized to give you copies) or running algorithms on copyrighted data are generally copyright infringment. I say generally because the "algorithm" of "ctrl-c ctrl-v" is obviously an exception, and there's some argument that training is similar enough to be illegal - a fairly weak argument that is mostly losing in court but has some tiny chance of still succeeding.
The law doesn't have teeth to prohibit things not prohibited under the law - no matter how much many people would like them to be prohibited. This shouldn't be surprising.
Unlike with copyright, the law does pretty clearly prohibit violating contractual terms to not hang onto or use other peoples data for purposes other than the narrow ones laid out in the contract when you agreed to the contract.
* Namely acquiring copies of data from people who they know aren't authorized to make copies - i.e. torrenting.
To an extent, though for significant (in monetary terms) violations of the law the teeth tend to pay for themselves (but do so by not fully compensating the people whose behalf they are supposedly acting on).
More problematically there are camouflaged sharp spines pointed primarily in the direction of poorer people, and people not advised by lawyers.
But none of that matters here when the damaged parties include the megacorps of the world.
I would assume at this point that any SaaS product, LLM or not, where the data doesn't reside on your servers on your premises (or your own colo) is training on the entire corpus of your data, whether they'll admit to it or not.
OpenRouter's ToS also seems to allow them to store your submitted prompts anyway, so privacy advocates would have to look elsewhere anyway, that's at least how I understand it (and it surprised me).
If they want to take my awful prompts and poison their model with it, it's their loss.
For anyone else that believes their input needs secrecy, you need to check the corporate plan of any provider for data protection clauses. Most use the cheaper plans as bait to get more training data and free feedback.
You think openai, anthropic, google, z and any of the others dont?
They do, if they say they dont, they do. Who wouldn't in this earth-shattering race. So Naive
I'm a bit nervous this one isn't going to be open-weights. Any mention of "open" has been struck from the literature for this model (it was present an hour ago). We don't even know active params?

11 days is a long time. It does not take that long to implement inference at providers. In my opinion, seems like they're being pre-emptively cautious about government intervention/review
Actually it does for a massive model, serving it correctly is not easy.
I believe Kimi also does some sort of Q&A and eval for day 0 partners, since early on a long of inference providers just weren’t running their models properly.
Reuters has been reporting that Chinese government is undergoing similar investigation to the US; blocking the export of domestic frontier models. They boil down to "anonymous sources" but it does seem inevitable as the tech gets stronger and stronger.
It came (at least in part) from a document in May where the CCP pretty much said that they will need to review models to make sure they don't threaten national security.
Which basically translates too "Don't give away tools that can be used to undermine your own goals".
literally no one owes you anything, has nothing to do with age. You want open weight models? Go build one, but don't expect companies to do it for you because you're special.
Thanks for the link. No need to be so aggressive. The blog with that detail was not live before; and they removed that language from the original link in this post.

Really good benchmark score it seems. Maybe another DeepSeek moment right here.
That’s not what second means in this context in English, and it’s incorrect to use it that way. This is because for something to be second there must have been something in first and only first, and so on; in this case there was a first and a second already, and you cannot amalgamate then because they didn’t tie (and even if they did, they’d be 1 and 2). Both logically and grammatically, it’s incorrect.
France’s football team is second only to England’s and Argentina’s.
It’s a miracle that in language same words have different meanings depending on context. If this wouldn’t be the case we could have hardcoded NLP algorithmically without inventing these expensive LLMs!
Which is still great because it means neither of the two best financed labs in the world manage to produce even two models themselves that would beat Kimi K3.
In my experience, the Chinese models are much more benchmaxxed than their frontier lab competitors, so I'm taking these results with a fairly large helping of salt.
> > K3 pushes the boundary of end-to-end knowledge work. On the GDPval-AA v2 leaderboard, Kimi K3 scores 1687. The benchmark evaluates AI models on real-world tasks across 44 occupations and 9 major industries; Kimi K3 ranks behind only Claude Fable 5 Max and GPT-5.6 Sol Max, and ahead of Claude Opus 4.8 Max at 1600.
This is the same benchmark where Sonnet 5 outperforms Opus 4.8 max.
Like all model releases, the benchmarks aren't going to tell the whole story. All of the open weight models come with amazing benchmark results now. It's hard to believe anything other than that the benchmarks are leaking into (or intentionally included) into training data.
Possible, but pay-as-you-go Hy3 / DeepSeek v4 Pro / MiMo v2.5 Pro (from respective vendors) are genuinely good enough as daily drivers, given the costs (especially, low prices for input cache, which usually makes up 70%+ of total input for agentic workflows). I put in $10 in DeepSeek & Xiaomi MiMo, and I've barely used $1 each, in a week of coding work.
Coding Plans by MiniMax ($20/mo for 1.7b tokens) and Z.ai (~$30/week use for $17/mo) are also tremendous value for money.
It was also disruptive because it was open weight, meaning anyone and their dog could theoretically compete with the frontier labs for their inference revenue.
The frontier labs need to recoup a huge amount of cash to cover their model development costs, and justify their valuations. That’s plausible when they’re only ones capable of selling inference on these models, it a lot less plausible when models themselves become cheap commodities, and you’re just competing on your ability to provide compute. Anthropic and OpenAI can’t compete with people like AWS on that front.
cost has nothing to do with why deepseek was disruptive, the fact that it means there is zero moat around anthropic or openai is what's disruptive about it. it means in the mid-term LLMs will be commoditized and customers will flock to the cheapest inference wherever they can find it. there's no reason to stick to the "frontier" labs
DeepSeek didn’t really change any trends though, unless you count the stock market.
It was impressive work, but models were commoditizing and inference costs were dropping rapidly already. They were neither the first nor the last 10x optimization, from what I’ve seen.
If you know of any other 10x optimisations currently, please let me know! I'm in the market for a model that's a tenth the price of a frontier model at the same level of quality.
OK, let me be more precise: If you know of a frontier model that's ten times cheaper than the previous frontier model at that level of intelligence, please let me know, I'm in the market for one.
It's different, but similar. If they release the weights, then we have a Fable / frontier model people can tinker with. Either way, it's still quite impressive and knocked a US company out of the top three (google). How long before China dominates the top-10 (if they don't already) or the #1 model?
I finished benchmarking[0] it, but it was not fun, it only supports (max) reasoning and the model is quite slow. Apart from a few requests timing out, it also has some issues with tool calling/response format schemas (Moonshot rejected tools.function.parameters with anyOf schema).
It also, for some reason failed to generate either of the 2 coding demos (hamster svg and solar system css animation).
Intelligence-wise, it's between GPT-5.6 Terra and GPT-5.6 Sol. It's ~30% better than Kimi K2.6, but a lot slower and more expensive.
Yup some here are in denial but what many said would happen did just happen. They're not "six months behind": the model is totally SOTA. Cheaper, faster and they don't just crush Sonnet 5 and Opus 4.8: on 6 of the 14 benchmarks they posted Kimi K3 is in front of Fable.
Of course the shills are shifting their tone: this thread as devolved into "sure yup it's totally SOTA but it sucks because it'll use more tokens than Fable to do the same task".
I take it that's the new tune we'll hear for a while. Oh well, at least we won't have to suffer the "they're six months behind, so they're totally useless" anymore.
P.S: I'll make a prediction... We'll hear the "buuuuuuuuut it uses more tokens for the same task" for a few weeks, then we'll get Fable 5.1 and those same posters are going to post "Fable 5.1 is so much ahead you're missing out if you're still on that piece of turd that Fable 5 or K3 is".
For day-to-day programming work, have you seen a difference in the quality of output between (Opus 4.6 / GPT 5.2 / GPT-5.3 Codex) and the current (GPT-5.6 / Fable) that justifies the price increase?
My intuition says that the output quality difference is marginal compared to the change in price especially when taking into account the effects of prompt/context engineering and harness differences.
Essentially: since opus 4.6, working through a model's quirks with prompt/context engineering and harness development will yield significantly better output than just switching models to the latest.
I don't understand how DeepSeek can be so cheap with their cache pricing - ~0.003 usd / 1Mtok. 100x less than Kimi K3, or similar numbers against pretty much any other decently sized model to my knowledge. I've been using it whenever possible as even longer agent sessions cost few cents.
If you read DeepSeek's papers, you'll find a litany of architectural features that allow for a greatly reduced cache hit price by shrinking the size of the KV-cache.
Many of these techniques haven't been published very long ago - it often takes a good 6-8 months for techniques to percolate. But also, they come at a complexity cost and, seemingly, also at a stability cost.
Also potentially a performance (in terms of output quality) cost. DeepSeek is cheap on a per token basis but lags behind in the benchmarks, perhaps it was a calculated tradeoff.
* Tons of gray testing going on for the last 2+ weeks (people at random getting the new v4 model for a while before its removed again).
* It also DeepSeek their 3th birthday this Friday.
* The its been almost 3 months from the v4 DeepSeek release, and the model everybody have been using, was not post-trained. That is what they have been doing during this time.
People trying out the new DSv4 via the web chat with quick game creation tests. People pulling out stuff like Stellaris clones etc.
The Battlefront like game is impressive. Sure, the soldiers are backwards and the graphics are still kind of basic. But the entire movement system (run/walk/crouch/jump), gun mechanics, grenades, capture points, AI fighting / capturing back, etc ... Ended up playing it way too darn long lol The text is in mandarin but its not too hard to figure out the menu. Sniper is OP ;)
The Horizon 6 game has everywhere mesh colliders, shows when you off track dirt being kicked up, etc ... In general, both example are very well polished minus the reverse soldiers issue.
And the price is supposed to stay the same (beyond the doubling during Chinese workhours), because everybody got that update.
> We also further increased the sparsity of the Mixture of Experts (MoE): with the Stable LatentMoE framework, the model efficiently activates 16 out of 896 experts. Together with improvements in training methodology and data recipes, these structural advances give K3 roughly 2.5x the overall scaling efficiency of K2, converting compute into capability more effectively.
Assuming experts are uniformly distributed (I’m really not that familiar with the deep details there), that’s 2800/896*16 = 50 billion active parameters just for the active/expert part. Wild stuff, and I’m glad there’s at least some companies still publishing (and pushing, for open-weight models) total parameter count.
And: It sounds very believable that this would result in efficiency gains wrt. to compute necessary for “good”-quality inference. Does anyone know whether there currently even are any SOTA or near-SOTA models that are dense still?
No, you can't divide the entire size by the expert count. A lot of weights are constant for all tokens, so total active count is ((2800-(shared)/896)*16 + (shared))
Just to add to that, a Transformer block consists of an attention part followed by a feed forward part. MoE only modifies the feed forward part (which basically contains declarative knowledge getting injected into the residual stream).
2.5x the scaling efficiency, so 4 times the price? What is happening here? Did the subsidies dry up with the discrepancy between chinese and US models?
Scaling efficiency simply means if you took the first small model and scaled it up to the big model it would take 2.5x the resources to run. Not the that larger model is going to be any cheaper.
Kind of like scaling your personal automobile to the weight of a semi, the semi is still going to be far more efficient in moving cargo, not that the semi will cost the same to operate as the original car.
- The blog post is explicitly saying that the model is open; that language was removed from the previously shared link
- It shows benchmarks
I've been playing around with it for the past few hours, and I think it's an amazing model. I'm not sure I could tell the difference between this and Fable in a blind test. The quota in the $100 Kimi Coding plan seems to roughly align with what I get from the $200 Anthropic plan when I primarily use Fable.
I's not just matching against titles. Ironically, I have an agent running daily scans, reading the contents of the top 200 stories of the day. It auto screens high-confidence ones and I make judgement calls on like 10-20 of them per day.
LMArena's "code" leaderboard is really skewed since it's a front-end JS code and design leaderboard. It generates a demo app with two models and then asks "do you prefer A or B". People can look at the code, but most of the time it's just going to be which one looks nicer.
Models that people like the design aesthetic of (Claude, GLM) tend to do better in LMArena than they do on other benchmarks. Design matters, but you look at a model like GPT-5.5 and it's behind Kimi K2.6, Sonnet 4.6, Qwen3.7 Max, and GLM-5.1 on LMArena's code leaderboard. Then you look at benchmarks like DeepSWE and GPT-5.5 blows them out of the water with only Fable and GPT-5.6 beating it.
I'm not saying that the LMArena leaderboard isn't useful, but I'm not sure how much weight I'd give it as a "code" leaderboard. I think often times it's a design comparison of simple front-end React apps rather than a coding comparison. GLM-5.2 is a very good model, but when you look at DeepSWE or Terminal-Bench v2, GPT-5.5 is well ahead.
I didn’t realize that GPT-5.6 is basically dominating the cost/intelligence Pareto frontier right now, at least for this set of benchmarks. Otherwise it’s only Fable on the very high end and DeepSeek on the very low end. This Kimi model gets close, though.
Did anyone see on the blog post[0] that it was able to code up an entire GPU compiler from scratch? It looks like it even outperformed triton on some GPU kernels. That just seems insane to me.
Wonder if they’ll open-source this and show how many tokens it cost.
A really good startup idea right now... Use kimi k3 to reproduce the kimi k3 asic design and start fabbing it immediately. In 12-18 months, start spinning up your own cloud and start competing with the frontier labs ASAP.
Who needs superintelligence with you have 8,700 tokens/s at near Fable levels of performance???
This is like the Bill Gates, Paul Allen moment, but for hardware.
Anthropic's "durable advantage" theory of US AI dominance is looking pretty silly. There's zero indication that it will be hard for China to keep pace as models improve and start contributing to their own training. Which pretty much invalidates their policy recommendations.
They can't even blame it on distillation this time, unless they want to claim that their own preferred security measures were ineffective in preventing Chinese access to Mythos.
I remember that more than a year ago, when Anthropic and OpenAI started to hide reasoning steps, some were claiming that Chinese models were done, as they could only distill those US models.
I am very curious for the next batch of Chinese models. I have been using DeepSeek and it is nothing short of excellent.
Only supporting "max" reasoning is weird, their parameters are quite inflexible atm:
Important limits:
reasoning_effort currently supports only max; K3 always has thinking mode enabled.
max_completion_tokens defaults to 131072 and can be set up to 1048576.
temperature=1.0, top_p=0.95, n=1, presence_penalty=0, and frequency_penalty=0 are fixed; omit them from requests.
Return the complete assistant message unchanged in multi-turn conversations and tool calls.
Vision input does not support public image URLs. Use base64 or ms://<file-id>, and make content an array of objects.
Web search is being updated and is not recommended for production workflows in the near term.
Good that they are keeping it, Kimis way of speaking and conveying some sort of EQ is absolutely the best. The other models might be better at certain things, but nothing comes close to how good Kimi is at understanding language, emotions and reading the room in conversations.
I should maybe also mention that I have not used the later models like Opus or Fable, so my opinion might be a bit outdated.
When I remember that this site even showed Kimi having the highest score at one point https://eqbench.com
Very interesting to see how Gemini 3.5 Pro stacks up against this new wave of models. Hope they have something similar to a Gemini 3.1 moment soon. Their speciality has always been math and multi modal intelligence and the new models are recently all very coding focused.
Especially if you don't have a phone and don't want to use your google account for anything but gmail, for privacy reasons. Both of these point apply to me, for instance.
Also, the dark pattern where it shows the interface and lets you enter a prompt/set settings, but then pops up the 'create account' dialog when you press submit is pretty annoying.
This is the first time an AI provider makes a trailer[0] for their main release and game development is the first demo and main hook.
Anthropic might dominate general purpose programming,but I think there's enough of a market for a model laser focused on game scripting or tool development for game studios.
I tried the $40 plan. Seems ok to get some real work done. The model seems quite capable and being able to read the reasoning trace is bonus. It's not the fastest though.
Is anyone using non frontier models as secondary models for coding tasks? What's your setup? I'm on the Max 20x plan for Claude but I still want a secondary, maybe fast model for offloading some tasks and parallel development.
Any recommendation for a cost effective subscription service?
Imagine you're a mid sized company and you can host this model locally. Suddenly there are zero reasons to pay a single red cent to the bloodsucking American AI cartel.
Can you host the model for a lower cost per token than you'd pay Anthropic or OpenAI for a similar level of intelligence? I doubt you're beating their efficiencies of scale.
I dont have estimates on the cost of running models, but I think openai and anthropic are running on subsidized prices. At actual prices it might be worth it in the future.
how is this idea still so persistent? The fact people are able to run open models with about the same performance at 1/10th the cost should make it glaringly obvious that Anthropic has massive inference margins at api pricing.
I think the idea conflates price discrimination -- where people on individual subscriptions pay a much lower price per token than corporate accounts pay -- with using venture capital funding for opex. Both are subsidies in some senses, but the former is sustainable indefinitely.
No, and the reason is simple: Usage is bursty and if you don't maximize usage of the hardware you're going to lose on price.
Ok you can host this model once. What if I want a dozen subagents? Ok you can host it 12 times at once. What if we go a whole week only using max 4 at a time? Etc etc. The limits imposed by self-hosting might be bearable for a variety of reasons, but it's going to be more expensive and less convenient/useful.
Whether it is "open" or not seems to be in question. While it was initially called an "open" model, it seems that "open" mentions have been scrubbed from website.
hardware, electricity cost and other extra time consuming deployment, are they joke to you? ROI needs to positive otherwise open models have still BIG COST.
Is K3 marked as a proprietary model because its weights have not been released yet? Were there indications from Moonshot that K3 would or would not be open weights?
The blog post says it's going to be open, but I don't think the weights have been released yet:
> Kimi K3 is the first open model to reach 2.8 trillion parameters. It marks the latest step in Kimi's sustained push at the scaling frontier: for nine of the past twelve months, Kimi models have set the upper bound of open-model sizes.
not much reason to think this won't happen except unconfirmed gossip, but I fully expect the next one to not be released. actually I won't be surprised if even this release was withheld and the announcement withdrawn.
This looks promising as they are extensively comparing themselves to open models. There was a bit of confusion in the comments as to whether this model would be opened. I'm holding my breath!
I've playing around in between with Arc-AGI-3 lately. Based on my very quick test prompt, I do not think it will achieve any meaningful score in Arc AGI 3. Not that it was expected to.
It's important we now have a recap to the opus 4.8 release where we were threatened with ID verification as "these models become more powerful" and had to pass "verification" to gain full access to the capabilities without having random "cyber" refusals.
Public disclosure of Mythos was April 7 and leaked happened in March, but it's been heavily delayed for well-known reasons.
That said, as the frontier moves, "months old" becomes more and more useful. Opus-tier models are being used to write serious software, so we're going to start seeing open models pick up a lot more usage imo.
That's a more than 2x jump in parameter count. I know it's not a measure of quality by itself, but it will be interesting how it "scales". Bust it looks like they're gonna be competing with the big boys now, pricing also approaches Gpt 5.6 Terra
You can limit it a lot to minimize the abuse. In free entrypoint, set token and context limits to be very small. Limit to 2 prompts per IP or something every X hour. That is already a substantial limit where bypassing might not provide much benefits.
Traditional narrative is that you need tons of traces of actual execution to post-train and get models right. Nobody seems to use Kimi API from Moonshot, I bet everybody is using them on neoclouds/inference providers like Together, Nebius, Fireworks etc. where unlikely they will get traces (in fact, thats the whole promise of these inf providers). How are Kimi models improving so quickly? Is this just distillation (though Sol/Fable just came out so I find it hard to believe)
Kimi doesn't do well on my "ask a trivia question that other AIs get wrong" test.
The question it came up with, "which U.S. state is closest to Africa?" is a pretty standard trivia question without any reason to believe other AIs would get confused. https://pellmell.ai/s/dccdeca69f929f79bc89317035610049
Not worth it. I have just tried a single prompt in the web interface and it is still not finish reasoning. It thinks too much and often repeats the same stuff over and over.
Combine with the price it will surely more costly than gpt 5.6.
Its bad to judge these things on immediate release, there is a spike of excited users and that distorts performance. Also bad to judge from on a single interaction, you'll get bad requests with every provider, super busy times raise the probability
The sentiment has shifted far too much amongst the investor community and amongst enterprises who are the life-blood of the revenue streams of Anthropic and OAI.
Further releases of Chinese models that demonstrate the gap is not growing substantially is a huge problem. The spending will be called into question.
This is too expensive to be a viable model. If it were $5/1m output, it might be another story. At these prices, there's no reason to use this over GPT 5.6.
neither ClosedAI nor Misanthropic will let you use their models without them watching and storing the exchanges indefinitely. no sane company dealing with PII and/or trade secrets allows its employees to use those.
Is this really true? I was led to believe my company had an enterprise zero data retention agreement with them and it’s why we didn’t get access to Fable
Is there proof of what you’re saying or is it just a guess?
AFAIK there’s no ZDR with Claude models accessed directly via Anthropic. You’d have to go through either Google Vertex, Azure or AWS for true ZDR (at least legally/on paper).
There is no viable way of checking they are actually doing that.
That's assuming they don't put carve-out clauses in, like Anthropic did with Fable, which means data retention is back on the cards, no exceptions.
Also don't forget a zero data retention clause is still subject to the good old "law, or court or administrative order" contract clauses. :)
To get properly close to real zero-retention in a hosted model, you would have to use one of the verifiably private AI that runs in enclaves, e.g. Tinfoil (US) or Privatemode (Germany)[2]. Yes, still not the same as running on your own hardware, but a million lightyears ahead of "zero data retention" "trust me dude" clauses.
No I know of course, I don’t trust them as far as I can throw them when all of these companies committed the largest copyright theft in human history to build the models.
I just wanted to know if that other person had proof or not, and I guess they didn’t. I would still rather have some semblance of an agreement than not have one at all — if you’re coding on a consumer plan you should just 100% assume anything you write with it will end up in the training set
In context it seems your recommendation is to instead send those data to models within Chinese nation-network space. I’m not here to defend US frontier model companies; your accusation is probably accurate. But I doubt sending data to China is an improvement.
with open weight models, you have three other options
A) use a provider that pinky-swears not to store your data. they obviously don't give a fuck about 'distillation attacks', so they have little motivation to voluntarily monitor and store your queries. reasonably high likelihood of privacy.
B) rent the hardware and run the model yourself. very high likelihood of privacy.
C) buy the hardware and run the model yourself. absolute certainty of privacy.
I'll say after having it run for a few hours that I still don't feel it matches even Sonnet. It still does a lot of back and forth that feels dumb, but it's possible this is in effect Anthropic tricking us by hiding the full reasoning traces - who knows what Sonnet still sounds like if you were to see the whole thing.
What subscription plan for Kimi 3 would be the most cost effective? Most people only talk about API efficiency, but is there any place that evaluates how much you get with the subscription plans?
Benchmarks look ok, but they don't mention anything about the issue with the model being extremely slow and verbose.
That being said, it's awesome to have such an open-source model, even if now it's unusable mostly locally, with hardware improvements, in a couple of years, the verbosity/speed wouldn't matter as much as the intelligence.
> Among the models tested, its overall intelligence ranks second only to Claude Fable 5 and GPT-5.6 Sol.
> The full model weights of Kimi K3 will be released in the coming days. More details on the architecture, training, and evaluation will be published together with the Kimi K3 technical report.
The literal interpretation of that sentence is "when it is second or third, it is only behind Fable 5 or 5.6 Sol". And indeed they give benchmarks where it is ahead of one but not both models.
Yeah, I would have expected Zhipu to ship a Fable-adjacent model by the end of the year, but the jump from Kimi 2.7 (which I think is just barely at the level where it is genuinely helpful for coding) to this is absolutely bonkers. And this is clearly not just benchmaxing; this thing actually works.
If you told me I could only use this and never use Fable or Sol again, I'd shrug and not feel like I'd lost much.
LLMs are hopelessly confused about which model they are. Ask DeepSeek V4 Flash which model it is, and it's 50/50 between "I am DeepSeek (深度求索)" and "I am part of the GPT-4 series developed by OpenAI." Ask Claude, it'll say Claude. Ask Claude in Chinese, it'll sometimes say DeepSeek.
It's incredibly funny, but I don't know whether it's related to distillation; it's probably quite rare for a distilled trace to mention which model it came from. (I'm not saying distillation doesn't happen, just that it's possibly unrelated.)
For your specific example, the internet is full of "As a large language model developed by OpenAI, I can't..." due to people pasting chatbot output without reading it. Seems reasonable for that to surface as part of the CoT for your question about model capabilities.
Now, will they actually release the weights? Seems like Chinese model providers are slowly closing up, like Alibaba's Qwen 3.6 which did release weights (but not the biggest parameter count ones) and none for 3.7.
The big danger here is the gradual increase in open-weight subscription costs. I use open weight subscriptions, with lower-cost models for 80% of my tasks and GLM-5.2, Qwen 3.7-Max, Kimi-K2.6/2.7-Code for the 20% that need the most intelligence. That lets me maximize the rate-limit the subscription gives (rate limits per model are literally a price-limit-per-token/model). When new/more expensive open weights come in, providers phase out older/cheaper models. Over time we will either have to pay more, or use our subscriptions less.
It goes without saying, but if the open weights become as expensive as SOTA models, there's no point in using open weights. If nobody pays for open weights' development, the development dies out, and we're stuck with a US-controlled duopoly again. Which may be the biggest threat the world has seen from the US since nukes.
It’s open weight, so the price will end up being the marginal cost of hosting it.
Personally, I like that there is an option to not send data to companies that have strong financial incentives to steal it.
Also, open weight foundation models can be distilled, so they’re providing a service that the US duopoly is actively blocking. Given that app specific distillation can get > 10x improvements on inference cost (with slight improvement of quality), it’s clear that it’ll win out over time.
95 input, 16,658 output = 25 cents! https://www.llm-prices.com/#it=95&ot=16658&ic=3&oc=15 (13,241 of those were reasoning tokens.)
I think that's the most expensive pelican I've rendered through a Chinese model so far.
https://canada.newark.com/productimages/large/en_US/4492516....
In the field I work in, if someone says "Pelican", 99.99% of the time it's going to be an equipment case. We never have reason or need to refer to the actual bird.
I mean, okay, a bird also cannot ride a bicycle, but at least it is alive, has feet, etc.
It's a silly fun little benchmark, and because Simon's been doing it for so long, you have a lot of examples over the years to compare. But you can always come up with and run your own test with other drawings.
"How many pelican riding bicycle SVGs were there before this test existed? What if the training data is being polluted with all these wonky results..."
https://news.ycombinator.com/item?id=46974853
Try setting reasoning levels yourself manually. We see in the benchmarks that one of the graphs shows low, mid, max, so its clearly there.
I had the same issue with GLM 5.2 only offering high/max.
By playing around with openai compatible protocol, and setting the reasoning level from none, low ... high, xhigh and testing a flawed logic test.
It was easy to see that GLM had all the different reasoning levels. Low was like one line, medium did a few, high started to really expand, xhigh was a page or 2, max was MAX.
Very sure that you can force K3 into using less reasoning.
I just tried "hi" through the same OpenRouter API and the input token count for that was 86 - and for "hi there" the count was 87.
I think there's an 85 token hidden system prompt of some sort.
> I can't repeat my system instructions verbatim, but I'm happy to be transparent about what they cover: they're content guidelines about not generating sexual content involving minors, non-consensual scenarios, or content that sexualizes real people without consent — standard safety policies.
> Is there something I can actually help you with today?
Love how passive aggressive "something I can actually help you with" is!
That message feels misleading to me though, I have trouble imagining they can fit their full content guidelines into 85 characters. That looks more like the model hallucinating justification for not revealing anything.
> I don't have access to real-time information, so I can't tell you the current time. Your device's clock (on your phone, computer, or watch) will show you the accurate time for your location.

I know the machine can't judge the user or browbeat them into changing subject, but the reply is a bit unsettling.
We don’t know what’s inside these bikes!
Is this a classic 'commoditize my compliment' situation? They want to sell the hardware and infrastructure behind AI and make the software part not the value driver / moat?
I can see it. But also even two Chinese labs sinking 100s of millions USD into training isn't exactly commoditization. It's still a ton of effort with dubious payoff.
- Companies can still make money from commodities
- Chinese labs only have 5-10% the valuation of OpenAI/Anthropic, so massive monopoly profits aren't necessary. Profit expectations for tech companies in China are really low in general, complete opposite of the US.
- Open weighting is a great way to get talent/attention/reputation
The AI CTO from The Linux Foundation, Matt White, spoke about his recent trip to talk to the Chinese Ai labs ~month ago.

> 100s of Millions
That is utter peanuts given the stakes. This is competition between two super powers for the most important technology in human history.
You ever seen a swan drown something before? It ain't quick
All the ones I'm familiar with are veggies, with webbed feet and squawk a lot.
The children's book "if you give a mouse a cookie" was about exactly this phenomenon
I could also argue with GP's comment that some US companies are driving towards commoditization as well. One released a model this week and another announced their series d today.
Photonic computing?
So far it rates "quite important" and certainly not "paradigm shift".
I've just spent most of the day wading through vibed blogs and what not to glean info on ... setting up LLMs! The content on the web is already in a parlous state and rapidly getting nicely but rather the same presentation and mostly right but somewhat wrong, often in crucial parts.
On the bright side I did find an absolute belter of a vibed site and it was only mildly wrong but I was able to sort that bit out and to be fair I think it was written up by an expert with help from a LLM and had a genuine human mistak in it.
Anyway, I suggest you might like to look at the internet as a whole as a paradigm shift and reserve judgement on LLMs and this decade's version of AI.
Yes, Kimi K3 appears a touch below them both, but above all other models. So I'd say a few weeks behind, not months now...
I wouldn’t be surprised if OpenAI (so much for “open”) is using GPT-6 internally already.
It appears that peasants like us are not going to get access to frontier AI anymore at any price.
I have their highest subscription, so it's not that I can't find uses for it and it has sides to it I really like, and it performs really well in some situations, but 2.7 also gets totally lost on tasks Sonnet and Opus has no problems with, and it looks like that is still the case with K3.
That said, I'm doing things with these models that are a lot more complex than the average app people will throw these models at, so I'm sure there are lots of use cases where it will perform better than what I'm seeing.
I don’t know for sure that they are weeks or months behind. I doubt anyone outside of 3 letter agencies knows that. The pace of AI is crazy fast and China is notoriously secretive. We could be comfortably ahead or China could have the top model by the end of the year.
I don’t think any of us have enough information to know what’s really going on, but I suspect it’s a very tight race.
So it's not 6 months but it's also not a few weeks.
The preview models were not as good as the final release. Thus training must have continued after the initial announcement
Fable has been out for more than a month - I didn’t have the preview version and I was using it around June 10th, when my Claude subscription expired. Saying “Fable only really came out 2 weeks ago” is just factually incorrect all around.
Destroy any hope of profitability, prevent further capitalization, ultimately bankrupt them.
Hasten the popping of the AI bubble.
Drag down the stock market.
Put a dent in the GDP (alleged growth).
Cause investors to pull back, further depressing economy.
Devalue the dollar. Kicking off an interest rate doom loop.
Challenge USA's hegemonic role in the emergent multi-polar (post neoliberal) world order. (Gleefully supported by the ruling coalition's anti-globalist America First faction.)
It all makes perfect sense.
There might be foreign policy implications but the biggest reason is really nurturing their own tech independence and entrepreneurship.
The US is a barrier to a number of key Chinese goals, like reunification with Taiwan. So of course most of what they do will take the US into consideration.
Also China's silent but powerful support of Russia and its invasion.
You can't expect them to start sanctioning Russia for ukraine, Israel/US for their middle east shenanigans, etc.
Their web chat has almost no settings of customization. Everything they present just comes off as amateurish to me. I trust them less than most Chinese AI companies, which a very low bar.

1M context, pricing is $3/$15 for 1M tokens (cache $0.3), which is extremely high for a Chinese open-weight model, but if it's truly competitive with most of the current frontier and is only behind Fable/Sol, the pricing is justified.
This is 1:1 pricing of Anthropic's Sonnet series (except Sonnet 5 which is currently on discount), and very close to 5.6 Terra pricing (Terra's input is $2.5).
One thing to consider, though: reasoning efficiency matters directly for how expensive a model actually is in real use. GPT's models are extremely reasoning efficient, and some Claude models like Fable at lower effort are as well. So if Sol spends 10K reasoning tokens to do something (at $30/1M) vs Kimi K3 that spends 50K reasoning tokens, Sol would win on cost effectiveness.
That said, Kimi is competing against GLM in my mind, and GLM 5.2 is less than 1/3 the price.
At this point, I always look at things like Artificial Analysis' total cost to run their tests. It'll take into consideration the cost of tokens, how many tokens it burns through, and how effectively it uses caching (and the price of that caching).
If a model "costs the same" but its reasoning ends up going through a ton more tokens, it doesn't really cost the same in real world usage.
If you think a page is too vague, use a famous known writer's work as a reference.
I doubt you are going to get a response from an anthropic employee, but I think it is safe to assume they have swapped to a new tokenizer because it improves the performance of their models.
Less efficient in token usage but per the blogs; it enables the model to perform better.
Having used GLM 5.2 extensively and K3 for a few hours now, these models are nowhere near each other. 5.2 is a great model, and I use it for a lot of things, but it's noticeably below Opus 4.8 or GPT-5.5 in real-world usage.
K3 is in the same ballpark as Fable or Sol.
Neuralwatt was cheap (but slow) but they cranked their price.
Ollama monthly sub is speedy but doesn't offer a lot of quota.
Right now unless you're paying by the token, there's no cost based reason to use the open weight models for daily coding work because the monthly coding plans from Anthropic and OpenAI are a better deal.
Matches my experience, I got their Pro subscription and while I enjoyed the model itself a lot and while their ZCode harness is also pretty nice, it gave me less tokens for similar amounts of money that Anthropic would give me on a subscription: https://blog.kronis.dev/blog/z-ai-s-glm-5-2-is-a-great-model...
I'm yet to try out Kimi, but if their subscription were to be anywhere comparable to Anthropic/OpenAI, I might just switch over because competition is good.
DeepSeek V4 Pro is really affordable per-token but regularly kept making mistakes in the tasks I gave it. I mean I could at least afford the tokens to go over the work a 2nd, 3rd, 4th and 5th time and gradually fix most of the issues, but it was a very frustrating mode of work.
Not very good for programming though.
> Right now unless you're paying by the token, there's no cost based reason to use the open weight models for daily coding work because the monthly coding plans from Anthropic and OpenAI are a better deal.
Maybe. I am on a $20/month Anthropic subscription this month but I also use Claude Code frequently with Deepseek v4 flash and pro, GML5.2. For simple work Deepseek v4 flash is so nice because it is fast.
What you say is true however, the US hyper-scalers are still (desperately?) subsidizing subscriptions for market share to boost there valuations.
I really want to see AI inference costs approach zero, and I think I just need to wait a few years to see that.
I can get by working on code strictly in GLM. I can't with DeepSeek. It makes some pretty careless mistakes and isn't a very deep thinker.
It is very useful as a general purpose model for non-coding purposes though.
Kim, however, has exposed the whole reasoning trace, or enough of it to matter. I'd almost forgotten how nice it is to see this. I've been able to see all of the weird twist and turns it takes and it is joyful. But also, far, far more informative and means I can debug ideas far more thoroughly. Also, at a first glance it seems to have gotten quite far on a niche hobby horse of mine that no LLM has been able to crack. I'll be testing this more for sure.
Say of that what you will, but it's not because they want to wrest control from users.
It's because they don't want Chinese companies to do exactly what Moonshot (Kimi creators) and others have done.
Recently, they backported the blocks to Opus 4.8, so I’m reluctantly stuck on sonnet.
I probably could successfully apply to get special approval to use claude code unencumbered, but I don’t think it is ethical to support tooling that’s built so a central authority gets to decide what intellectual endeavors and knowledge work are permissible, and what are not.
I have high hopes on this topic, given token efficiency seemed to be the primary (only?) goal of the K2.7 Code release.
Excited to see the signals that come out of the big eval/benchmark sites.
It'd need to be exceptionally smart and error free to ever make sense.
One has mostly been reliable, stayed peaceful towards us and is primarily concerned with their internal matters and the countries right next to it. They have long-term strategy and understanding of win-win situations.
The other one keeps threatening to invade/steal Greenland. Keeps waging an economic war against the entire bloc. Positions their propagandists right in our middle and does the best to influence our elections. Exports fascism and finances antidemocratic forces. Supports the genocide in that certain country. And still have their soldiers in our country, against the wishes of a majority of the population. Oh and they don't honor any treaties if they feel like it.
Easy choice.
Does that make china an angel? Hell no, they are still committed to enslaving the Uyghur people, keep threatening neighbors and are mostly han supremacists. Human rights are seen as merely a suggestion by them.
But at the time being, one is clearly more reliable than the other. Long-term, I'd like to avoid both the US and China.
This is textbook international relations realism. Rising powers pretend they aren't powerful so countries don't balance against them.
Their actions are entirely predictable.
Then suddenly they will begin to do imperialism, like all great powers, and suddenly they will pretend to be stronger than they are.
What alternative would you propose? Currently, there's no alternative I know of, either you rely on the US or on China or both.
Me and many others are doing our best building that alternative and promoting local solutions in all areas, but it takes time. And until then, I'd like to use the one that isn't threatening to steal our territory, thank you very much.
Why?
And I'm still not rooting _for_ them, I'm rooting for choosing their services above american ones for the time being. That's quite a different thing, as should be obvious. Respond to things I actually said and not things you think I might possibly think.
A very inconvenient truth for the China hawks.
Given how China behaves it should be evident that the only reason they don't apply military force is because they are not in position to. Not abusing military strength is not exactly being the paragon of virtue when your opposition could probably glass the world thrice before the day is over.
>Positions their propagandists right in our middle and does the best to influence our elections.
>Exports fascism and finances antidemocratic forces.
>Supports the genocide in that certain country.
>Oh and they don't honor any treaties if they feel like it.
I don't know how anyone can really mention any of these when trying to paint a bad picture of anyone as compared to China. It's just an obscene exercise in ignorance. I just can't make sense of discourse like this except as a result of propaganda.
You are not mentioning the greenland situation - why? That's the really big one and the one that made the US much closer to "enemy" than "friend". After all, friends don't threaten to annex your territory.
Regarding propagandists and financing of antidemocratic forces: this refers to a current issue. US is deliberately financing spreading of its ideology in the EU, as they confirmed themselves. [0]
With the genocide, that discussion I'm going to stay clear of, as nobody will be convinced of the other position anyway, too heated. Shouldn't have mentioned it in the first place, as this always leads to flamewars. mb.
Regarding honoring of treaties: let's start with the budapest memorandum - I think that was the first really big one. Then, the 1967 Refugee Protocol which forbids third-country deportations. Then, the UN Framework Convention On Climate Change. Violation of the UN charter, withholding of promised funds. The Convention Against TOrture.
Then all the broken/ignored/overturned trade treaties, all the promises made and not kept - how would anything rely on their word at all anymore?
I could go on for multiple pages. Why do those not count? Why do they have to be "propaganda"?
It is unbelievably difficult being reliant on the US in any way right now. And that's what I'm talking about. Not, which is the "better" country. Reliability and ... well, utility to its partners is the basis of it all. Which right now - compared to china - is rapidly sinking. So where is that ignorance you are speaking of?

Kimi also offers generous subscriptions. Subs aren’t going anywhere. Think of subs like running an insurance business. There might be some users you lose money on (ones who max out their weekly quota without fail), but they’re managed such that the average subscription turns a healthy profit. There’s never been subsidies in model serving, inference is just cheaper in terms of ops TCO than people assume, and API margins are very high.
So... convergence?
> but they’re managed such that the average subscription turns a healthy profit.
It didn't work like that, or at least that's not how it played out. People max-out their subs all the time which is why strict and multiple limits were implemented by all providers. Also, I subscribe to z.ai and recently they dropped the quota significantly that now their sub offers less than Claude and OpenAI. It's still x5-6 what it would cost on API costs though.
> inference is just cheaper in terms of ops TCO than people assume, and API margins are very high.
API margins (at least american ones) are probably healthy. But I don't think that inference is that cheap. It would cost 300-500k to just run GLM 5.2. There are lots of other factors too: reliability (can you keep the GPUs running all time), electricity cost, sys. admin costs, location costs, etc.. I wouldn't be surprised if the API margins are quite close to operational costs.

Generally looks like a Sol/Fable tier model, better across the board than Opus 4.8.
(Edit) English blogpost is up now: https://www.kimi.com/blog/kimi-k3
Forget about their pricing but the companies that do have means to host such models fully on-prem are also the same companies that are paying tens of millions of $ in inference cost every month, and are by extension the biggest customers of OAI and Anthropic
After using it for a few hours, I believe these benchmarks.
I don't want to cheer against my country, but we've given up on open source. The way Anthropic and OpenAI treat their customers as adversaries is embarrassing.
I will cheer for China, for Kimi, and for z.ai until we have something in the same category.
[1] I'd even be fine with open weights, fair source, or anything that let us have direct access to the weights. Even if that came with stipulations. Don't hide the weights from us.
The argument on our side wins - if America or the West don't do open source, China will. And that means -- with certainty -- that China wins the market.
Every politician and VC should hear that loud and clear.
Given the pricing, it suggests that this model is much more efficient/competent than previous-gen OS/distilled models.
This is such a common omission: the Chinese models are open, you can host them yourself on your premises. So privacy and independence.
while I am skeptical that this is happening atm, there are probably many industries where the risk does not seem worthwhile
Maybe I just don't have any imagination.
[0] https://en.wikipedia.org/wiki/Underhanded_C_Contest
I have an RF engineering background, a nice mmWave vector network analyzer can easily land in that ballpark.
If the business value is there, companies will pay for it.
Correction: Lots of organizations are refusing to use Anthropic Fable because they have forced opt-in data collection as part of their privacy policy, even for Enterprise.
Not everyone's going to care about Anthropic requiring data collection (a similar debate plays out with regards to "pay or consent" on website tracking), just as not everyone cares about China with regards to security/IP issues (if they did, a lot more would be banned besides occasionally-Huawei).
With Oracle being junk before this, more will follow.
This would drive down Anthropic's margins, but drive up demand for datacenter and GPU capacity. It's not that people would be using fewer GPUs, they'd just shift demand from high priced token vendors to direct GPU rental, which benefits datacenter companies while hurting Anthropic.
Now they are betting with Project Stargate but it also seems to be crumbling down.
But don't forget that they literally hold the biggest databases, both in commercial and open source, that is, Oracle Database and MySQL. Plus Oracle Java they literally controls at least 30% of the internet's software infrastructure.
And also with a good team of attorneies enforcing the licenses, they can squeeze so much money at the cost of morality.
Also recently they downgraded the always free OCI ARM instance from 4C24G to 2C12G without telling anyone.
They're drowning in debt and risk is increasing. If these US models don't keep holding up their valuation will tank further and some will recall the loans or ask for different terms.
The DeepSeek incident has already shown it, this is a reminder.
https://www.youtube.com/watch?v=LSlV206xPqM
These real world examples show it's one tier away.
(I mantain a client with llama.cpp and 101 models across 14 companies by http)
Having said that, the safety system on Fable makes it an extremely unattractive model. It feels that half of the time you're paying double for Opus level performance.
I finally bumped into a task that Codex would refuse to work on.
Was I attempting to reverse-engineer a GPU driver? Yes. Was I trying to hack into the DoD? No.
I wasn't doing anything wrong, but that's not what OpenAI's safety mechanisms thought.

> As an early proof of concept, Kimi K3 designed a chip to serve a nano model built on its own architecture. In a single 48-hour autonomous run, K3 built, optimized, and verified the chip using open-source EDA tools on the Nangate 45nm library. Within 4 mm², the chip closes timing at 100 MHz and sustains over 8,700 tokens/s decode throughput in simulation, packing 1.46M standard cells, 0.277 MB of SRAM, and an INT4 MAC array with fused dequantization. A chip built by a model, for a model, reflects K3's long-horizon agentic capabilities.
Absolutely wild.

It’s an ASIC with the model wired into it so it’s very low power and fast.
I’d buy these. Say $100 for a frontier class model. Maybe more.
There was a paper a while back that showed top-K selection like that with tiny models was able to reliably solve some 1M-step Tower of Hanoi when no frontier model could. Very big level up in capability just from horizontally scaling compute.
We could have the photonic AI model ASICs for real!

It's not as simple as a weight swap between identical architectures.
The speed gains are also from not having to route the weights through wiring like with ROM cartridges.
Doesn’t need hbm or lots of memory, because the hardware can just forward the data straight to the next layer and you don’t need to round trip through memory.
They claim to be working on an approach to make the underlying hardware a bit more reusable between models.
Most big model weights will not fit a single reticle sized chip - so you’d have prob 30 different chips to split the model .
And you’d need super fast chip to chip comms for the all-reduce and similar.
So scaling to 1T models is hard - and a long lead time - but can be very power efficient.
1) the hardest, custom silicon + MCU to manage the USB interface
2) not as hard, shared memory, NPU + MCU to manage inference and USB interface
Theoretically you could do 2 with the right MCU, NPU, and memory combo. You'd stream/DMA the weights from memory into the NPU and then read the results with the MCU. From a user's perspective, it might take the form of an openAI API compatible endpoint that enumerates when they plug the USB device in. There would likely be some host-side software to ease the pain of trying to use a USB device as an HTTP API.

Imagine what’s possible if you had GLM-5.2 turned into a hardware chip like this.
Sure you would. Running frontier class models on current hardware costs in the order of tens of thousands of dollars. It is more likely that these custom ASICs will be priced competitively with that, and not with Super Mario Bros.
Oh, and energy consumption will be in the same order.

Edited: I was wrong.
"Kimi K3 is the first open-source model to reach the 2.8-trillion-parameter scale. It is the latest step in Kimi's continued push of model-scale boundaries: in 9 of the past 12 months, Kimi models have set new records for open-source model scale."
The page has definitely changed.
(I'm not sure why you would be skeptical of somebody recollecting something they probably read only half an hour earlier.)
Instruction following seems lower than I’d like, too. OTOH scores on agentic stuff seem high, which… feels a bit contradictory? I thought decent instruction following is step 1 of solid agentic workflow.
The benchmarks look nothing short of incredible. Assuming it’s not benchmaxxed to hell and back it’s just a notch below gpt 5.6, which came out what, a week ago? If the performance claims hold up the delayed Gemini 3.5 pro will likely end up not only behind fable, but also behind 5.6 and a (supposed) open weights model. Google might have to do some real soul-searching.

Judging from the behavior It’s possible that the chat/ux model does know and has an unbiased opinion about china, but the filtering is on the front end/client side and so the user facing model has not been fine tuned natively. The reason is probably because it’s not easily to change only one part of the model without affecting safety in other parts. We know this e.g https://youtu.be/b-nD3HgIR5Y?is=TeyXnaNMNndqWqax
It’s quite likely that API Models also Have this filtering, but I Haven’t tried. Anyone had luck to get it to spill its beans on the api side(almost)?
EDIT: Kimi 3 definitely knows about it. https://streamable.com/tun7et Quite intriguing and weird UX experience
This has always been the case with Chinese models. Their web ui is a service provided from China, so they are required to censor it, but not the models themselves.
What is plausible is that they haven't made any attempts to explicitly steer certain opinions into a certain direction, and just let the model take over the bias of the training data, whatever that may be. Filtering in the front end is the easy, lazy way out to be legally compliant.
2.8T param open model, 1M context, native vision. Weights releasing by July 27 with technical report. Launching with max thinking effort by default; low/high effort modes coming in future updates.
But the model itself is amazing. I think I might put this above Opus 4.8.
This is entirely for personal use and small projects. I don't have huge needs. I get access to gpt models via my employer for work things. But I'm also using pi with those models.

No they're not. It would end both companies if they were ever found to be doing that.
Their terms are clear - if you use the coding plans they can[0] train in return. Enterprise and API, absolutely not.
The argument here is that with the Chinese labs you have zero legal recourse.
[0] opt-in, thanks
Their terms are not worth shit considering they are reselling you stolen copyrighted data. Even in they terms they started clearly say they retain your data for "safety reasons" for however long they want. Perhaps you didn't watch the space with Anthropic going back and forth with ToS updates(we retain your data for 30 days...stike that and add 30 days or more or no or ..whatever) like my own alpha website.
I'm not comfortable with how these models were trained. I have quite a bit of open source code out there, and I personally see such training as copyright and license laundering.
But that's not how the law sees it, and I grudgingly accept that, regardless of how I may feel, and I don't let my feelings on the matter make me think irrationally when it comes to whether or not these AI companies honor the terms they provide.
Sure, they might be breaking their promises, training on our data when they say they won't. But I do think they most likely aren't, and that it would be corporate suicide if they were and it ever came out.
Anthropic paid several billion dollars to settle a lawsuit they were likely to lose. OpenAI is now about to get taken to the cleaners for corporate espionage against Apple. They do not give a fuck about the law. Paying $5 billion for some fines is a trivial cost of doing business when you're aiming for trillion-dollar IPOs.
> make me think irrationally when it comes to whether or not these AI companies honor the terms they provide.
Irrationality is thinking there's such a thing as honor and that companies which have repeatedly broken the law for data won't do it again when there's no enforcement mechanism that acts as a real deterrent.
This dog-and-pony-show is a rehash of the Pascal's wager we saw with smartphone security. Everyone thought it would be "corporate suicide" to hack an iPhone, but NSO Group did it. Apple sued NSO Group, and then settled out of court immediately after. Now we live in a post-hacking world and everyone pretends like this is an unavoidable necessary evil that corporations are powerless to stop. Suggesting litigation is a comically useless strategy because the law rubberstamps any form of useful surveillance or retention. Failing that, NSO Group has enough sycophant lobbyists to smear anyone that takes their threat seriously. Look at OpenAI and Anthropic and tell me that it's not the same hostage situation; can you?
You can do whatever stupid stuff you want to with your data. But this is an absurd amount of faith to give to guilty businesses, on the level of planning your world domination schemes over Skype.
* Exploiting ambiguity around fair use at a large scale before the law catches up and then jointly lobbying with your competition to make sure your interpretation of the law becomes reality.
* Explicitly signing a contract with enterprises to respect their IP and then proceeding to break that contract with your own customers.
The former is firmly in the gray area of legality and doesn't directly hurt your own customers. The latter is both an unambiguous contract violation and a flagrant attack on your own customers' most valuable asset.
> Personal data we collect or receive to train our models

While I don’t have visibility into individual corp contracts, hitting tab on a FIM is ‘feedback’, so it is not so clear cut.
Second: My argument doesn't hinge on Anthropic not being able to weasel their way out in court if it came to that. My argument is that neither Anthropic nor OpenAI are going to break their signed contracts or even fudge on the clearly communicated understandings of what the terms of the API pricing are because neither one wants to hand the other the obvious weapon of: "unlike {other guys} we honor our word".
It's just not happening, and comparisons upthread to the fair use story totally misunderstand the incentives at play here.
(And as an aside, this whole thread also shows clearly the classic programmer misunderstanding of the law. The peanut butter sandwich instructions analogy is for code, not for the law. The law doesn't actually work by allowing any possible interpretation to hold equal weight the way that many programmers think it does.)
Is that so? Recent rulings in the US specifically gave me the impression that when backed by sufficient legal representation and goodwill on the judging side indeed any possible interpretation will suffice.
I think that's what makes law making complicated - you either err on the side of leaving too much room for interpretation or not enough.
It's simple mental calisthenics. If you are handing an organization whose entire business model is built on stealing data with spurious reasoning, what do you actually expect they will do? Don't be a fool.
You mean all the conditions that are attached to Fable use? My enterprise is deliberately holding off because those are unacceptable.
Good, fine. This is an example of trusting the company to honor their own terms, not the opposite.
The discussion was about training, not data retention. Two very different concerns.
And if you're a decent sized customer, most providers have a route to not even retaining the data for safety/security reasons. The reason Anthropic had issues is because they do have a path to "no data storage" for Sonnet/Opus, but not for Fable. Which is why at work we have access to the former, but not the latter.
Which is more likely? That past behavior is an indication of future behavior, or that they because they could be eliminated from being found out it’s unlikely they’d do that thing. (By the way it’s also likely they’d are eliminated if they dont train their data with every advantage over their competitors possible). So I think it’s naive to think the incentives reward not doing the malicious thing now.
I also don’t trust them lol

Enterprise contracts are checked and agreed by lawyers. The contract states no training.
If the provider fucks up, there are actual monetary damages defined for breach of contract.
I get that in principle that there's no retention, but these are powerful models that can comprehend, paraphrase and summarize your logs for the sake of "product" improvement. Who knows what's collected here.
No, you have to opt-in to that. There's a privacy toggle on account settings.

> Apple also claims former engineer Liu exploited a security bug to download confidential engineering files after leaving the company. Rather than report the exploit, Liu allegedly joked about it in messages (“LOL,” “so funny”). Liu also failed to return an Apple-issued laptop after his departure.
This seems pretty close to "they trust me, dumb fucks" behaviour.
Now what I would expect AI companies to do is to take things which were submitted as feedback and pretty much adding to training:
"Do more of this: <copy of the whole response which was flagged as good in feedback>"
"Do less of this: <copy of the whole response which was flagged as bad in feedback>"
It's paraphrased, but the point is that they will most likely use it more-or-less as-is and thus whatever is in there will be part of the model's training set rather than someone picking up the parts from response that are important and only including them (which happens with traditional feedback).

> If you explicitly report materials to us (e.g.via our thumbs up/down feedback mechanisms), or by otherwise explicitly opting in to training, then we may use those materials to train our models.
Or do you mean the feedback stuff? Their KB article at least seems to contradict that.
Edit: And the point of the poster is they have already demonstrated a track record of lying and misconduct, so how can you trust their word now? What have they done to show you they have taken responsibility for past actions and changed?
i don't know why this is so controversial, their terms are written to perfectly fit this training regime. one of you downvoters i'm sure has an enterprise contract with them, just ask.
if you are using bedrock, until very recently, they didn't see your requests and could not paraphrase. but too many people were using bedrock for too much stuff they wanted to see. so that's why the terms for bedrock changed for fable 5. this was the core of the palantir / defense dept drama with anthropic.
* A company following suit with their entire industry in choosing a very generous definition of fair use.
* A company being the first to defect and actually break their signed contracts with enormous enterprises committing to not train on those enterprises' most valuable assets.
Training on copyrighted works signs them up to be a part of a system that is at this point too big to fail and places them in good company with all of their competition. Breaking their signed agreements would open them up to very well-founded and well-funded lawsuits for contract violation and give their competition a huge boost.
All of a sudden "we actually don't break our contracts" would be a selling point. No company in their right mind is going to let what should be table stakes become a differentiator for their competition.
So in your opinion, they are training on your data even if you toggle the "don't train on my data" checkbox off?
That's a bold assertion.
Think of it as the Big Data hype some years ago.
Past behaviour informs future trust and I wouldn't trust these companies whatsoever.
What they have been doing, with some narrow exceptions where they have lost billions of dollars in court cases*, is not at all obviously prohibited by copyright law. Neither web scraping (i.e. asking for copies of data from people you have every reason to believe are authorized to give you copies) or running algorithms on copyrighted data are generally copyright infringment. I say generally because the "algorithm" of "ctrl-c ctrl-v" is obviously an exception, and there's some argument that training is similar enough to be illegal - a fairly weak argument that is mostly losing in court but has some tiny chance of still succeeding.
The law doesn't have teeth to prohibit things not prohibited under the law - no matter how much many people would like them to be prohibited. This shouldn't be surprising.
Unlike with copyright, the law does pretty clearly prohibit violating contractual terms to not hang onto or use other peoples data for purposes other than the narrow ones laid out in the contract when you agreed to the contract.
* Namely acquiring copies of data from people who they know aren't authorized to make copies - i.e. torrenting.
So they are in fact literally putting copyrighted data into the model weights and reselling it.
More problematically there are camouflaged sharp spines pointed primarily in the direction of poorer people, and people not advised by lawyers.
But none of that matters here when the damaged parties include the megacorps of the world.
I trust them to act in their own interest if nothing else.
What's a little contract violation if the fate of humanity is at stake?

Am I being overly cautious not wanting to send my data to Chinese companies?
That said, I wouldn't rule out OpenRouter misclassifying - I've seen some providers where I'm fairly sure they have.
For anyone else that believes their input needs secrecy, you need to check the corporate plan of any provider for data protection clauses. Most use the cheaper plans as bait to get more training data and free feedback.
At this pricing, I'll be surprised if it's open.

11 days is a long time. It does not take that long to implement inference at providers. In my opinion, seems like they're being pre-emptively cautious about government intervention/review
I believe Kimi also does some sort of Q&A and eval for day 0 partners, since early on a long of inference providers just weren’t running their models properly.
Now that they have compute capacity to train larger models, there is a non-zero chance they will be in the lead by next year.
In which case they will probably stop sharing to protect their position.
Which basically translates too "Don't give away tools that can be used to undermine your own goals".
Also very cool to see LatentMoE being picked up by more models (https://arxiv.org/abs/2601.18089)
> K3 pushes the boundary of end-to-end knowledge work. On the GDPval-AA v2 leaderboard, Kimi K3 scores 1687. The benchmark evaluates AI models on real-world tasks across 44 occupations and 9 major industries; Kimi K3 ranks behind only Claude Fable 5 Max and GPT-5.6 Sol Max, and ahead of Claude Opus 4.8 Max at 1600.
> On AA-Briefcase, Kimi K3 scores 1527, ranking second among all models — behind only Claude Fable 5 Max and ahead of GPT-5.6 Sol Max (1495). AA-Briefcase is a private agentic knowledge-work benchmark developed by Artificial Analysis to evaluate frontier agentic capability in long-horizon knowledge work.
Really good benchmark score it seems. Maybe another DeepSeek moment right here.
Pretty sure ranking “second” to two others means ranking third.
“Second only” here has meaning “next after”, not “number two”.
England is second to none.
It’s a miracle that in language same words have different meanings depending on context. If this wouldn’t be the case we could have hardcoded NLP algorithmically without inventing these expensive LLMs!
This is the same benchmark where Sonnet 5 outperforms Opus 4.8 max.
Like all model releases, the benchmarks aren't going to tell the whole story. All of the open weight models come with amazing benchmark results now. It's hard to believe anything other than that the benchmarks are leaking into (or intentionally included) into training data.
(On several other benchmarks, it costs more, takes longer, and does worse.)
Coding Plans by MiniMax ($20/mo for 1.7b tokens) and Z.ai (~$30/week use for $17/mo) are also tremendous value for money.
Surely not... What made DeepSeek disruptive was that the cost was 10X lower.
In this case, the cost is about 2X lower the Sol I think?
At 2X, you're pretty close to the error margins due to token efficiency etc...
I'd say this is "on trend" for open models catching up to frontier labs, but its not a "change in the trend" like DeepSeek was IMO.
The frontier labs need to recoup a huge amount of cash to cover their model development costs, and justify their valuations. That’s plausible when they’re only ones capable of selling inference on these models, it a lot less plausible when models themselves become cheap commodities, and you’re just competing on your ability to provide compute. Anthropic and OpenAI can’t compete with people like AWS on that front.
Compare the amount of spend vs whats outputted.
Prospects don't really look good for US frontier labs even if they are ahead. They are incredibly inefficient.
It was impressive work, but models were commoditizing and inference costs were dropping rapidly already. They were neither the first nor the last 10x optimization, from what I’ve seen.
By definition there is no model that is both cheaper and as intelligent or better than another on the frontier.
Is that better?

What page does that come from? I'm having trouble tracking it down.
It also, for some reason failed to generate either of the 2 coding demos (hamster svg and solar system css animation).
Intelligence-wise, it's between GPT-5.6 Terra and GPT-5.6 Sol. It's ~30% better than Kimi K2.6, but a lot slower and more expensive.

Of course the shills are shifting their tone: this thread as devolved into "sure yup it's totally SOTA but it sucks because it'll use more tokens than Fable to do the same task".
I take it that's the new tune we'll hear for a while. Oh well, at least we won't have to suffer the "they're six months behind, so they're totally useless" anymore.
P.S: I'll make a prediction... We'll hear the "buuuuuuuuut it uses more tokens for the same task" for a few weeks, then we'll get Fable 5.1 and those same posters are going to post "Fable 5.1 is so much ahead you're missing out if you're still on that piece of turd that Fable 5 or K3 is".
My intuition says that the output quality difference is marginal compared to the change in price especially when taking into account the effects of prompt/context engineering and harness differences.
Essentially: since opus 4.6, working through a model's quirks with prompt/context engineering and harness development will yield significantly better output than just switching models to the latest.
I don't understand how DeepSeek can be so cheap with their cache pricing - ~0.003 usd / 1Mtok. 100x less than Kimi K3, or similar numbers against pretty much any other decently sized model to my knowledge. I've been using it whenever possible as even longer agent sessions cost few cents.
They just aren't in any hurry to forward those cost savings to you.
Look through the provider list for a company you are willing to do business with?
* Tons of gray testing going on for the last 2+ weeks (people at random getting the new v4 model for a while before its removed again).
* It also DeepSeek their 3th birthday this Friday.
* The its been almost 3 months from the v4 DeepSeek release, and the model everybody have been using, was not post-trained. That is what they have been doing during this time.

The Battlefront like game is impressive. Sure, the soldiers are backwards and the graphics are still kind of basic. But the entire movement system (run/walk/crouch/jump), gun mechanics, grenades, capture points, AI fighting / capturing back, etc ... Ended up playing it way too darn long lol The text is in mandarin but its not too hard to figure out the menu. Sniper is OP ;)
The Horizon 6 game has everywhere mesh colliders, shows when you off track dirt being kicked up, etc ... In general, both example are very well polished minus the reverse soldiers issue.
And the price is supposed to stay the same (beyond the doubling during Chinese workhours), because everybody got that update.
Assuming experts are uniformly distributed (I’m really not that familiar with the deep details there), that’s 2800/896*16 = 50 billion active parameters just for the active/expert part. Wild stuff, and I’m glad there’s at least some companies still publishing (and pushing, for open-weight models) total parameter count.
And: It sounds very believable that this would result in efficiency gains wrt. to compute necessary for “good”-quality inference. Does anyone know whether there currently even are any SOTA or near-SOTA models that are dense still?
Kind of like scaling your personal automobile to the weight of a semi, the semi is still going to be far more efficient in moving cargo, not that the semi will cost the same to operate as the original car.

- The blog post is explicitly saying that the model is open; that language was removed from the previously shared link
- It shows benchmarks
I've been playing around with it for the past few hours, and I think it's an amazing model. I'm not sure I could tell the difference between this and Fable in a blind test. The quota in the $100 Kimi Coding plan seems to roughly align with what I get from the $200 Anthropic plan when I primarily use Fable.
I's not just matching against titles. Ironically, I have an agent running daily scans, reading the contents of the top 200 stories of the day. It auto screens high-confidence ones and I make judgement calls on like 10-20 of them per day.
So, it's impossible to know whether your filter is working on this story yet, either.

But it does take some days after model release before they collect enough data.
Models that people like the design aesthetic of (Claude, GLM) tend to do better in LMArena than they do on other benchmarks. Design matters, but you look at a model like GPT-5.5 and it's behind Kimi K2.6, Sonnet 4.6, Qwen3.7 Max, and GLM-5.1 on LMArena's code leaderboard. Then you look at benchmarks like DeepSWE and GPT-5.5 blows them out of the water with only Fable and GPT-5.6 beating it.
I'm not saying that the LMArena leaderboard isn't useful, but I'm not sure how much weight I'd give it as a "code" leaderboard. I think often times it's a design comparison of simple front-end React apps rather than a coding comparison. GLM-5.2 is a very good model, but when you look at DeepSWE or Terminal-Bench v2, GPT-5.5 is well ahead.
Wonder if they’ll open-source this and show how many tokens it cost.
[0] https://www.kimi.com/blog/kimi-k3
Who needs superintelligence with you have 8,700 tokens/s at near Fable levels of performance???
This is like the Bill Gates, Paul Allen moment, but for hardware.
They can't even blame it on distillation this time, unless they want to claim that their own preferred security measures were ineffective in preventing Chinese access to Mythos.
I am very curious for the next batch of Chinese models. I have been using DeepSeek and it is nothing short of excellent.
I should maybe also mention that I have not used the later models like Opus or Fable, so my opinion might be a bit outdated.
When I remember that this site even showed Kimi having the highest score at one point https://eqbench.com
(Not posting link coz paywall)
Anthropic might dominate general purpose programming,but I think there's enough of a market for a model laser focused on game scripting or tool development for game studios.
I hope it succeeds in serving that audience.

Any recommendation for a cost effective subscription service?
Ok you can host this model once. What if I want a dozen subagents? Ok you can host it 12 times at once. What if we go a whole week only using max 4 at a time? Etc etc. The limits imposed by self-hosting might be bearable for a variety of reasons, but it's going to be more expensive and less convenient/useful.
> Kimi K3 is the first open model to reach 2.8 trillion parameters. It marks the latest step in Kimi's sustained push at the scaling frontier: for nine of the past twelve months, Kimi models have set the upper bound of open-model sizes.
https://www.kimi.com/blog/kimi-k3
Still sensible to mark proprietary for now though.
That said, as the frontier moves, "months old" becomes more and more useful. Opus-tier models are being used to write serious software, so we're going to start seeing open models pick up a lot more usage imo.
I'm expecting Anthropics reply soon though.
It would be trivial for them to distill Mythos.
https://platform.kimi.ai/docs/guide/kimi-k3-quickstart
I entered a question to try it, but as soon as I hit enter it wants my phone number for a login. No thanks.
Are you claiming a necessity ?
The question it came up with, "which U.S. state is closest to Africa?" is a pretty standard trivia question without any reason to believe other AIs would get confused. https://pellmell.ai/s/dccdeca69f929f79bc89317035610049
Even GPT-OSS-120b gets this right: https://pellmell.ai/s/1a43dfc7a3baa214aa0fa1b95d2c536a
IMHO an Ai is the llm plus it's harness.
A good harness would allow the llm to investigate on a map.
Just like the llm can use a python script to figure out how many r's there are in strawberry.
These tests are simply not that predictable of performance of the llm.
The other AIs don't see the question until they are asked to react.
From all the models available to me I'm most happy with Kimi K2.7 (given the cost/performance).
Is the release of this why Google's share price is down 4.5%?
Is them pricing at Sonnet level actually give us any information at all at how big Sonnet is or is there too much opacity around inference margins?
If that's true, then the price makes sense
Combine with the price it will surely more costly than gpt 5.6.
This was only a month and a half delay after Opus 4.8 and Fable 5 spent 18 days in embargo, resurrected with a strict classifier that handicaps it
We’re at endgame
The sentiment has shifted far too much amongst the investor community and amongst enterprises who are the life-blood of the revenue streams of Anthropic and OAI.
Further releases of Chinese models that demonstrate the gap is not growing substantially is a huge problem. The spending will be called into question.
How feasible is it to hook Kimi up to do GitHub code reviews? the Copilot quotas got really stingy recently
Is there proof of what you’re saying or is it just a guess?
https://code.claude.com/docs/en/zero-data-retention
Of course maybe there is some fine print I haven’t read, and obviously I get the point that it may not be trustworthy.
edit: whoops I just checked and the “business”/“teams” plans just agree not to use your data for training
Zero data retention is also "trust me dude".
There is no viable way of checking they are actually doing that.
That's assuming they don't put carve-out clauses in, like Anthropic did with Fable, which means data retention is back on the cards, no exceptions.
Also don't forget a zero data retention clause is still subject to the good old "law, or court or administrative order" contract clauses. :)
To get properly close to real zero-retention in a hosted model, you would have to use one of the verifiably private AI that runs in enclaves, e.g. Tinfoil (US) or Privatemode (Germany)[2]. Yes, still not the same as running on your own hardware, but a million lightyears ahead of "zero data retention" "trust me dude" clauses.
[1]https://tinfoil.sh/ [2]https://www.privatemode.ai/
I just wanted to know if that other person had proof or not, and I guess they didn’t. I would still rather have some semblance of an agreement than not have one at all — if you’re coding on a consumer plan you should just 100% assume anything you write with it will end up in the training set
A) use a provider that pinky-swears not to store your data. they obviously don't give a fuck about 'distillation attacks', so they have little motivation to voluntarily monitor and store your queries. reasonably high likelihood of privacy.
B) rent the hardware and run the model yourself. very high likelihood of privacy.
C) buy the hardware and run the model yourself. absolute certainty of privacy.
EDIT: Just switched my Kimi-CLI session to K3 and resumed my ongoing /goal... Will be interesting to see if I notice a difference.
That being said, it's awesome to have such an open-source model, even if now it's unusable mostly locally, with hardware improvements, in a couple of years, the verbosity/speed wouldn't matter as much as the intelligence.
> The full model weights of Kimi K3 will be released in the coming days. More details on the architecture, training, and evaluation will be published together with the Kimi K3 technical report.

It's incredibly funny, but I don't know whether it's related to distillation; it's probably quite rare for a distilled trace to mention which model it came from. (I'm not saying distillation doesn't happen, just that it's possibly unrelated.)
For your specific example, the internet is full of "As a large language model developed by OpenAI, I can't..." due to people pasting chatbot output without reading it. Seems reasonable for that to surface as part of the CoT for your question about model capabilities.
https://artificialanalysis.ai/models
It goes without saying, but if the open weights become as expensive as SOTA models, there's no point in using open weights. If nobody pays for open weights' development, the development dies out, and we're stuck with a US-controlled duopoly again. Which may be the biggest threat the world has seen from the US since nukes.
Personally, I like that there is an option to not send data to companies that have strong financial incentives to steal it.
Also, open weight foundation models can be distilled, so they’re providing a service that the US duopoly is actively blocking. Given that app specific distillation can get > 10x improvements on inference cost (with slight improvement of quality), it’s clear that it’ll win out over time.
