    I realize this post is about the pelican test, but in regards to coding, has anyone tried out the advisor strategy with V4?[0]

    e.g. Have V4 call out to Opus when it's uncertain, but otherwise handle execution.

    The results with Sonnet/Haiku in the blog post seemed promising, so I'm curious how it would go with these latest open models.

    The biggest differentiator for me: DeepSeek just does what I ask. I've tried using both GPT and Claude for reverse engineering recently, both refused. I even got a warning on my OpenAI account.

      We have an enterprise cursor account so I can try all the mainstream models. Using composer 2 on our own code which I obviously have the source code for I couldn't get it to turn on a debug flag to bypass license checks while I was troubleshooting something. Infuriating. It was like that old Patrick from SpongeBob meme.

      I don't understand why we would turn the models into law enforcement officers. Things that are illegal are still illegal and we have professionals to deal with crimes. I don't need Google to be the arbiter of truth and justice. It's already bad enough trying to get accountability from law enforcement and they work for us.

        They're probably worried about liability. Let's say that Oracle finds out you reverse engineered their DB using Gemini. You can be sure they will sue Google. Not just for providing the tools, but you could make the argument that it's actually Gemini doing the reverse engineering, and on Google's hardware no less.

          We need that lawsuit to happen already so we can establish precedent. The person in the driver's seat of the Tesla should be at fault. The engineer using the llm should be at fault. The person behind the gun not the manufacturer should be at fault.

          • Iolaum 17 minutes ago

            We shouldn't need a lawsuit. The legislative branch should pass a law clarifying those things, that's their job.

          Let's say that Oracle finds out you reverse engineered their DB using IDA Pro. Would you expect Oracle to sue Hex Rays?

          I don't understand why everything changes as soon as an LLM is involved. An LLM is just software.

          • sunnybeetroot 40 minutes ago

            The difference is IDA Pro doesn’t do something unless you instruct it to, an LLM is unpredictable and may end up performing an action you did not intend. I see it often, it presents me options and does wait for my response, just starts doing what it thinks I want.

            If they thought they would succeed, no doubt oracle would sue. I expect bad behavior from multinationals, especially oracle

            • lokar 40 minutes ago

              They would not even expect it to succeed, just make an example of the company (the lawsuit is the punishment) to discourage others.

        It's a simple corporate risk minimization strategy. Just look at how universally despised Grok is on HN. Not because it's a bad model, but because it has less aggressive alignment which means it can be coaxed into saying things that get Xai pilloried here and elsewhere.

        • noelsusman 5 minutes ago

          It's mostly just a bad model. Plenty of people would be willing to overlook the baggage if the model was even marginally better than the competition.

        • Wowfunhappy 27 minutes ago

          I just think Grok is a bad model. I haven't had success with it.

          I also think some of the image generation people are doing with Grok on Twitter is gross. But my issue isn't that Grok allowed those images to be generated, it's that (1) Elon seems to be promoting that sort of use and (2) people are publicly posting the results on Twitter and they're being left up.

        • ascorbic 15 minutes ago

          No, they've clearly put a lot of work into alignment. It's just that they've been trying to align it with Elon Musk rather than Amanda Askell. Unfortunately the more anti-woke they try to make it, the worse it seems to perform.

        • lostdog an hour ago

          Grok is despised because it has more aggressive alignment.

      This is kind of terrifying to me, regularly. No real manner of recourse to normal people without a following, potential exclusion from real fundamental tooling. Imagine OpenAI goes on to buy 20 companies and now you cant use Figma, Next, whatever just because you once tripped some very foggy line somehow. Not just OpenAI but the entire ecosystem is so... hard to read.

      I was asking Gemini about a quote from catch 22 and it kept dying mid stream saying it cant talk about it, god knows why, it had no violent or sexual content -- though that is in the book. I could imagine it dinging my whole workspace account just because ... shrug?...

      I know ideally the future is local, but I don't know how real that is for most people at least in the next few years with practical costs and power usage except I guess through a M* processor if you're in that ecosystem.

        Don't worry, you can just make your own Figma, Next, whatever if you have some thousand dollars worth of tokens. This is at least what all of the AI thought leaders have been telling me for the past couple of years.

      >> I even got a warning on my OpenAI account.

      I was using GPT 5.5 through Cursor recently, and it found what it thought to be a security-related issue. I read the code, didn't see what it was seeing, and said "Run the chain of operations against my local server and provide proof of the exploit."

      It thought for a few seconds, then I got a message in the chat window UI saying OpenAI flagged the request as unsafe, and suggested I use a "safer prompt."

      Definitely soured me on the model. Whatever guardrails they are putting are too hamfisted and stupid.

        Are you kidding?

        The main difference here is not that DeepSeek's model is completely free of censorship (although I'd wager it's less censored), but that it's open-weight. That has two major advantages:

        1) If Anthropic/OpenAI/Google bans you - you're screwed, you can't access their model at all, but if DeepSeek bans - you just go to another provider, or host the model yourself.

        2) If the model refuses to answer you can uncensor it (and this is getting easier and more automated day-by-day[1]).

    I've connected it with my vscode copilot and took it for a ride. I've tried both flash and pro. For a small POC flash was sufficient enough, quite fast, and dirt cheap. It did stop a few times (maybe latency issue?) but it did a good job. I used the pro to do some heavy lifting, planning, etc. and it did a fantastic job. I paid ~10 cents for a small proof of concept, that worked exactly how I prompted it.

    For me, this is a real alternative after I cancel my github copilot towards the end of the month..

  • wg0 14 hours ago

    Deepseek v4 Pro feels like Claude Opus 4.6 in it's personality but here's what I did find out about costs:

    I did cut loose Deepseek v4 on a decent sized Typescript codebase and asked it to only focus on a single endpoint and go in depth on it layer by layer (API, DTOs, service, database models) and form a complete picture of types involved and introduced and ensure no adhoc types are being introduced.

    It developed a very brief but very to the point summary of types being introduced and which of them were refunded etc.

    Then I asked it to simplify it all.

    It obviously went through lots of files in both prompts but total cost? Just $0.09 for the Pro version.

    On Claude Opus I think (from past experience before price hikes) these two prompts alone would have burned somewhere between $9 to $13 easily with not much benefit.

    Note - I didn't use Open router rather used the Deepseek API directly because Open router itself was being rate limited by Deep seek.

    • soerxpso an hour ago

      I've been having the same experience. Tasks like "go through this entire module and pedantically make it match my preferred styleguide exactly" were not worth a couple dollars with frontier models. It's nice to be able to put deepseek flash on stupid, unnecessary or highly speculative tasks without thinking about the cost.

    • TacticalCoder 6 minutes ago

      > would have burned somewhere between $9 to $13 easily with not much benefit

      With not much benefit compared to DeepSeek v4 Pro @ 9 cents (1/100th of the price) or did neither offer any benefit?

    • yogthos 2 hours ago

      I find a lot of the inefficiency also comes from the model just randomly poking around and grepping all the time which is the fault of the harness. I ended up building a Prolog based MCP where I use tree-sitter to parse the code into a graph, and then the model can just ask questions like 'what are all the functions connected to this function'. So, in case you're trying to focus on what a particular endpoint is doing, you can trivially and predictably trace the whole subgraphs of calls.

        I'm guessing downvoted because OpenRouter was mentioned in the note (which may not have been there originally), but aside from that this is a perfectly legitimate question. In order to reproduce we need to know how. Was it a coding agent like opencode, an IDE, or something else?

    • baldai 7 hours ago

      Only similarity it has to Opus 4.6 is the 4 in the name. I do not understand these dishonest comparisons. OOS models are vool, cheap and promising for a future -- but why are we pretending they are better than they are?

      • gmerc 6 hours ago

        Speak for yourself. I found switching from Opus 4.7 to be completely painless and in fact, due to the reliability of Anthropic’s API, less of a friction despite slower response times. Zero issues on a large mono repro

        • baldai an hour ago

          Hi, I am happy it works well for you. For me personally I struggle finding good use-cases in general for these OOS models. I am lightly technical but I do not manually code. So my flow is /grill-me (can take hours), make plan, review plan with 2. model, implement, review after implementation.

          Maybe it is because my tasks are usually chunkier, or because I cant code myself that I struggle using cheaper models. Feels like at every stage of this process SOTA model improves it by 5%, which adds up.

          But I am maybe ignorant of Opus level. My main driver is 5.5 and Opus is there for frontend and 2. opinion. In a past I also used Claude models for the chatting phase, but 5.5 took over recently. Maybe Deepseek is closer to Opus and I just overestimated the model compared to 5.5? I tried to give it benefit of being similar.

          Recently I started experimenting with Deepseek Flash, maybe hoping if plan is solid enough it can implement quickly and cheaply, but for now it feels not worth it.

          How do you use the model to see the benefits? Have you tried 5.5 and can you compare to that one as well?

          Thanks.

        • Reviving1514 5 hours ago

          What provider are you using? I have it a shot through open router and saw some weird half formed words coming through occasionally, would love to switch over and give it a proper go

  • curioussquirrel an hour ago

    V4 is definitely a step-up from V3.2 on our multilingual benchmarks.

    Two caveats: - when inferring through Openrouter, we've had a lot of issues with very slow speeds (TPS) and an occasional instability. I just checked and it's still 10-30 TPS on all available providers, which is not a lot for a model that likes to think as much as DeepSeek does.

    - the official DeepSeek API makes no guarantees of data privacy even for paying users.

    Both points could be moot with using it through Azure AI foundry (the latter is, afaik); I have yet to test that.

    In any case, happy to see more open-weights models that are somewhat competitive with SOTA models!

  • cheshire_cat 5 hours ago

    While the cost are lower than frontier models there are two factors that make DS4 Pro and K2.6 not as cheap as they might look.

    For DS4 Pro there's a discount going on for the official API, which sometimes gets overlooked and mixed up in discussions. Simon uses the full price in the comparison, so that's not an issue here.

    The other issue is that DS4 Pro and K2.6 often use way more reasoning tokens than the frontier models. In my testing there are certain pathological cases where a request can cost the same as with a frontier model because they use so much more tokens. To be fair I'm using DS and kimi via 3rd party providers, so they might have issues with their setups.

    But if you look at the Artificial Analysis pages of the models you'll see that DSv4 Pro uses 190M tokens and K2.6 170M tokens for their intelligence benchmark, while GPT 5.5 (high) only used 45M.[0][1][2]

    I recommend looking at the "Intelligence vs. Cost to Run Artificial Analysis Intelligence Index" ("Intelligence vs Cost" in the UI). The open source models are still cheaper to run, but not by as much as you'd think just looking at the token prices.

    • segmondy 3 hours ago

      This is very false DS4 is super cheap. I would advise to begin by reading their release paper. https://huggingface.co/deepseek-ai/DeepSeek-V4-Pro/blob/main...

      They introduce very novel methods to improve long context efficiency and attention. HCA & mCH. It requires only 27% of flops for inference and 10% for KV cache than v3.2. This makes it super efficient. Think of this. For flops, we can now serve more than 3x the amount with the same number of compute, and you would need 30% of prior KV cache.

      Furthermore, this release is a PREVIEW, DeepSeek is the real open labs and they not only cook up quite a bit with every single release, but they publish and share it. I'm running this locally.

      Let me tell you how "CHEAP" this is. With v3.2 I would run out of GPU ram, spill into system ram with 256k context. It ran quite alright and I was happy with my 7tk/sec. With this, I'm 100% in GPU ram with full 1million token, run more than 2x fast while getting better results.

      This is super cheap. moonshot has made it clear that they are starved for GPUs and that's why. If they had GPU capacity like we do in US and subsidized the models like we do here, they would be giving it away for free!

        Impressive! What is your setup? Are you running the full DeepSeek V4 Pro, or V4 Flash?

        • segmondy 2 hours ago

          I'm running flash. You can run it under 128gb, so a $3000 strix halo would do. My rig tho is 8 Nvidia gpus and spilling over to system ram.

    • cassianoleal 4 hours ago

      Sure that can happen but it hasn’t been my experience. I just spent a whole day using it for some pretty hefty refactors, many rounds of back-and-forths, thousands of lines of code changes, reviews, investigations, many subagents running parallel tasks, the works. Total cost $0.95, altogether.

      I had attempted this with Opus 4.6 in the past and it burned through the $10 budget I’d given it before it returned from my initial prompt.

      Even if it’s heavily discounted, it would still have cost me single digits for a complete solution vs double-digits for exactly nothing.

      • cheshire_cat 4 hours ago

        Sounds promising, thanks for your report.

        I didn't want to say that they're not cheaper to run, artificial analysis also shows that they're cheaper. My main point was about it being important to also look at token efficiency, not only cost per token, to get the full picture.

        • cassianoleal an hour ago

          I agree! I don't find Claude models to be particularly efficient anyway though. Maybe when running through Claude Code? I don't know, I tried it a while back but it didn't suit me and I kept hitting bugs so I dropped it in favour of something that does something closer to what I want rather than what the provider wants!

  • naaqq 4 hours ago

    DeepSeek’s official API has a cache hit rate of over 99% if you use it continuously within the same codebase for long sessions, so it’s much cheaper than frontier models. I have an example of 200M token session in claude code.

    • halfwhey 3 hours ago

      Might be a dumb question but do you have to read the files in the same order in new sessions to ensure the correct prefix for the cache?

      • WatchDog 2 hours ago

        Yes, you have to use the same session, I guess you could load up a bunch of context, then fork the session into a few different tasks, although I haven't tried it.

      • weiliddat 2 hours ago

        Also curious. With tool calls reading/searching different files, possible compacting reading a large codebase / long threads, I can't imagine how you hit 99% cache rate.

      • naaqq 2 hours ago

        Sorry, I was wrong here. I meant a single long session. And there’s no compression, the 1M context is only half used.

    • 542458 3 hours ago

      IMO there are two things that make me optimistic that we won’t see a big rug pull where price-to-capability ratio skyrockets relative to today:

      * As you’ve noted, people keep finding ways of slamming more intelligence into smaller models, meaning that a given hardware spec delivers more model capability over time.

      * Hardware will continue to improve and supply will catch up to demand, meaning that a dollar will deliver more hardware spec over time.

      I hope that one day we’ll look back on the current model of “accessing AI through provider APIs” the same way we now look back on “everyone connecting to the company mainframe.”

      • spacebanana7 3 hours ago

        I also hope that we’ll find effective ways to distribute load between small local models and heavyweight remote models. Sort of like what Apple tried to do in iOS.

        So much of what I ask codex to do doesn’t require full GPT 5 intelligence, and if 75% of the tokens were generated locally that’d save a massive amount of cost.

      • jerojero an hour ago

        Not a lot of people have this budget, and I'm not sure how many people with that type of cash are also interested in paying it for AI.

        Of course, this is fine for people in the bay area earning hundreds of thousands of dollars a year. But then your client base becomes so reduced its hard to justify the valuation these companies have.

        These AI companies are not hyped so much because they will offer a luxury product, they're valued because they're supposed to "change the world" which luxury does not do.

      • pimeys an hour ago

        We pay per token in our company. It is not hard to spend $100 for one morning coding session. So thousands per month per programmer. The company finds it valuable enough to pay for, but if I ever paid these from my own pocket I'd look into DeepSeek et.al.

      • Havoc 2 hours ago

        Comes down to what you mean by interactive usage. Most of chat & say openclaw usage is already within self-host range so no need to spend 200 a month on that.

        High end SOTA coding is harder, but even there I suspect a mix of usage based strong models and selfhost small is viable if necessary.

  • wolttam 38 minutes ago

    DS V4 Pro has rocked. ~250 million tokens through their API, which has cost me about $10, and some of that was at the non-discount rate. So ~$40 at the non-discount rate. I have yet to have a single request feel slow or get rejected.

    I've used K2.6, GLM5.1, and DSV4 all a good amount. They're all very impressive, but DSV4 has taken the cake.

  • deaux 9 hours ago

    I'm surprised that people here don't care at all about these models openly training on your data, especially if you use them straight from the model developer. Whereas things like "GitHub now automatically opts everyone into using their code for model training" get hundreds of justifiably angry comments, I never see this brought up anymore on posts like these talking about using Chinese models through OpenRouter. This might be explained by "well they're different people", but the difference is very stark for that to be the whole explanation.

      The cool thing about open-weights model is that you are free to use alternative providers that won't phone home to the original model creators.

      I see 6 alternative providers listed on Openrouter for DeepSeek V4 Pro for example.

      • eckelhesten 5 hours ago

        At least that’s what they’re telling you. It’s a ”trust me bro” scenario.

        I’d rather use the phone home version (deepseeks own endpoint). The benefit is that I’m fairly certain that they actually host the model I’m paying for.

          Some providers are based in the US or EU and would face legal repercussions for lying about what they do with your data. It's a bit more than "trust me bro". Off the top of my head, you can use Fireworks, for example, which is based in California and would face the same consequences for lying about their data policy as OpenAI or Anthropic would.

      At this point, that's kind of the reason I use open-weight models through the official providers when I can now.

      Otherwise, if they're going to keep releasing open-weight models, I'm going to keep giving them data.

          I made no such claims. Maybe you have something to share about why we need to have a negative view of free and open models based on publicly available frontier research.

    • edg5000 6 hours ago

      My policy is that I don't allow agents to access all code. Some of it is shielded behind bind mounts. Maybe this is a pathetic, artisanal (or ego-driven), reaction of mine to the inevitable. I allow them to work on about 90% of the code (most codebases fully), with some code being considered too valuable to expose to the vendor. When data is involved, LLMs only get to see anonymized data.

      This cute policy of mine won't affect anything though. The more we use the models, the more the models will replace this kind of work. Centralisation of power is inevitable; in Medival Europe, we used to have state & church ruling. In modern times but before the internet, it was probably state and banks. Maybe with ongoing digitization (bank offices disappearing) making banks less costly to operate; combined with with bank bailouts, maybe govenments will fully nationalize or at least banks will consolidate.

      Then the AI companies will consolidate with the internet information and communication companies (Google/Meta for the US, and Alibaba/Tencent for China). Maybe we'll end up with a few de-facto governmental megacorps that rule in tandem and close cooperation with the formal government, who might handle mostly infra, utilities and the army. The megacorp would control narrative more and take more of a paternal role (educating and protecting the citizens, normally handled by formal governments).

      Does this make sense?

If the latter, well, it seems like every day there's some news on some new model from somewhere, and it takes dedication to complain every time. There's also the factor that I believe DeepSeek is more open with the model, while others keep it entirely proprietary, which feels fairer and (personally) is also less offensive.

    I've been using v4 pro for the past few days and honestly in terms of quality it seems more or less on par with open AIs 5.4 or opus 4.6 (i havent tried 4.7)

    To be clear, i'm not doing state of the art stuff. I mostly used it for frontend development since i'm not great at that and just need a decent looking prototype.

    But for my purposes it's a perfectly good model, and the price is decent.

    I can't wait for open model small enough for me to run locally come out though. I hate having to rely on someone elses machines (and getting all my data exfiltrated that way)

    • FrasiertheLion 4 hours ago

      You can use Tinfoil for inference, which lets you use the model in the cloud while getting similar privacy as running locally: https://tinfoil.sh/inference.

      Disclaimer I'm the cofounder. This works by running the model inside a secure enclave (using NVIDIA confidential computing) and verifying the open source code running inside the enclave matches the runtime attestation. The docs walk you through the verification process: https://docs.tinfoil.sh/verification/verification-in-tinfoil

  • KronisLV 15 hours ago

    I'm currently paying for Anthropic's Max subscription (the 100 USD one) and I quite often hit or approach the 5 hour limits, but usually get to around 60-80% of the weekly limits before they reset (Opus 4.7 with high thinking for everything, unless CC decides to spawn sub-agents with Haiku or something).

    Those tokens are heavily subsidized, but DeepSeek's API pricing is looking really good. For example, with an agentic coding setup (roughly 85% input, 15% output and around 90% cache reads) I'd get around 150M tokens per month for the same 100 USD. Even at more output tokens and worse cache performance, it'd still most likely be upwards of 100M.

        You can't really distill a model without access to the internal weights. You could train on chat logs, but that's absolutely not the same thing, it doesn't even come close to comprehensively "extracting" the model's capabilities. And everyone does that in the industry anyway ever since ChatGPT was first released, some versions of Opus even claimed to be DeepSeek if you prompted them in Chinese.

        Glm5.1 is fantastic for me. But that could be how I use it, I don't ask it to build entire apps or entire features, instead asking it to build piecemeal functionality. For that it compares very well to chatgpt 5.4 (I haven't extensively tried 5.5, it might be better, might be same). I have given deepseekv4 pro a try but not much more than a try, as it performed subpar on 4 tasks in a row (missing the obvious/intended path, generating subpar slightly buggy code to make things work the not obvious way) , I gave up on it.

        Glm5.1 for me was a bit of a llama3.1 moment (first open model i could chat with that was usable in manging my inputs the intended way) for code, the first open model that was actually usable.

          Oh that's quite interesting and hasn't been my experience with regular backend code specifically with respect to tool calling. However that could be because the tool calling format in vllm for Deepseek v4 was broken until a few days ago and that's how I'm running it.

      Because V4 doesn't even beat Kimi K2.6 and GLM 5.1, which have been out longer. It's only talked about as much as it is because it's Deepseek and R1 was the first open source reasoning model. V4 isn't even multimodal (unlike Kimi) and the 1M context doesn't seem to perform particularly well.

    • zozbot234 5 hours ago

      DeepSeek V4 Pro has about 25GB worth of active parameters, so if you can fit the whole ~870GB weights + cache in RAM your tok/s is bounded above by 25GB divided into your system memory bandwidth in GB/s. If you can't fit your whole model in RAM you'll be bottlenecked to some degree by storage bandwidth which is in the single or low double digits in GB/s.

      Mind you, it's an absolutely sensible setup either way if you are just testing a few queries and are willing to run them unattended/overnight. Especially since the KV-cache size is apparently really low (~10GB is said to be typical) so you get a lot of batching potential even in consumer setups, which amortizes the cost of fetching weights.
