    Weights on HF here: https://huggingface.co/zai-org/GLM-5.3-Flash

    I decided to take the plunge and get myself four sparks at a decent price (and bought the QSFP cables from AliExpress because they are literally 1/2 the price of Amazon), even knowing Apple was going to release new hardware and there's probably a spark 2 on the horizon. It looks like this is going to be a decent fit for what I need. I've been experimenting with a two-node DS4 and it's _good_ at some tasks, but it really just spins its wheels when it hits the limit of what it can reason through.

    I can offload mundane/basic tasks to DS4 on two sparks, but I've been pushing it harder on some novel work and it just can't run on its own at all beyond a certain complexity level.

    I would love to see an Opus-4.8-level local model but TBH I just haven't got there yet. The models I've tried so far _are_ good but they aren't able to solve tough technical challenges, regardless of harness/prompting/etc.

    • disiplus 1 hour ago
      I will give it a try, but from the benchmarks it never exceeds the DS4 flash benchmarks by significant margin and And I feel that the throughput that you will get on those machines or what I'm getting with my local hosted flash will be so much worse that it's not worth it.

      > get myself four sparks at a decent price

      Wow, if you don't mind me asking. How and where?

      • mmastrac 1 hour ago
        I bought 4x Asus GX10 with the 1TB option. I don't understand why, but it's the only model in the whole lineup that isn't priced insanely.

        They were briefly on sale with a $200-off coupon, but they show up on warehouse deals from time-to-time as well.

          $4,000 isn't priced insanely? ye gads

          • swatcoder 1 hour ago
            Compare to the cost of professional-grade tools in other trades and craft hobbies.

            Sure, $4000 can be a lot of if you're a casual hobbyist or are struggle to meet everyday lifestyle costs, but it's definitely not "insane" if this is the trade you make your living from or if you've established a lifestyle that affords disposable income for your hobbies.

            And for some people, $4000 for a device you have complete control over and can repurpose and tinker with to your own needs and curiosities is a much much more justifiable expense than a $200/mo rental for some narrow-access tool that somebody else controls.

            • vehemenz 29 minutes ago
              That's only half the reason it's expensive.

              The other reason is that it would likely take years to spend $4000 (plus the real cost of electricity) worth of tokens on a 3rd-party provider that's running a similar limited, DS Flash type model. By that time, the hardware will be obsolete, assuming it's still operational.

              • swiftcoder 7 minutes ago
                > it would likely take years to spend $4000 (plus the real cost of electricity)

                Since that cluster only yields 20-30 tok/s on that size of model, at least a decade before the hardware breaks-even with current token costs, and that's not counting electricity. Assuming continued downward pressure on token prices, and the cost of electricity, it never pays for itself.

                • dannyw 2 minutes ago
                  As a counterpoint, my homelab/home-LLM hardware has appreciated in value by about 60% since I bought it.

                  Of course, it's not real unless I sell, and the value will eventually go down, but so far I have significant paper profits.

                  Also, DeepSeek token prices are continuing to _increase_, not decrease.

            • swiftcoder 56 minutes ago
              It's "insane" compared to the $1,500 it should have cost before the RAM crisis
            • chews 55 minutes ago
              I am pretty confident that given a $200 subscription on any of the big labs, you're getting $4000-$8000 per month in subsidized tokens... do what you wan't with your dough... and I too have a spark that I got really early (October 2025), but no, economically it does not compare to what's runnable locally in terms of quality from the frontier models. Economically, it looks like for as long as there are subscriber plans, you're better off renting.

              Before getting the spark, I was just using a google colab account, their $49 dollar plan allows you access to h100's and I can run qwen there in a Jupyter notebook... and if I really need that web front end I can just use cloudeflair/tailscale/the local ssh client to reverse tunnel it.

          • a3w 1 hour ago
            I thought 4000 in sum. No wait, 4000 per, plus tax. Or EUR pricing to similar accord. Ouch.
            • swiftcoder 1 hour ago
              Yeah, that little cluster costs about the same as a brand-new Dacia Sandero.

          ~$4000 USD each on Amazon, $175 for the cable.
          • mmastrac 57 minutes ago
            The cables are ~USD $50 from AliExpress although I'm not sure what the tariff situation is for Americans (I think I paid $75 all-in CAD for them)
        • cmrdporcupine 1 hour ago
          I mean, I have the same machine and the pricing is only what it is because it has that 1TB nVME in it instead of larger. nVME prices are insane and have been for months.

          Reality is on a single spark I'm constantly running out of room and it being an odd size M.2 slot it's a pain to upgrade. I'm setting up a NAS over RDMA via ConnectX though, that's fun.

          • mmastrac 58 minutes ago
            I already have a recycled QNAP-now-TrueNAS that has 10G connections into the fleet so the 1TB doesn't bother me at all. I did some rough math and I don't think I'll ever need to load weights off NFS for what I'm doing so far, but the capability is there.

      Agree. It doesn’t even have to be local, using models in this size class through OpenRouter will reveal their limits if you work side by side with Opus level models regularly.

      There are a lot of social media posts about people cancelling their Anthropic or ChatGPT subscriptions after installing a local LLM. I’ve used local LLMs a lot and I spend a lot of time with frontier models and the difference is still huge. As far as I can tell, the social media posts about local LLMs replacing frontier models are either wishful thinking, engagement bait, or people who must be working on much simpler projects with a much higher tolerance for slop than I have.

      • weitendorf 46 minutes ago
        I have exactly the same opinion

        Over the last couple years I’ve had to learn sales and understand the thought process behind this better, and I think I’m beginning to understand it

        The psychology is that most people aren’t really trying to optimize for productivity (even most people who think they are) on an ROI basis, because their compensation is too decoupled from their actual raw output, and more closely coupled to how differentiated their marginal contribution is to peers. They’re much more incentivized to spend their personal/work time optimizing for being more skilled or acquiring some kind of competitive advantage relative to baseline.

        Most people don’t consciously run the numbers of “I get paid $X/hr to add $Y of value” or model pay at work as something with variable inputs (eg something that can be increased with high performance), so it makes sense to them to spend 20 hours of time to save $100 or to make themselves 5% less efficient to take home 0.5% more or avoid doing something they don’t want to start doing.

        NOT saying this always happens or that they’re stupid for doing so. I didn’t even realize how much I had been doing it myself until I started recognizing it, and shifted to having my own comp/performance fully aligned with the company’s P/L.

        It actually makes a lot of sense IF you can accurately estimate incremental upside (which is much harder and more diffuse than modeling downside if you’re salaried a employee) or if the upfront skill/knowledge investment that looks like bikeshedding pays off in the long run.

      • disiplus 1 hour ago
        To be fair, there is no 3 turns that I don't have to jump in into what Opus 5 is doing. There is either some regression or my prompting skills are so much worse now. Flash is not perfect and honestly some things depend on how big context do you keep. So I'm keeping like a really short context with my flash, but it works okay, even though it has a tendency to overthink, and yeah, I run it always in max effort mode.
    • 0xbadcafebee 1 hour ago
      If you used the bare API pricing, 1M tokens @ 30% input/70% output/50% cached, you'd pay $0.05805. Even with four discounted sparks, how much are you paying for the same tokens/distribution?
      • swatcoder 1 hour ago
        There's soooo much by way of experiments, explorations, tinkering, and even projects that you can't possibly pursue through a some SaaS API.

        The more reasonable comparison is against rented GPU's, while looking at tradeoffs in latency and upload/download/storage/instance management overhead.

        Buying hardware for local models is meeting a wholly different need than buying tokens through OpenRouter or whatever.

        • vehemenz 25 minutes ago
          It cuts both ways. A GPU in your basement is a depreciating asset with fixed computing power and consumes electricity. Switching model providers is trivial.
        • mmastrac 1 hour ago
          For me it's entirely because I have a bunch of projects with my own personal data that would be tough to do with openrouter/claude or any other cloud.

          For example, I have a small posix-shell-based LLM harness that can SSH into my NAS and run organization tasks using the local DS4Flash that I have right now. It's already been a massive help for me to keep me organized, and that's just 2x DGX Spark's worth of compute.

  • mrngld 1 hour ago
    Chinese labs are so used to manipulating benchmarks to try to flatter inferior models that when they finally have one that's really pretty good I think the official announcement here undersells it.

    https://deepswe.datacurve.ai/

    That's pretty solid. Smarter and cheaper than Luna xhigh, not as smart but less expensive than Luna max. Smashes deepseek v4 flash, and even worse it matches v4 pro at a tiny fraction the cost. Roughly equivalent to sol medium, at a fraction the cost.

    They should've just lead with real, up to date data, because it's good, not the silly old tactics like comparing to Opus 4.8 when 5.0 is out in many of their charts.

    Congrats to them!

    • cameronh90 37 minutes ago
      Maybe others have found otherwise, but I find the benchmarks drastically different to real world "feel" of a model, even within the same harness. I'm not sure if this just reflects personal interaction styles, or if it is indicative of benchmaxxing or unrealistic automated benchmarking methodology.

      Opus 5 consistently comes at or near the top, but outputs constant unreadable jibberish. Meanwhile GPT 5.6 Luna medium tends to be rated pretty poor on agentic tasks compared to the Chinese lab open models, but I find the latter much more likely to lose track of their own behaviour during a long-horizon task or get stuck in a doom loop.

      (This isn't a comment on GLM-5.3 Flash as I've not used it!)

      • trey-jones 31 minutes ago
        I've been using 5.3 since they initially announced it and my gut feel is that it's not as good as 5.2 for agentic tasks. I'm still using it - I don't think it's bad. I'm just not convinced it's better.
    • redox99 1 hour ago
      It's also better than Sol (at whatever effort) at designing pretty UIs. I have a Codex sub and I've been using this model for UI stuff.

      It's what people know. Opus is just the common target.

      > Smarter and cheaper than Luna xhigh, not as smart but less expensive than Luna max. Smashes deepseek v4 flash

      The problem with this and DeepSWE is it goes for a very specific profile. I'm not convinced DeepSWE is any accurate in actual work. It's surely a different signal (compared to some that allow cheating) but it has its own issues, e.g. weak harness.

      Luna is great at following instructions but bad instructions or anything not covered = death.

      Deepseek is more analytical. Good for bug tracking.

      GLM is a better all rounder in some ways. Better at creativity.

  • matheusmoreira 55 minutes ago
    You guys read Z.ai's terms of service, right?

    Broad and perpetual license over inputs and outputs, and even your name and profile picture.

    Vague prohibitions on whatever may harm Z.ai’s "interests" or even the "national interests" of any country.

    Vague prohibitions on "disturbing" or "inappropriate" content, whatever that is.

    Vague prohibitions on discussing Z.ai, even my posting this comment violates it.

    Can ban you if you, in the "sole and absolute opinion" of Z.ai, have violated these broad terms, and if you paid for the discounted yearly plan kiss your money goodbye.

    • g3f32r 52 minutes ago
      Isn't this practically every TOS though?

      Nearly every TOS I've ever read has a "We can ban you for any reason, or no reason, are under no obligation to disclose any reason." line somewhere in it.

      HN's for example

      > We reserve the right, at our sole discretion, to change or modify portions of these Terms of Use at any time.

      > You acknowledge that Y Combinator may establish general practices and limits concerning use of the Site,

      > You further acknowledge that Y Combinator reserves the right to change these general practices and limits at any time, in its sole discretion, with or without notice.

      > Y Combinator reserves the right to investigate and take appropriate legal action against anyone who, in Y Combinator’s sole discretion, violates this provision, including without limitation, removing the offending content from the Site, suspending or terminating the account of such violators and reporting you to the law enforcement authorities.

          This is not uncommon.

          Also, it only applies to their chat offering, not the api. OpenRouter also offers the API with ZDR.

          While shitty, i’d say that its really not that special.

          • moralestapia 9 minutes ago
            ???

            None of the major LLM chat providers (ChatGPT, Claude and Gemini, and I just confirmed this) claim rights over your input.

            They also don't claim rights over your output, but because of how copyright law might apply, they explicitly assign all the rights to the generated output.

            Not just that but, even if they wanted to claim ownership of the output, courts in the US have deemed that copyright cannot be assigned to machine-generated output.

            So yeah, happy to take a look at a counter-example if you have one (aside from GLM 5.3, obv.).

    • zaj00l 45 minutes ago
      I get all that.

      Then alternatives are:

      - Grok - where I absolutely have 0 trust in X.ai's interst in "pushing humanity forward".

      - OpenAI and Anthropic - which seem to try to be building the biggest moat they can by pushing to ban open models. And at the same time want to be an Arbiter of what level of intelligence I can use.

      - Google and Meta - I don't need to talk about the practices of these companies.

      Yes, the terms of service aren't great. But the alternatives aren't great either. I don't believe that a future which OpenAI and Anthropic are pushing for has my best interest in mind.

        All the American companies you mentioned still follow American law and regulation. Skirting that blatantly has big consequences.

        Chinese companies do not follow American laws and there are absolutely no consequences for violating it.

        Moreover, the average American is not even aware of exactly what the legal/judicial environment is like in China. If your code and data is stolen, you can't fly to China and demand justice in the courts.

    Is the actual Z.AI ecosystem good enough to replace the main drivers like Codex and Claude? Because it looks like Z Code is just a Codex fork. Just like the Kimi Code one is.

    What irks me about this is that the harnesses seem to be just an afterthought here.

    Don't get me wrong, I love messing around with installing Pi, getting it hooked up with OpenRouter, and just trying all kinds of different stuff, local models, etc... but when it comes to literally just setting up a productivity environment and trusting my entire machine with it, I just run Codex.

    I have heard from anecdotes where people have indeed replaced their main drivers with DeepSek V4 Flash or GLM and state that "it's almost as good as... [claude/gpt]" but I never hear anyone say "yeah, this is the model/harness that I now run on my machine and don't mess with it"

      I don't see a situation where subscription payers move outside American LLMs (chatgpt, claude, gemini)

      And I don't see a situation where serious API payers are OK with handing the Chinese state all their data. Like manufactures of decades past did and learned a hard, even existential, lesson for it. The state mantra has been "Collect and Copy" for a long time now, tech just hasn't had that moment to experience it yet.

      So that leaves local hosting/leasing, but one of those has totally non-practical economics and the other doesn't have enough compute to meet any kind of real demand.

      I also have yet to meet a single person who isn't neck-deep in the tech space mention a Chinese LLM. It's 100% the big American three.

      If anything it's custom chips from the labs that threatens Nvidia.

        • WarmWash 47 minutes ago
          Google probably serves more tokens then OAI and Anthropic combined, even if many of those tokens aren't from explicit gemini requests, but from AI overviews and other service integrations.

          xAI is already selling spare compute, and basically exists just to gas spacex's perceived valuation.

    • Bluestein 1 hour ago
      This is the takeaway here: That's how they have been serving it at scale as Ox-Alpha. This is a definitional moment.-

      Further quote:

      "Compared with our initial baseline on the same hardware, we achieved a 3× improvement in end-to-end serving performance, reaching hardware efficiency and per-token cost comparable to mainstream NVIDIA GPUs. This demonstrates that Chinese chips can support frontier-model inference efficiently and economically at scale."

      Another self-inflicted own courtesy of US government policy.

      While I think China would always get to hardware self-sufficiency eventually, all export controls have done is (1) accelerate China's development, and (2) divert revenue that would've otherwise gone to NVIDIA/AMD/etc instead.

      • mrngld 1 hour ago
        Long term it's irrelevant. The only relevant thing is that there's lots of money in chips that can do high performance inference. You see all kinds of competitor products in development or already on the market even here in the US where there are no such restrictions. Cerebras comes to mind. It's natural and expected that eventually Nvidia will either have to keep way ahead or competition will catch up with specialized products.

        That doesn't mean by any stretch of the imagination Nvidia will disappear. But the entire stock market valuation, not just tech, has had me scratching my head for a while.

      • ignoramous 1 hour ago

        • mlinsey 1 hour ago
          Revoked or not, just ever having those controls signals to the Chinese ecosystem that you're not necessarily a reliable supplier (Would you trust US export policy to remain stable for the next ~decade given the state of US politic?) and to the Chinese government just how strategically important you see these components.

          This isn't the kind of thing you can hash out in public and go back and forth on. Once you put it out there, the other party will take steps to make sure they don't have to rely on us in the long run.

        • bigbadfeline 53 minutes ago
          The export controls were not revoked, only reduced, and not before, but after China refused to buy low performing chips. Top gear was and is still sanctioned, as is any EUVL equipment.
          • bigbadfeline 20 minutes ago
            And to add to the above: by building their own supply chain for chips, China is helping the unprivileged, those who can't front-run the market with long-term contracts. If China wasn't producing their own chips, the prices for us would be even higher.

            Similar to the war-pricing of oil, China's reduction of imports is actually helping to keep our inflation from going even higher.

      This is no surprise [0] [1].

      >> "They are already there on open weight models and Jensen knows that it is only a matter of time until China catches up with GPUs or other AI accelerators."

      It is also why Nvidia becoming a bank for other AI companies who are unable to find VCs to fund them isn't really a good thing and that is bearish.

    With tiny models surpassing huge, 6 months old models on benchmarks, does anybody have some smart words to share on how these still "feel" different?

    Artificial Analysis ranks GPT 5.6 Luna similar to GPT 5.4, but that never matches my real world experience. AA seems to do a good job making a single number as representative as possible but there is still so much benchmarks don't communicate.

    > it outperforms GLM-5.2 across benchmarks and real-world workloads at one-tenth the price, while approaching Claude Opus 4.8 on coding and agentic benchmarks.

    From a biased source, but would be big if true. I've had great results with GLM 5.2.

    From their subscription page, the smallest plan gives you about 97M tokens weekly for 5.3 but 292M for 5.3 Flash. Not exactly 10x the limit.

      The recent and slightly smaller DSv4 Flash is also GLM 5.2 equivalent (or close enough)

      It's at least close (even if not better) from the Ox Alpha runs. For the price it's definitely great.

    At the current 50%-off GLM-5.3-Flash price ($0.075/M input, $0.25/M output; cached input $0.015/M), surprisingly, roughly $400–900/month would buy token throughput comparable to fully exhausting Claude Max 20×

    > 320B total parameters and just 18B active parameters

    This is pretty hefty for a "flash" model, even a 256 GB setup is insufficient at q4 - and q4 is already the worst-but-still-acceptable quant in my experience. The benchmarks look great, especially since GLM tends to be more honest than the average Chinese lab, but you’ll need to splurge to run it at home.

    @edit: so many releases that I forgot to math. This fits just fine in q4, realistically the minimal hardware would be 192gb - so blazing fast on double rtx 6000 pro and usable on 256gb unified memory. You could even go with 5bit quant on 256gb.

    … you’ll still need to splurge, though.

    When reading this type of announcements, always have keen eyes on graphs.

    e.g. "Agent Coding Performance by Effort Level" cuts Y-axis from 0~20.

    - This makes it as if GLM-5.3-Flash made a bigger jump than it claimed as the Y-axis does not increase much (stupid trick used in biz reports)

    I did mention that ox was working ok for me, and having an open-weight comparable to close to SOTA makes it very compelling for me to try it out locally (well, only if I got more VRAM)

      they also conspicuously omitted GPT 5.6 Luna from comparison. It scores lower, but is also cheaper. MiMo 2.5 is not a valid comp at this point

      edit: nevermind. it is there in the artifical analysis scatter plot, but is greyed-out.

      MUCH more interesting is that in that chart, their cost is WAY off. The actual chart shows GLM 5.3 Flash at $0.09, but their chart shows $0.045...

    • dakolli 43 minutes ago
      They're obviously in a pickle, nobody is going to continue to pay $15-50 a mm tokens here soon. There's a reason OpenAI stopped training large models last week, and it's not because of "saftey" or "alignment" they know these gigantic models are not worth the squeeze.
  • cootsnuck 1 hour ago
    If we fast forward say 5 years, I don't see how we don't end up in world where people (and enterprises) are more savvy with how they use LLMs. Meaning, more models, smaller models, weirder models, more specialized models, etc. And all of it running on a variety of hardware (edge devices, personal computers, on-demand cloud compute).

    I don't see how NVIDIA can keep their spot as belle of the ball. If LLMs and friends are truly to become as useful and ubiquitous as everyone thinks they will, then commoditization is the only option.

    • drob518 59 minutes ago
      We need to figure out what the real pricing is for a going concern. Right now, everyone is subsidizing and discounting to grow (or maintain) market share. The big question is whether the steady state, market derived inference pricing is above or below what we’re seeing today. I honestly don’t know. Anthropic had said that inference is profitable, but they’re clearly not yet profitable overall with training and buildouts still happening.

    I'm starting to think that this whole sanctioning China may motivate and prompt them to do more and better in every field.

    It's too big, bright and resourceful of a country to choose confrontation instead of collaboration.

        There isn't one global "international law" for copyright. There are treaties that countries negotiate with each other.

        If the USA wanted a copyright treaty with China bad enough, we would negotiate one. China is not breaking any laws here, international or otherwise.

      • epolanski 43 minutes ago
        No major power respects nor cares about international law.

        Intellectual property is part of WTO agreements but enforcement is domestic.

        US companies do it too, regularly, they simply hire and poach staff from competitors.

        Proving it to be IP theft is difficult unless you can prove documents being passed. But often all you need is the know-how of the hired talent.

        All I can say is that even if it is, I was almost glad to go back to using DS4 Flash. Because 0XAlpha was just so friggin slow to complete a task because of the level of circular reasoning that it would go over and over into, sometimes even returning no output. If I just wanted something done I would switch from a free model to a paid one which is crazy.
        • denysvitali 1 hour ago

    > To overcome the relatively limited compute and memory capacity of individual chips, we built a dedicated inference engine for this architecture on top of SGLang. Notably, this effort was accelerated by our GLM-5.3-powered infrastructure agent, which assisted engineers in developing and optimizing kernels, diagnosing performance bottlenecks, and improving the serving stack — creating a feedback loop in which the model helped optimize the system serving the model itself.

    > (...) Compared with our initial baseline on the same hardware, we achieved a 3× improvement in end-to-end serving performance, reaching hardware efficiency and per-token cost comparable to mainstream NVIDIA GPUs. This demonstrates that Chinese chips can support frontier-model inference efficiently and economically at scale.

    It might be one of the most actually practical tasks that AI might've done because the compounding effects of it and also its implications are/feels so immense. It feels as if Nvidia might be in a slight turbulence from it.
