  The timing looks like they are trying to take the wind out of Qwen's sails by releasing this on the same day that Qwen released the weights of Qwen3.8-max. Or maybe it's coincidence...

  For comparison I looked at Qwen's claimed benchmarks for Qwen3.8-max (https://qwen.ai/blog?id=qwen3.8). Assuming each published set of benchmarks is believable, it looks like v4 Pro 0813 is better on average but overall performance is comparable. Pro 0813 is much cheaper. If you don't need vision capabilities then you don't have much reason to use Qwen3.8-max.

  - 43.6 on HLE (Presumably without tools). Pro 0813 is a little worse.

  - 86.6 on Terminal Bench 2.1. Pro 0813 is better.

  - 55.9 on NL2Repo. Pro 0813 is better.

  - 27 on Agent's Last Exam. Pro 0813 is a little worse.

  - 72.5 on Toolathon-Verified. Pro 0813 is better.

  - 56.6 on DeepSWE 1.1. If the DeepSWE listed for Pro 0813 is the same version, then Pro is better.

  - 27.3 on AutomationBench. If the AutomationBench (Public) listed for Pro 0813 is the same, then Pro is better.

  I guess we do need to wait to see if the upcoming DS pricing increase is enough to change the value proposition. As it is now, they could double or triple prices and it still would be a better value to use DS. I bet they know that.

  • trollbridge

    today at 5:23 PM

    By that standard, the release of Grok 4.6 was also timed on the same day.

    Given how I think DeepSeek operates... I think they just release it when they feel it's ready, and don't even seem that concerned with what other people are doing.

    • somenameforme

      today at 5:28 PM

      Their leaks would confirm this sort of attitude. They're not trying to become the top player or anything like that - just working to play their part in pushing LLM tech forward and going from there. It was quite refreshing from the 'here's how we're going to dominate the world' nonsense. It's undoubtedly the same attitude that just lets them shrug and cancel the fund raising round after the leaks came from said funding round.

      • trollbridge

        today at 5:36 PM

        The founder of DS's stated goal is to get to AGI. He thinks this is the path to get there.

        Kind of interesting, when compared to the hubris from American frontier labs.

        Benefits of having a well performing hedge fund funding DeepSeek.

        IIRC, Demis attempted to start a fund inside DeepMind but it was killed off. In an alternative world where he manages to pull that off, perhaps DeepMind would still be independent with Demis at the helm.

      • surgical_fire

        today at 5:33 PM

        Their stance on LLM development is why they earned my respect in a time when OpenAI and Anthropic only earn my mistrust.

        That, and the fact that DS is an insanely capable model.

    • parsimo2010

      Actually, yes. I just didn't know about Grok's release because they aren't on the front page of HN.

    Official pricing only kinda matters for an open weight model, no?

    • parsimo2010

      today at 5:31 PM

      It still matters as a point of comparison until other providers come online. If the consensus price from other providers is much different that can be compared then. But for now we have $0.435 / $0.87 for v4 Pro 0813 (with increase announced but we don't know the new pricing), and $2 / $6 for Qwen3.8-max. So until we get other data points that is what we have to look at.

      • eli

        I wondered if the promised change in pricing is actually going to be deepseek bringing up their cached costs. They're extremely inexpensive.

    Fable's guardrails would never let it do something like Cybergym so at least for that one it's measuring Opus 5

    • wren6991

      today at 5:26 PM

      We have a first-party figure from the system card [1]:

      > Mythos 5 reproduced 83.8% of targeted vulnerabilities on a single try, and produced at least one crash in 99.4% of tasks. This is comparable to Claude Mythos Preview, which reproduced 83.1% of targeted vulnerabilities and produced a crash in 97.1% of tasks. By contrast, Claude Opus 4.8 achieved a score of 78.1% (95.7% any crash).

      So their quoted figure exactly matches the figure for Mythos Preview, although they don't state the provenance. It could also quite possibly be an independent measurement of Opus 5.

I've been using the last Deepseek Flash update for a week and I'm amazed. It was a capable model for easy tasks but now it looks like it can do some heavy development for peanuts.

I can't wait to try this new one.

https://api-docs.deepseek.com/quick_start/pricing/

Competitive with opus 4.8 but weaker than sol or fable. About 20x cheaper.

• xynelius

  today at 5:20 PM

  If that wasn't impressive enough, it's actually ~60x cheaper if you take into account the typical cache-read/input/output split in agentic coding, and the deep discount for cache reads offered by DeepSeek. Opencode has some public data on the typical split [1]:

  For DeepSeek V4 Pro the typical split is 750 in, 290 out, 82k cached.

  Cost per request for V4 Pro: $0.000875 per request.

  Equivalent Opus cost (w/o taking into account cache write costs): $0.052 per request.

  [1] https://opencode.ai/docs/go/#usage-limits

• JacobAsmuth

  today at 5:06 PM

  Per token. You need to look at pricing per task.

  • trollbridge

    today at 5:25 PM

    ... which still comes out cheaper, since DeepSeek caches so much more.

    I keep track of my token consumption even on subscription plans and my equiv. cost for my 5.6-Sol usage is around $4000-$8000 a month.

• swiftcoder

  today at 4:36 PM

  How does it stack against the updated Deepseek Flash version?

  • pixelesque

    today at 4:57 PM

    I've found Pro to be a lot better per "task" than the recently released Flash for code reviews and things (via OpenRouter running in pi.dev).

    Flash makes a lot more initial mistakes, and then has to re-check stuff, and produces much more output compared to Pro. It often gets to the correct result eventually, but the output volume is often 5x more than for Pro, and the initial outputs are often wrong, with the first few saying something wrong (like there's a bug, or the code won't compile when it does), and then saying things like "Wait, let me re-check:", or "Actually, looking at it more carefully:" and then it thinks a bit more and eventually gets to the right answer.

    • surgical_fire

      I use a plan -> implement wotkflow for this reason.

      pro plans, flash implements. I am super happy with how flash behaves like that.

    • swiftcoder

      yeah, I've definitely noticed one has to be quite precise to keep Flash on the straight-and-narrow

  • k__

    today at 4:42 PM

    Around 5 percentage points better. (E.g., 87% instead of 82%)

    • Gecko4072

      today at 4:46 PM

      So not worth it over flash? Even at ~7x the size it isn't worth the price hike. Flash may be a monster of a model due to all the RL it received from free usage everywhere.

      • networked

        today at 5:00 PM

        I haven't tried DeepSeek V4 Pro 0813 yet. Recent experience tells me that larger models are worth it in non-obvious ways. MiMo-V2.5-Pro solved problems that DeepSeek V4 Flash 0731 couldn't solve for me: for example, adding a live counter for elided reasoning lines to a terminal-based coding harness. You wouldn't be able to tell from the scores on their respective Artifical Analysis page (https://artificialanalysis.ai/models/mimo-v2-5-pro, https://artificialanalysis.ai/models/deepseek-v4-flash). I like the DeepSeek V4 models, though. They critiqued my engineering decisions better than MiMo, and they seem to have a distinct aesthetic in the SVGs they write.

        • trollbridge

          today at 5:27 PM

          Interesting - I've been dropping into MiMo-V2.5-Pro-UltraSpeed whenever Flash seems to be "stuck" and it usually figures it out. I use UltraSpeed just because I'm so frustrated by then that I'm impatient.

          I still find 5.6-Sol can solve some things neither of those can, but it's so slow (and it's so hard to trace / debug the reasoning) that I just let it run overnight.

          • networked

            today at 5:43 PM

            What about 5.6 Terra and especially Luna? Luna scores pretty high on benchmarks and seems to have different habits (like a denser pattern of tool use) and blind spots.

            I'm trying out a development workflow where I generate mundane code with MiMo and Luna (and soon V4 Pro 0813?) and have Opus 5 (running on only a Pro subscription) review and refactor it. I'm not sure it will justify the context switching, but it's an interesting exercise.

      • saaga

        Yea that's what I was thinking. Flash is nuts. I find I have to be a more precise and specific with it but damn. It's crossed a threshold of production grade coding for sure.

            Well sure but you're running on tens of thousands of dollars of hardware.

It appears that the only available endpoint (as of this writing) requires enabling "Allow paid endpoints that train on request data" in the OpenRouter privacy settings. I hope additional paid providers will become available that don't require training on data.

• jubilanti

  today at 5:53 PM

  Their privacy policy doesn't forbid them from just straight up publishing your raw prompts as training data.

  My threat model is that anything I POST to DeepSeek I treat as public to the web, as much as a public GitHub repo is.

• cdolan

  today at 5:48 PM

  That is likely because Deepseek themselves is the only host.

  In 24-48 hours there will be other options I presume

Currently burning money quickly on official deepseek api. They are also increasing pricing starting today. V4 Flash 0731 still feels like the most outstanding model of the past few months and probably to come.

What I care about is whether the model is capable of the tasks I give it at the lowest cost. Right now I'm using Kimi-K3/GLM-5.2/Minimax. Sonnet is great but I burn through the tokens too fast. Opus 5 set to max is amazing and more intelligent than all of us. .998 of the time I don't need that kind of intelligence. I just need the job done.

• okamiueru

  How do you define intelligence? I encounter that kind of sentiment all too often, and I have to assume we go by wildly different understanding of what that might entail.

  • bikemike026

    today at 5:54 PM

    If you read Opus 5's output, it is beyond the comprehension of virtually all engineers and developers. That is what I mean by intelligence. Math, science, and engineering are all contained in one model. We may be experts in one field. The model is an expert in everything that humans know.

Even though cost-per-token is low, Deepseek v4 tends to burn an immense number of tokens to accomplish tasks.

V4 Pro has vision correct?

• trollbridge

If only it supported image input ...

• sinuhe69

  today at 5:11 PM

  Well, one reason is that we always have to work with the quirks of each model. So, a know model is often preferred over a new/unknown one because we have to be vigilant again. (Negative) surprises are mentally exhausting in the long run. IMO, you can work much better when you know the model.

• spacebanana7

  today at 5:09 PM

  In an enterprise setting Chinese models are often discouraged due to political risk. They don't want to need to remove a model that's deeply embedded in their stack. And it's entirely feasible that the US gov bans federal contractors from using them in the next 6 months for example, or that EU AI safety rules effectively ban them too.

  • trollbridge

    today at 5:38 PM

    Then run the DeepSeek or Qwen model on AWS GovCloud, etc., and you won't have any risk of exposure to "China".

    I'm not even sure what "EU AI safety rules" are. Can't people in the EU just use whatever they want?

  • BlackRabbit1

    today at 5:20 PM

    There are EU/US providers offering Deepseek/Qwen/Kimi/etc.-as-a-Service. With zero ties of their infrastructure to China.

    Fully compatible with the well known Antrophic API.

    You only have to replace the URL and your key.

    • odo1242

      today at 5:34 PM

      Based on what the political climate looks like nowadays it's entirely possible the US bans federal contractors from associating with any company that uses the models themselves, regardless of data provenance or where they are hosted. Or they create AI safety rules that make it impossible to release open source models (for example, making it so that closed-source models can be evaluated with a harness but open-source models need to pass the benchmark with the weights alone, which isn't really possible). Or they just declare Chinese models a security risk like TikTok (claiming that the model would be trained to respect Chinese interests).

      It may not be likely but it's definitely possible enough to be something people worry about.
