    Hilarious sentence: "DeepSeek-V4.1-Flash-1017 is a minor update to DeepSeek-V4.1-Flash, delivering substantial improvements across reasoning, coding, agentic tasks, and visual benchmarks." (emphasis mine)

      They changed how it works substantially. I think it should be 4.2.

        But with that version number, it's not a "minor" update! It's a patchlevel update! -Engineer

        Strictly speaking, it just shows they aren't marketers. Bad copy doesn't tell us anything about their engineering skill.

          It's not a bad copy, or at least that's not what the person you responded to is insinuating.

          Deepseep-v4.1-Flash-1017 is a minor update. A major update is something like Deepseek-v5-Flash.

            FWIW, GP didn't write "a bad copy" but "bad copy", referring to the marketing sentence quoted by OP, rather than the model that was just released (as I presume "a bad copy" sounds, maybe like it's called that because it's [again, presumably] distilled?). "Copy", especially in a marketing context, is a written message.

      Minor updates can provide substantial improvements sometimes, it really depends on the specifics.
      • varispeed 18 minutes ago
        Remember when we were dumbfounded why our service is slow despite having implemented quite robust caching mechanism. Turns out simply the flag that enables it was hardcoded to false. So it was minor update (changed flag to true), but provided substantial speed up.
    • jaynetics 5 hours ago
      It's not really contradictory, minor changes can have major effects.
      • mdp2021 5 hours ago
        So they meant a "small" update - "conservative", "inexpensive"...

        An example when using a less frequent term actually reduces specificity.

      It's a bit refreshing to read updates from an AI lab without bullshit doomerism and overwhelming sense of self-importance from shit like OpenAI and Claude.

      Also, DS is an excellent model.

      I'm at 1 trying to get to 10. I move to 2. Minor update. 100% improvement towards goal.

      These are not mutually exclusive.

      That is how exponential functions work. Improve every aspect of a system with 1% and you may get easily 50% more performance.
    • vrganj 4 hours ago
      It's about playing to two different audiences.

      The CCP requires extensive certification for new major releases, to make sure a model doesn't do anything they don't want it to.

      To get around this, Chinese labs only bump versions when they have to and usually claim it's a minor update.

      Then on the other side, they're obviously trying to market to the tech crowd...

    It passed my threshold for not caring to try new models back with DS4, I use it for literally everything. Announcements of new models in the series always feel curious, because it doesn't really feel like there's much left to fix that would improve on what's already there for any task I know of.

    It's a bit like obsessing over patch releases of some software after a major upgrade already solved the original problem long ago.

    • xiphias2 4 hours ago
      I have quite the opposite experience: I can do any concrete coding change with any model, but the intelligence limit just doesn't go through more complex debugging examples.

      And then when I try a smart model, like Astra medium and it solves it (I had a firmware bug in my new laptop where I couldn't charge through USB-C) on the first try (altough with a repo already having lots of information about the hardware/firmware/debugging programs/traces), I realize how much time I'm losing on the few examples that the less intelligent models are just not able to debug and solve.

      • jck 2 hours ago
        Very cool!

        Is your laptop something like framework which has open source firmware?

        I(and many other people) have a similar issue with usb-c charging not working consistently. I've been meaning to try one of these new smart models to help me debug the issue.

        • xiphias2 1 hour ago
          ASUS Zephyrus, but it was able to reverse engineer the ports and I was able to download the firware from the controller itself, write an emulator that emulates running the firmware on multiple controllers with different instruction sets (the USB Power Delivery controller is RISC-V) and the communication between them. Also it found out how to read the communication buffer that was on the devices for debugging, which helped it understand the USB data packets that were doing the handshaking and voltage/current negotiation.

          I had to reboot my laptop a few times though until I got to this, but it was a fun experience anyways.

          At this point open source isn't as much advantage as long as the firmware is not encrypted :)

        Also they can work in completely new domains, like Astra and Opus 5.5 starting to be able to use something like Blender. Currently they still often do horrible topology and basic UV mistakes, and the animations are really bad, but who knows where they’ll be in 5 years.
        • oefrha 1 hour ago
          I don’t think these are completely new domains in training. Like I’ve taken up offers to help code up AI training material just to see what they’re up to and get a sneak peek at how the sausage is made, no idea who these front companies are working for of course, but they pay for all kinds of fringe cases and Blender wouldn’t even be considered fringe in what I saw at the beginning of the year. (I was only there to observe, never submitted anything, so I didn’t betray you guys by helping train your replacements.)

      Speed and price. You should try the 4.1 Flash on one of the fast providers. It's pretty crazy how fast this model works, and it's great for iterative software development because you can steer it fast to where you want to go.

      https://www.lithosai.com/

      https://www.coralbricks.ai/

      • swiftcoder 4 hours ago
        How are these high-speed providers close to matching the API rates from deepseek?
        • pimeys 4 hours ago
          Seems that V4.1 Flash is quite cheap to serve. Especially how it implements the cache, meaning the cache pricing can be very low depending on how you implement it in your inference engine.

          Depends on your use case. But if you do software development with a harness such as oh-my-pi, your cache rates are probably somewhere above 98%. Coralbricks has free cache reads, meaning it's much cheaper than the Deepseek API rates.

          Lithosai is more expensive especially in the ultra tier. It's if you want extremely snappy and fast responses, which is important e.g. for a personal assistant where every second counts.

          If you generate a lot of output, you're better off with the Deepseek API rates.

        Where does one even get decent ZDR provider? I'm wary of sending sensitive data but not at a scale where I would build my own machine.
        • therealpygon 2 hours ago
          You just search around, or heck, just ask Google for inference providers that are ZDR and whatever else you want. Just make sure to read their terms/privacy and review the security center. You will have to request access if you are wanting to get into the deeper details.

          Outside of major players like Amazon/Google which have compatible offerings available, I believe together.ai, fireworks.ai, and deepinfra.com are, as best as I can tell, US-based (if that matters in your situation) SOC2/HIPPA/ZDR. Each of them offer serverless model hosting with caching, which is going to be the cheapest overall. Most of them also offer private AI deployment which is more expensive but your entirely own instance. Some of them more heavily quantize their models (deepinfra) so take that into your workload considerations. I included deepinfra because they tend to have some the new models sooner than others or have models the others don’t (like mimo). IMO, together > fireworks > deepinfra.

          However, you’ll have to keep in mind that for true ZDR you give up caching which increases your inference costs, so it depends on how “Zero” you need the zero to be and on what timeframe. If you just don’t want your data being trained on, normal use is fine imo. If you are working on something actually sensitive (like, because of NDA agreements and such), then they might not be the right choice and you may be looking at more expensive offerings or building a machine.

          One note: you have to pay attention to the source of the inference. Many (similar to open router) offer models that are pass-throughs to a providers API, but they are pretty clearly marked. Just make sure the model is marked as serverless when evaluating new ones. This is where a proxy comes in handy so you can prevent your LLM from accessing a different models from the specific ones you’ve vetted.

      What about "good governance"?

      Does it have zero hallucinations? Does it reflect thoroughly on every single idea it uses, verifying its solidity?

    • mmoustafa 5 hours ago
      definitely could use less thinking time and lower token usage, which is what this bump is focused on
  • jononor 5 hours ago
    Above GLM 5.3, nice! That is a very capable model. I do wish that we will see some smaller "flash" models again though - running this one locally is tough (very costly).
    • LaurensBER 5 hours ago
      For comparison, close to Opus 5. Far behind Sol 6.1 and Opus 5.5.

      Probably a pretty decent model for 90% of the usecases!

      I've been doing a lot of hobby work with GLM 5.3 Flash and I can count the amount of times that I need a stronger model on two hands.

      I have access to unlimited tokens at works and Opus is great but also often overkill if you know exactly what you need.

      • egeozcan 5 hours ago
        I use Opus for planning, through API on medium thinking, it doesn't cost anything significant and the rest can be happily done with deepseek or glm flash. Using sol 6.1 for review loops at the end. All running on pi.

        A very complex task tends to cost like 10$ max. It's comparable to a subscription with enormous flexibility.

        It's a steal.

      • cromka 3 hours ago
        Honestly, I don't know what people see in Sol 6.1. Opus 5.5 is so much more inteligent, as in proactive, avoiding stupid mistakes, where it contradicts itself, ignores the context. Sol 6.1 has a gold-fish memory, it's as annoying for me to work with as Opus 5 was.
        • cjbgkagh 3 hours ago
          You can override the context length of Sol to 1M
          • cromka 54 minutes ago
            That's not actually the problem. It forgets the instructions from 15 minutes ago, without context compression involved in-between.
          • joshstrange 2 hours ago
            Without this change I hated Sol and was burning tokens way faster due to all the forced compacting.

            Since making this (obscure/hidden) change I enjoy Codex much more.

            • cjbgkagh 1 hour ago
              The work I do cannot fit in 256k so it was just relearning the same things over and over again while making zero progress. AFAIK the 1M burns tokens at twice the rate but I use Sol on medium as the work I'm doing now needs more memory than it needs intelligence and it's working great. I use Opus 5.5 for the stuff that needs stronger intelligence.
    • minraws 4 hours ago
      By next year we will likely see GLM 5.3 level performance in Qwen 4 MoE models that can run on most higher end consumer systems.

      I don't think there is a reason to care about any of it, just get a few dollars on a few openrouter or similar platforms and just use the models for now, wait for cheaper models that are good enough for you to become available for your hardware.

      Sure you might never see frontier performance on consumer hardware but do you really need that though? Does anyone? And if you ever do just get a 30-day sub for that work, and cancel it.

      • jononor 1 hour ago
        Yeah performance at a given compute budget will likely continue to improve.

        We are running Qwen 3.8 27B FP8 with 4x 5060 16gb at the office for a small development team. It is doing pretty well for implementing backend and frontend tasks, and is already useful. In 6 and 12 months from how I expect it to get even better. Some planning is still done with a stronger model, but even that is maybe not strictly necessary.

    • Pragmata 5 hours ago
      Cant you run it on a pair of DGX spark? Sure it's expensive now, but at the initial retail price that was what, 8k in hardware? Not exactly unachievable
      • bashtoni 5 hours ago
        No, this is not a small model. I believe 4x Sparks is possible but 4.1 is pretty big for a flash model.

        MiMo 2.6 Flash is the most capable model you can currently run on 2x Sparks without resorting to a quantised version of something.

        • Pragmata 5 hours ago
          I meant quantized. You can get an EXL3 quantized version thats almost the same performance.
          • bashtoni 3 hours ago
            My experience running quantised models is that they look the same at first but are all noticeably worse once the context size gets beyond anything trivial.
            • Pragmata 2 hours ago
              I've tried both 2bpw and 3bpw quants for QWEN3.8 27b, and while i do notice a difference in terms of higher rates of getting stuck in loops, they are both reasonably usable.

              Are they as good as opus 5.5? No.

              Are they about on par with opus 4.6? Yes.

              The long run tasks i run seem to be about the same level of quality, though there are obvious differences in model styles, token budgets, etc....

        Yeah, I had a somewhat odd conversation with a Chinese acquaintance last year when she got to talking about how America sees China. Her point was that, "How am I not free? I can do whatever I want, go where I want, buy what I want. I can talk to you and say whatever I want; nobody is here listening to me."

        The fact that she can't call Xi "Winnie the Pooh" on Douyin wasn't something that occurred to her, or maybe that she was aware of at all. I didn't ask. I don't like to get into these discussions when I'm in China.

        • computerex 3 hours ago
          There is no such thing as “free speech” anywhere. It’s all a spectrum and the Americans in particular are indoctrinated. It’s a red herring to distract from the real social issues. People in America have some of the worst healthcare in the world. But hey at least we have “free speech”.
          • foobar10000 1 hour ago
            Fixing healthcare or economic policies is typically an act of congress type of thing - not even an amendment. Large popular support - and it can be fixed. Fixing freedom of speech or the ability to vote at all - once it is gone - usually takes a price payed in blood. Sometimes rivers of it.

    So is this the first model that passed China's new export controls introduced yesterday?[1] It goes live November 15, but temporary pre-registration requirements took effect immediately after the announcement, ~20h-ish ago.

    • yorwba 43 minutes ago
      Presumably they registered, but that doesn't mean the model passed through export review. It just means that some bureaucrat now has the opportunity to check the product characteristics they reported and decide whether that kind of thing should be allowed for export or not. (Though with the weights out in the open, that's maybe a bit pointless.)

        OpenAI's models -- and even Google's Argon -- have particular niches where they shine. For GPT-6/6.1, it's 3D modeling; Astra is hands-down the best at making .step files, Blender files, etc. For Argon, it's natural language writing and everything that hooks up to Google, e.g. search and maps-based itinerary planning.

        Anthropic and DeepSeek (+ GLM) are definitely solving coding, though!

        They're all quite different tools.

        • Kurtz79 4 hours ago
          Artificial Analysis recently released a dedicated 3D benchmark, where Astra lags behind both Opus and Sonnet 5.5 (and yes, open weight models seem to be quite far behind).

          https://artificialanalysis.ai/articles/aa-3d

          • A_D_E_P_T 4 hours ago
            Interesting!

            For me it's large files in Blender (in some cases >400MB), mostly, where Astra excels. I gave it a look, but I don't know if the benchmark encompasses that sort of thing.

            .step files are simpler pieces of straightforward code, so it makes sense that Opus and Sonnet 5.5 do very well...

          • swiftcoder 4 hours ago
            its unfortunate they didn't include deepseek in the initial batch of benchmarks
      • freakynit 5 hours ago
        I believe these are the last sets of super-high-end models available to public (open or closed).. these companies probably will now start to withhold top-of-the-line models for themselves, governments, and their super-high-paying partners only.
        • A_D_E_P_T 4 hours ago
          That hasn't been the way to bet. DeepSeek and the other Chinese firms show no signs of slowing down, so if OAI and Anthropic halt releases and "pace the frontier" they'll just fall behind. (And there's a chance that high-end AI will become fully commoditized, which suits DeepSeek just fine.)

          Besides, Fable 5.5 is reportedly releasing within the next few days, probably on Tuesday...

          You can in contrast get far more done with $20 worth of deepseek api spend. No comparison.

          i have a feeling that Sol is just Astra low, but with lowest possible priority on the compute.

            I believe it's Astra quantized. It was briefly named astra-lite.
