    Open Source as it gets in this space, top notch developer documentation, and prices insanely low, while delivering frontier model capabilities. So basically, this is from hackers to hackers. Loving it!

    Also, note that there's zero CUDA dependency. It runs entirely on Huawei chips. In other words, Chinese ecosystem has delivered a complete AI stack. Like it or not, that's a big news. But what's there not to like when monopolies break down?

    • chvid an hour ago

      The incredible arrogance and hybris of the American initiated tech war - it is just a beautiful thing to see it slowly fall apart.

      The US-China contest aside - it is in the application layer llms will show their value. There the field, with llm commoditization and no clear monopolies, is wide open.

      There was a point in time where it looked like llms would the domain of a single well guarded monopoly - that would have been a very dark world. Luckily we are not there now and there is plenty of grounds for optimism.

        Still not sure how I feel about China of all places to control the only alternative AI stack, but I guess it's better than leaving everything to the US alone. If China ever feels emboldened enough to go for Taiwan and the US descends into complete chaos, the rest of the world running on AI will be at the mercy of authoritarian regimes. At the very least you can be sure noone is in this for the good of the people anymore. This is about who will dominate the world of tomorrow. And China has officially thrown their hat in the ring.

          I always find it an illuminating experience about the power of mass propaganda every time I see an American believe they somewhat have the moral high ground over China, despite starting a new war somewhere around the globe either for petrol or on behalf of Israel every six months.

          • willsmith72 17 minutes ago

            Not American, but it undoubtedly does have moral high ground.

            Chinas setup is amazing for moving from undeveloped to developed, with 30 years of momentum and everyone pulling in one direction.

            That doesn't mean it's positive in human rights

              > That doesn't mean it's positive in human rights

              Isn't the US building mass detention camps right now for all the brown people there? And arresting / detaining / demanding papers from any and everyone? With federal agents killing civilians?

              Don't get me wrong, China is also horrible here, they have their own camps.

              But pretending the US is positive wrt human rights is a wild take in 2026.

              Of course not. When it comes to SOTA LLMs you have the choice between two bad options. For many, choosing the Chinese option is just choosing the lesser of two evils (and it's much cheaper).

              For now indeed, the people that want to get rid of it are currently in power.

              The US was one of the first democracies in the world, and many countries followed suit. But the US hasn't kept up, and now the powers that be have exploited the weaknesses in the system. With arguably the biggest one being giving the president too much power (appointing supreme court justices, executive orders, etc).

              Democracy in most of the countries is just theater. Trump promised no more wars iirc.

        • Cthulhu_ 40 minutes ago

          Moral stances aside, I'd argue it's healthy that the US gets competition from abroad. I appreciate the boost that the world is getting from China - infrastructure and construction projects are a huge benefit to economies. Their focus on green energy has caused a huge influx of affordable solar panels, home batteries, EVs, etcetera, helping reduce the dependency on fossil fuels - while the US and especially the other big money spenders in the middle east would rather the world remain fully dependent on them. But for the past years Europe and now Asia are feeling the pain from being overly reliant on that.

          China's policies and government aren't morally defensible and I do fear that they will become more aggressive in spreading their influence and policies onto other countries, but from an economic standpoint what they're doing is super effective. While the previous world power (the US) is stuck in infighting and going through cycles of fixing/undoing the previous administration's damages, instead of planning ahead.

            AFAIK: Current Mistral models are not competitive with SOTA-models that come out of the USA or China. They are "good enough" for enterprise usage when you don't need SOTA performance.

            Their main selling point is: They are neither US-American nor Chinese. That's a real moat in today's world. I think at the moment they feel quite comfortable.

        • koe123 an hour ago

          I grew up in the states when I was younger, always feeling some closeness to Americans even after I moved back to Europe.

          With all that goes on it has changed. Recently I sat on a plane near some Americans discussing their holidays here, and I noticed I felt contempt. Sitting their with insane privilege as their government torches the world.

          Individuals remain individuals, and one really ought not to be prejudice. However the lack of resistance I see in in the “land of the free” as their “democratic” institutions collapse just makes me believe they never cared at all. In France cars are torched if the pension age is raised. In America the rise facism apparently doesnt matter to them.

          • TomGarden 12 minutes ago

            I a European who spent the last decade in America and I'm not sure I'd call Americans privileged compared to Europe. With money being the one means you have to be treated well in society, comparing it to Europe, America feels like the hunger games. Want healthcare (ie surviving)? Healthy food? To own your house? Welcome to the games

          • mettamage 42 minutes ago

            From my small bubble it's not that. I'm Dutch, married to an American who now knows enough Dutch such that we can treat it as a secret language when we're in the US.

            My family in law seems to swing slightly republican. As a Dutchie, I could get some answers because I'm too naive not to talk about politics. So I got to probe a bit. What I simply found was that they'd say "I can't trust the news, none of it. Not CNN, not Fox News, nothing". Then I'd say "well in the Netherlands, I'd argue that while news outlets have their bias, you can trust them on basic factual reporting". She looked at me with a stare that I could only describe as "oh but honey, you're too young and naive to understand". To which I thought "you don't know the Netherlands. We're not perfect but we're nowhere near as deranged as what I'm seeing here".

            I think that explains a lot of it for some people. The trust in the media, all media, is completely broken. Trump has how many fellonies now? Can't trust it. Kamala is doing what now? All talk. DOGE is fixing the government? I fucking hope so! But can't trust the damn news. Whether they do or don't, they are always burning money, god damn bureaucrats.

            I feel that's the mindset that my family in law has.

            • fastasucan 15 minutes ago

              My running hypothesis has been the trust breakdown arises from social-media overexposure driving lazy nihilism, which in turn gave free reign to a uniquely-corrupt class of politicians. But I'm not sure how to neutrally evaluate that.

          • sterlind 29 minutes ago

            not all of us are just "sitting here with insane privilege." it's quite dangerous for some of us right now.

            I'm trans. this Administration does not like us. after Charlie Kirk's murder, things got legitimately scary. Musk was retweeting people who called us "deranged bioweapons" who needed to be "forcibly institutionalized." NSPM-7 is surveilling and infiltrating trans organizations. the Heritage Foundation proposed labeling us as "ideological extremists," in the same category as neo-Nazis. if I'm arrested, I'll go to a men's prison where I'll likely be given to a violent inmate as his cellmate to "pacify" him (V-coding.)

            so yeah, I keep my head down. a lot of Jews kept their heads down in Germany in the '30s, you know? and just like then, it doesn't seem like other countries are too keen on taking us in as refugees. I hope that changes if things get bleak.

            It’s not that it doesn’t matter to Americans. It is worse; half the population (or at least, half the voting population), is thrilled with the development of fascism. The other half has been ringing the alarm bells for well over a decade; it seems to make no difference.

            And you’re right, most Americans do not understand the privileges they have or give one single shit about democracy; it is just not a salient political issue. But eggs… don’t get me started on eggs.

            • Cthulhu_ 34 minutes ago

              It's probably a bit more nuanced than "half this, half that"; when you look at the facts, most voters aren't that extremist. A lot of votes vote one way or the other because they would simply never vote for the other.

              This is why the swing voters / swing states are so important in the US, because only a few million are flexible enough to switch sides.

              Of course the core issue is that there's a two party system; while I'm sure that in a healthy democracy the current republican and democrat parties would be the bigger ones, they wouldn't have a majority.

            This is not something to be proud of. You guys are giving yourself loaned freebies, retiring 5+ (!) years earlier than countries like BeNeLux and Germany, and are pretty much expecting the EU to eventually pick up the pieces which will drag us all down.

            • the_gipsy 18 minutes ago

              That's bullshit. Pensions are not a zero-sum game, and other countries don't have to pay for them.

              It just doesn't make sense to delay retirement while youth unemployment is such a big problem. We ALL should be fighting like France, in many aspects.

              • jorvi 14 minutes ago

                Other countries don't directly pay for the pensions, but France is staring into a giant fiscal abyss because of their low retirement age (and other generous social benefits). Any attempt to change those results in the country being taken hostage by rioters, thus nothing changes.

                At some point France will be in too deep shit in look to the EU to cover for them. We will all pay for that. And it is deeply unfair because other countries their citizens have accepted later retirement and more frugal benefits to keep their country fiscally healthy.

                France could cover the fiscal hole in other ways, but taxing corporations and wealth higher also consistently ends up being blocked. And each year the hole gets deeper.

        • miroljub 30 minutes ago

          The reason you see the distancing from America in European media is the Republican government. Democrats were not better to Europe than Republicans, but you have to understand that current European leaders are vassals to the US Democrats and the Epstein-List".

          In the near future, one of two things will happen:

          - Democrats will regain power, and the EU will be happy with the USA again.

          - EU regime will swear an oath to the Republicans and continue to be vassals to them and the Epstein-List.

          Whatever happens, one thing is sure: Epstein-List will stay in control.

                  Is your contention that Hong Kong is also a totalitarian society? Have you been to Hong Kong in the last 5 years? I feel like people saying these sorts of things are just completely divorced from reality.

                  > Covid saw people caged and sealed in their houses.

                  No. There were a few incidents very early on, when everyone was (quite understandably) panicking about a new, deadly virus that nobody had ever seen before, when some local city officials barred the doors of people who had just come from Wuhan. That was a scandal inside China, and it was immediately reversed.

                  What China did do quite extensively was border quarantine, and during localized outbreaks (caused by cases that slipped through quarantine at the border), mass testing and quarantine measures. This was during a once-in-a-generation pandemic that killed millions of people. In China, these measures saved several million lives. The estimates are that China's overall death rate was about 25% that of the US, and these measures are the reason. By the way, Taiwan and Australia took nearly identical measures, and I very much doubt that you would call them totalitarian societies.

        China’s governments actions are on a completely different level - for example:

        “””

        Since 2014, the government of the People's Republic of China has committed a series of ongoing human rights abuses against Uyghurs and other Turkic Muslim minorities in Xinjiang which has often been characterized as persecution or as genocide.

        “”” https://en.wikipedia.org/wiki/Persecution_of_Uyghurs_in_Chin...

        • Cthulhu_ 31 minutes ago

          Not so much a trade war as basic economic forces, and it's been going on for much longer than that. When infrastructure improves, companies and customers can look further to get their stuff done. If it's cheaper to do your industrial or manufacturing work abroad and have it transported to your country, that just happens.

          The powers that be try to slow this down by banning imports outright (you can't for example import American chicken into Europe because of food safety laws), or high import taxes (Chinese EVs have a 50% import tax in Europe and the US to protect the local car manufacturers. Which is fair because the Chinese EV manufacturers are state-sponsored so their prices are unfair. Then again, western companies get billions in investor money to push the prices down).

          You mean the west handed their industry to china over the last 15 years? Its not like the US is any better off in this. The EU is not a country, so you can't talk about it as if it was. Each country has their own companies and industries. There is AI in Europe, and its growing, however we might not be as "energetic" about destroying our countries to build giant data centers to serve our billionaire overlords. That does not mean that there is no investment, there is, including a bunch of American corporations like Amazon. But there is also a lot of corruption and bribing (lobbying - lets call it what it really is, no more whitewashing) going on around that too.

          So again, stop referring to EU as a country, we are not, and it just annoys any Europeans as it comes of as "Americans who don't understand the world outside of the USA".

            Ask Gemini today if the United States is trying to destroy the nation of Iran, and it will feed you the (white-washed) party line, straight from the White House, with a bit of 'some people disagree' thrown in. No mention of America's threats of "Complete annihilation", "Killing a civlization", and all the rest.

            > Summary: The U.S. is currently engaged in an active war aimed at dismantling the Iranian government and its military capabilities, but it distinguishes this from destroying the country or its people. However, the humanitarian impact—including civilian casualties from airstrikes and the domestic crackdown by Iranian security forces—has led many international observers to warn that the campaign risks long-term instability and "state collapse" rather than a simple transition of power.

            It does do quite a bit better if you ask it about the genocide in Gaza, summarizing the case for it, and citing only token justifications from the guilty party.

        Theoretically yes. It is entirely possible to poison the training data for a supply chain attack against vibe coders. The trick would be to make it extremely specific for a high value target so it is not picked up by a wide range of people. You could also target a specific open source project that is used by another widely used product.

        However there is so many factors involved beyond your control that it would not be a viable option compared to other possible security attacks.

  • hodgehog11 an hour ago

    There are quite a few comments here about benchmark and coding performance. I would like to offer some opinions regarding its capacity for mathematics problems in an active research setting.

    I have a collection of novel probability and statistics problems at the masters and PhD level with varying degrees of feasibility. My test suite involves running these problems through first (often with about 2-6 papers for context) and then requesting a rigorous proof as followup. Since the problems are pretty tough, there is no quantitative measure of performance here, I'm just judging based on how useful the output is toward outlining a solution that would hopefully become publishable.

    Just prior to this model, Gemini led the pack, with GPT-5 as a close second. No other model came anywhere near these two (no, not even Claude). Gemini would sometimes have incredible insight for some of the harder problems (insightful guesses on relevant procedures are often most useful in research), but both of them tend to struggle with outlining a concrete proof in a single followup prompt. This DeepSeek V4 Pro with max thinking does remarkably well here. I'm not seeing the same level of insights in the first response as Gemini (closer to GPT-5), but it often gets much better in the followup, and the proofs can be _very_ impressive; nearly complete in several cases.

    Given that both Gemini and DeepSeek also seem to lead on token performance, I'm guessing that might play a role in their capacity for these types of problems. It's probably more a matter of just how far they can get in a sensible computational budget.

    Despite what the benchmarks seem to show, this feels like a huge step up for open-weight models. Bravo to the DeepSeek team!

      • hodgehog11 an hour ago

        I don't want to give away too much due to anonymity reasons, but the problems are generally in the following areas (in order from hardest to easiest):

        - One problem on using quantum mechanics and C*-algebra techniques for non-Markovian stochastic processes. The interchange between the physics and probability languages often trips the models up, so pretty much everything tends to fail here.

        - Three problems in random matrix theory and free probability; these require strong combinatorial skills and a good understanding of novel definitions, requiring multiple papers for context.

        - One problem in saddle-point approximation; I've just recently put together a manuscript for this one with a masters student, so it isn't trivial either, but does not require as much insight.

        - One problem pertaining to bounds on integral probability metrics for time-series modelling.

          First you clone the API of the winner, because you want to siphon users from its install-base and offer de-risked switch over cost.

          Now that you’re winning, others start cloning your API to siphon your users.

          Now that you’re losing, you start cloning the current winner, who is probably a clone of your clone.

          Highly competitive markets tend to normalize, because lock-in is a cost you can’t charge and remain competitive. The customer holds power here, not the supplier.

          Thats also why everyone is trying to build into the less competitive spaces, where they could potentially moat. Tooling, certs, specialized training data, etc

          Yeah, it’s an interesting one. I think inertia and expectations at this point? I don’t think the big labs anticipated how low the model switching costs would be and how quickly their leads would be eroded (by each other and the upstarts)

          They are developing their moats with the platform tooling around it right now though. Look at Anthropic with Routines and OpenAI with Agents. Drop that capability in to a business with loose controls and suddenly you have a very sticky product with high switching costs. Meanwhile if you stick with purely the ‘chat’ use cases, even Cowork and scheduled tasks, you maintain portability.

      API prices may be profitable. Subscriptions may still be subsidized for power users. Free tiers almost certainly are.

      I was thinking the same. How can it be than other providers can offer third-party open source models with roughly the similar quality like this, Kimi K2.6 or GLM 5.1 for 10 times less the price? How can it be that GPT 5.5 is suddenly twice the price as GPT 5.4 while being faster? I don't believe that it's a bigger, more expensive model to run, it's just they're starting to raise up the prices because they can and their product is good (which is honest as long as they're transparent with it). Honestly the movement about subscription costing the company 20 times more than we're paying is just a PR movement to justify the price hike.

      • peepee1982 2 hours ago

      I haven't seen anyone claiming that API prices are subsidized.

      At some point (from the very beginning till ~2025Q4) Claude Code's usage limit was so generous that you can get roughly $10~20 (API-price-equivalent) worth of usage out of a $20/mo Pro plan each day (2 * 5h window) - and for good reason, because LLM agentic coding is extremely token-heavy, people simply wouldn't return to Claude Code for the second time if provided usage wasn't generous or every prompt costs you $1. And then Codex started trying to poach Claude Code users by offering even greater limits and constantly resetting everyone's limit in recent months. The API price would have to be 30x operating cost to make this not a subsidy. That would be an extraordinary claim.

      Have you considered... not subscribing? You can ask the top models via chats for specific stuff, and then set up some free CLI like mistral.

      If you're trying to make a buck while unemployed, sure get a subscription. Otherwise learn how to work again without AI, just focus on the interesting stuff.

    • azuanrb 11 minutes ago

      I have $20 ChatGPT subscription. Stopped Anthropic $20 subscription since the limit ran out too fast. That's my frontier model(s).

      For OSS model, I have z.ai yearly subscription during the promo. But it's a lot more expensive now. The model is good imo, and just need to find the right providers. There are a lot of alternatives now. Like I saw some good reviews regarding ollama cloud.

        I didn't express this well but my interest isn't "who is in the top spot", and is more _why and _how various labs get the results they do. This is also magnified by the fact that I'm not only interested in hosted providers of inference but local models as well. What's your take on the best model to run for coding on 24GB of VRAM locally after the last few weeks of releases? Which harness do you prefer? What quants do you think are best? To use your sports metaphor it's more than following the national leagues but also following college and even high school leagues as well. And the real interest isn't even who's doing well but WHY, at each level.

        It is funny seeing people ping pong between Anthropic and ChatGPT, with similar rhetoric in both directions.

        At this point I would just pick the one who's "ethics" and user experience you prefer. The difference in performance between these releases has had no impact on the meaningful work one can do with them, unless perhaps they are on the fringes in some domain.

        Personally I am trying out the open models cloud hosted, since I am not interested in being rug pulled by the big two providers. They have come a long way, and for all the work I actually trust to an LLM they seem to be sufficient.

        For coding Opus 4.5 in q3 2025 was still the best model I've used.

        Since then it's just been a cycle of the old model being progressively lobotomised and a "new" one coming out that if you're lucky might be as good as the OG Opus 4.5 for a couple of weeks.

Happened with solar panels, steel, evs, sea food - it's a well tested strategy and it works really well despite the many flavors it comes in.

        That being said a job well done for the wrong reasons is still a job well done so we should very much welcome these contributions, and maybe it's good to upset western big tech a bit so it's remains competitive.

      Open weight!

      • alecco 3 hours ago

        Please don't slander the most open AI company in the world. Even more open than some non-profit labs from universities. DeepSeek is famous for publishing everything. They might take a bit to publish source code but it's almost always there. And their papers are extremely pro-social to help the broader open AI community. This is why they struggle getting funded because investors hate openness. And in China they struggle against the political and hiring power of the big tech companies.

        Just this week they published a serious foundational library for LLMs https://github.com/deepseek-ai/TileKernels

        Others worth mentioning:

        https://github.com/deepseek-ai/DeepGEMM a competitive foundational library

        https://github.com/deepseek-ai/Engram

        https://github.com/deepseek-ai/DeepSeek-V3

        https://github.com/deepseek-ai/DeepSeek-R1

        https://github.com/deepseek-ai/DeepSeek-OCR-2

        They have 33 repos and counting: https://github.com/orgs/deepseek-ai/repositories?type=all

        And DeepSeek often has very cool new approaches to AI copied by the rest. Many others copied their tech. And some of those have 10x or 100x the GPU training budget and that's their moat to stay competitive.

        The models from Chinese Big Tech and some of the small ones are open weights only. (and allegedly benchmaxxed) (see https://xcancel.com/N8Programs/status/2044408755790508113). Not the same.

      I don't think we need to compare models to Opus anymore. Opus users don't care about other models, as they're convinced Opus will be better forever. And non-Opus users don't want the expense, lock-in or limits.

      As a non-Opus user, I'll continue to use the cheapest fastest models that get my job done, which (for me anyway) is still MiniMax M2.5. I occasionally try a newer, more expensive model, and I get the same results. I have a feeling we might all be getting swindled by the whole AI industry with benchmarks that just make it look like everything's improving.

      • versteegen 3 hours ago

        Which model's best depends on how you use it. There's a huge difference in behaviour between Claude and GPT and other models which makes some poor substitutes for others in certain use cases. I think the GPT models are a bad substitute for Claude ones for tasks such as pair-programming (where you want to see the CoT and have immediate responses) and writing code that you actually want to read and edit yourself, as opposed to just letting GPT run in the background to produce working code that you won't inspect. Yes, GPT 5.4 is cheap and brilliant but very black-box and often very slow IME. GPT-5.4 still seems to behave the same as 5.1, which includes problems like: doesn't show useful thoughts, can think for half an hour, says "Preparing the patch now" then thinks for another 20 min, gives no impression of what it's doing, reads microscopic parts of source files and misses context, will do anything to pass the tests including patching libraries...

      • ind-igo 3 hours ago

        Agree with your assessment, I think after models reached around Opus 4.5 level, its been almost indistinguishable for most tasks. Intelligence has been commoditized, what's important now is the workflows, prompting, and context management. And that is unique to each model.

        • vidarh 2 hours ago

          Same for me. There are tasks when I want the smartest model. But for a whole lot of tasks I now default to Sonnet, or go with cheaper models like GLM, Kimi, Qwen. DeepSeek hasn't been in the mix for a while because their previous model had started lagging, but will definitely test this one again.

          The tricky part is that the "number of tokens to good result" does absolutely vary, and you need a decent harness to make it work without too much manual intervention, so figuring out which model is most cost-effective for which tasks is becoming increasingly hard, but several are cost-effective enough.

          In theory, sure, but as other have pointed out you need to spend half a million on GPUs just to get enough VRAM to fit a single instance of the model. And you’d better make sure your use case makes full 24/7 use of all that rapidly-depreciating hardware you just spent all your money on, otherwise your actual cost per token will be much higher than you think.

          In practice you will get better value from just buying tokens from a third party whose business is hosting open weight models as efficiently as possible and who make full use of their hardware. Even with the small margin they charge on top you will still come out ahead.

          • oceanplexian 2 hours ago

            There are a lot of companies who would gladly drop half a million on a GPU to have private inference that Anthropic or OpenAI can’t use to steal their data.

            And that GPU wouldn’t run one instance, the models are highly parallelizable. It would likely support 10-15 users at once, if a company oversubscribed 10:1 that GPU supports ~100 seats. Amortized over a couple years the costs are competitive.

              > There are a lot of companies who would gladly drop half a million on a GPU to have private inference that Anthropic or OpenAI can’t use to steal their data.

              Obviously, and certainly companies do run their own models because they place some value on data sovereignty for regulatory or compliance or other reasons. (Although the framing that Anthropic or OpenAI might "steal their data" is a bit alarmist - plenty of companies, including some with _highly_ sensitive data, have contracts with Anthropic or OpenAI that say they can't train future models on the data they send them and are perfectly happy to send data to Claude. You may think they're stupid to do that, but that's just your opinion.)

              > the models are highly parallelizable. It would likely support 10-15 users at once.

              Yes, I know that; I understand LLM internals pretty well. One instance of the model in the sense of one set of weights loaded across X number of GPUs; of course you can then run batch inference on those weights, up to the limits of GPU bandwidth and compute.

              But are those 100 users you have on your own GPUs usings the GPUs evenly across the 24 hours of the day, or are they only using them during 9-5 in some timezone? If so, you're leaving your expensive hardware idle for 2/3 of the day and the third party providers hosting open weight models will still beat you on costs, even without getting into other factors like they bought their GPUs cheaper than you did. Do the math if you don't believe me.

            To me, the important thing isn't that I can run it, it's that I can pay someone else to run it. I'm finding Opus 4.7 seems to be weirdly broken compared to 4.6, it just doesn't understand my code, breaks it whenever I ask it to do anything.

            Now, at the moment, i can still use 4.6 but eventually Anthropic are going to remove it, and when it's gone it will be gone forever. I'm planning on trying Deepseek v4, because even if it's not quite as good, I know that it will be available forever, I'll always be able to find someone to run it.

                One GB200 NVL72 from Nvidia would do it. $2-3 million, or so. If you're a corporation, say Walmart or PayPal, that's not out of the question.

                If you want to go budget corporate, 7 x H200 is just barely going to run it, but all in, $300k ought to do it.

            I was curious, and some [intrepid soul](https://wavespeed.ai/blog/posts/deepseek-v4-gpu-vram-require...) did an analysis. Assuming you do everything perfectly and take full advantage of the model's MoE sparsity, it would take:

            - To run at full precision: "16–24 H100s", giving us ~$400-600k upfront, or $8-12/h from [us-east-1](https://intuitionlabs.ai/articles/h100-rental-prices-cloud-c...).

            - To run with "heavy quantization" (16 bits -> 8): "8xH100", giving us $200K upfront and $4/h.

            - To run truly "locally"--i.e. in a house instead of a data center--you'd need four 4090s, one of the most powerful consumer GPUs available. Even that would clock in around $15k for the cards alone and ~$0.22/h for the electricity (in the US).

            Truly an insane industry. This is a good reminder of why datacenter capex from since 2023 has eclipsed the Manhattan Project, the Apollo program, and the US interstate system combined...

        It is more than good enough and has effectively caught up with Opus 4.6 and GPT 5.4 according to the benchmarks.

        It's about 2 months behind GPT 5.5 and Opus 4.7.

        As long as it is cheap to run for the hosting providers and it is frontier level, it is a very competitive model and impressive against the others. I give it 2 years maximum for consumer hardware to run models that are 500B - 800B quantized on their machines.

        It should be obvious now why Anthropic really doesn't want you to run local models on your machine.

      • bokkies 3 hours ago

        Apparently glm5.1 and qwen coder latest is as good as opus 4.6 on benchmarks. So I tried both seriously for a week (glm Pro using CC) and qwen using qwen companion. Thought I could save $80 a month. Unfortunately after 2 days I had switched back to Max. The speed (slower on both although qwen is much faster) and errors (stupid layout mistakes, inserting 2 footers then refusing to remove one, not seeing obvious problems in screenshots & major f-ups of functionality), not being able to view URLs properly, etc. I'll give deepseek a go but I suspect it will be similar. The model is only half the story. Also been testing gpt5.4 with codex and it is very almost as good as CC... better on long running tasks running in background. Not keen on ChatGPT codex 'personality' so will stick to CC for the most part.

      There we go again :) It seems we have a release each day claiming that. What's weird is that even deepseek doesn't claim it's better than opus w/ thinking. No idea why you'd say that but anyway.

      Dsv3 was a good model. Not benchmaxxed at all, it was pretty stable where it was. Did well on tasks that were ood for benchmarks, even if it was behind SotA.

      This seems to be similar. Behind SotA, but not by much, and at a much lower price. The big one is being served (by ds themselves now, more providers will come and we'll see the median price) at 1.74$ in / 3.48$ out / 0.14$ cache. Really cheap for what it offers.

      The small one is at 0.14$ in / 0.28$ out / 0.028$ cache, which is pretty much "too cheap to matter". This will be what people can run realistically "at home", and should be a contender for things like haiku/gemini-flash, if it can deliver at those levels.

      For the curious, I did some napkin math on their posted benchmarks and it racks up 20.1 percentage point difference across the 20 metrics where both were scored, for an average improvement of about 2% (non-pp). I really can't decide if that's mind blowing or boring?

      Claude4.6 was almost 10pp better at at answering questions from long contexts ("corpuses" in CorpusQA and "multiround conversations" in MRCR), while DSv4 was a staggering 14pp better at one math challenge (IMOAnswerBench) and 12pp better at basic Q&A (SimpleQA-Verified).

    This is shockingly cheap for a near frontier model. This is insane.

    I am uncomfortable about sending user data which may contain PII to their servers in China so I won't be using this as appealing as it sounds. I need this to come to a US-hosted environment at an equivalent price.

    • torginus 2 hours ago

      This is just a random thought, but have you tried doing an 'agentic' pelican?

      As in have the model consider its generated SVG, and gradually refine it, using its knowledge of the relative positions and proportions of the shapes generated, and have it spin for a while, and hopefully the end result will be better than just oneshotting it.

      Or maybe going even one step further - most modern models have tool use and image recognition capabilities - what if you have it generate an SVG (or parts/layers of it, as per the model's discretion) and feed it back to itself via image recognition, and then improve on the result.

      I think it'd be interesting to see, as for a lot of models, their oneshot capability in coding is not necessarily corellated with their in-harness ability, the latter which really matters.

      • simonw 2 hours ago

        I tried that for the GPT-5 launch - a self-improving loop that renders the SVG, looks at it and tries again - and the results were surprisingly disappointing.

      Let me tell you how much the Pro one sucks... It looks like failed Pedersen[1]. The rear wheel intersects with the bottom bracket, so it wouldn't even roll. Or rather, this bike couldn't exist.

      The flash one looks surprisingly correct with some wild fork offset and the slackest of seat tubes. It's got some lowrider[2] aspirations with the small wheels, but with longer, Rivendellish[3], chainstays. The seat post has different angle than the seat tube, so good luck lowering that.

          Some other reactions:

          I wonder which model will try some more common spoke lacing patterns. Right now there seems to be a preference for radial lacing, which is not super common (but simple to draw). The Flash and Pro one uses 16 spoke rims, which actually exist[1] but are not super common.

          The Pro model fails badly at the spokes. Heck, the spokes sit on the outside of the drive side of the rim and tire. Have a nice ride riding on the spokes (instead of the tire) welded to the side of your rim.

          Both bikes have the drive side on the left, which is very very uncommon. That can't exist in the training data.

          I've been using all Kimi K2.6, gpt-5.4 and now Deepseek v4 (thought not extensively yet) in Claude Code and I can say it works much better than you'd expect. It looks like the system prompt and tools are pulling a lot of weight. Maybe the current models are good enough that you don't need them to be trained for a specific harness.

    How can you reasonably try to get near frontier (even at all tps) on hardware you own? Maybe under 5k in cost?

    • revolvingthrow 3 hours ago

      For flash? 4 bit quant, 2x 96GB gpu (fast and expensive) or 1x 96GB gpu + 128GB ram (still expensive but probably usable, if you’re patient).

      A mac with 256 GB memory would run it but be very slow, and so would be a 256GB ram + cheapo GPU desktop, unless you leave it running overnight.

      The big model? Forget it, not this decade. You can theoretically load from SSD but waiting for the reply will be a religious experience.

      Realistically the biggest models you can run on local-as-in-worth-buying-as-a-person hardware are between 120B and 200B, depending on how far you’re willing to go on quantization. Even this is fairly expensive, and that’s before RAM went to the moon.

      • zargon 3 hours ago

        Flash is less than 160 GB. No need to quantize to fit in 2x 96 GB. Not sure how much context fits in 30 GB, but it should be a good amount.

        • redrove 3 hours ago

          It seems to be 160GB at mixed FP4+FP8 precision, FYI. Full FP8 is 250GB+. (B)F16 at around double I would assume.

          • zargon 3 hours ago

            There is no BF16. There is no FP8 for the instruct model. The instruct model at full precision is 160 GB (mixed FP4 and FP8). The base model at full precision is 284 GB (FP8). Almost everyone is going to use instruct. But I do love to see base models released.

    • zozbot234 3 hours ago

      Run on an old HEDT platform with a lot of parallel attached storage (probably PCIe 4) and fetch weights from SSD. You'd ultimately be limited by the latency of these per-layer fetches, since MoE weights are small. You could reduce the latencies further by buying cheap Optane memory on the second-hand market.

    • 542458 4 hours ago

      The low end could be something like an eBay-sourced server with a truckload of DDR3 ram doing all-cpu inference - secondhand server models with a terabyte of ram can be had for about 1.5K. The TPS will be absolute garbage and it will sound like a jet engine, but it will nominally run.

      The flash version here is 284B A13B, so it might perform OK with a fairly small amount of VRAM for the active params and all regular ram for the other params, but I’d have to see benchmarks. If it turns out that works alright, an eBay server plus a 3090 might be the bang-for-buck champ for about $2.5K (assuming you’re starting from zero).

    The paper is here: [0]

    Was expecting that the release would be this month [1], since everyone forgot about it and not reading the papers they were releasing and 7 days later here we have it.

    One of the key points of this model to look at is the optimization that DeepSeek made with the residual design of the neural network architecture of the LLM, which is manifold-constrained hyper-connections (mHC) which is from this paper [2], which makes this possible to efficiently train it, especially with its hybrid attention mechanism designed for this.

    There was not that much discussion around it some months ago here [3] about it but again this is a recommended read of the paper.

    I wouldn't trust the benchmarks directly, but would wait for others to try it for themselves to see if it matches the performance of frontier models.

    Either way, this is why Anthropic wants to ban open weight models and I cannot wait for the quantized versions to release momentarily.

    like generating output, but not actually running the bash command so not creating the PR ultimately. I wonder if it's a model thing, or an opencode thing.

    • inventor7777 4 hours ago

      Weren't there some frameworks recently released to allow Macs to stream weights from fast SSDs and thus fit way more parameters than what would normally fit in RAM?

      I have never tried one yet but I am considering trying that for a medium sized model.

      • simonw 4 hours ago

        I've been calling that the "streaming experts" trick, the key idea is to take advantage of Mixture of Expert models where only a subset of the weights are used for each round of calculations, then load those weights from SSD into RAM for each round.

        As I understand it if DeepSeek v4 Pro is a 1.6T, 49B active that means you'd need just 49B in memory, so ~100GB at 16 bit or ~50GB at 8bit quantized.

        v4 Flash is 284B, 13B active so might even fit in <32GB.

        • zozbot234 3 hours ago

          The "active" count is not very meaningful except as a broad measure of sparsity, since the experts in MoE models are chosen per layer. Once you're streaming experts from disk, there's nothing that inherently requires having 49B parameters in memory at once. Of course, the less caching memory does, the higher the performance overhead of fetching from disk.

        • zargon 3 hours ago

          > ~100GB at 16 bit or ~50GB at 8bit quantized.

          V4 is natively mixed FP4 and FP8, so significantly less than that. 50 GB max unquantized.

        • inventor7777 4 hours ago

          Ahh, that actually makes more sense now. (As you can tell, I just skimmed through the READMEs and starred "for later".)

          My Mac can fit almost 70B (Q3_K_M) in memory at once, so I really need to try this out soon at maybe Q5-ish.

        • EnPissant 3 hours ago

          Streaming weights from RAM to GPU for prefill makes sense due to batching and pcie5 x16 is fast enough to make it worthwhile.

          Streaming weights from RAM to GPU for decode makes no sense at all because batching requires multiple parallel streams.

          Streaming weights from SSD _never_ makes sense because the delta between SSD and RAM is too large. There is no situation where you would not be able to fit a model in RAM and also have useful speeds from SSD.

      • zozbot234 3 hours ago

        These are more like experiments than a polished release as of yet. And the reduction in throughput is high compared to having the weights in RAM at all times, since you're bottlenecked by the SSD which even at its fastest is much slower than RAM.

    • sbysb 4 hours ago

      It's difficult because even if the underlying model is very good, not having a pre-built harness like Claude Code makes it very un-sticky for most devs. Even at equal quality, the friction (or at least perceived friction) is higher than the mainstream models.

      • raincole 4 hours ago

        OpenCode? Pi?

        If one finds it difficult to set up OpenCode to use whatever providers they want, I won't call them 'dev'.

        The only real friction (if the model is actually as good as SOTA) is to convince your employer to pay for it. But again if it really provides the same value at a fraction of the cost, it'll eventually cease to be an issue.
