    The best open models today have been “good enough” to do most knowledge work for a few months. This might be the first US one good enough too. That’s a big deal.

    Open weight US based Opus 5.5 within 12 months.

      Inception Mercury 3 and Particle-1's model are also good.

      (I am assuming Inception is an American company, not sure TBH)

        May I add Poolside (Laguna S) to this? Used them extensively during their free trial (sadly now apparently over).-

      • ray__ 9 hours ago ago

        Agree, Mercury 3 is one of my favorite models right now...the speed is such a quality of life improvement.

      • martincsweiss 8 hours ago ago

        Really? I'm surprised. What do you use it for?

        My read on Diffusion LLMs has been that it's cool tech, but only useful for things like like code autocomplete or editing a block of text.

        They don't beat autoregressive models on quality per compute, assuming you are serving lots of users and can batch requests.

        • serf 8 hours ago ago

          MoA schemes that use proposers/task-separation/supervisory roles can still benefit from very fast diffusion models like mercury, the overall speed doesn't have to be bottle-necked by the slowest model -- that depends on the arrangement it's deployed in.

          but to your point , yeah diffusion models can be kind of brain dead without proper coaxing.

          my ideal arrangement is a smarter/bigger model supervising lots of proposals from diffusion models. The diffusion models spit out a big proposal each, the bigger model can vet something as minor as the headline or filename for each proposal, time still ends up being saved.

      • freakynit 7 hours ago ago

        Sorry to put it bluntly, but, Mercury is sh*t in comparison. And I have genuinely tried a few times to use it since the speed is so good. But nop.. it just isn't there.

      • johnshahbazian 6 hours ago ago

        For my own purposes, I found Mercury Decide to be excellent. Better than Jev at what I threw at it. Inception did a really great job with it.

        • flipbrad 4 hours ago ago

          Thanks for your review, 15 day old HN account that likes praising Mercury services.

      > Open weight US based Opus 5.5 within 12 months.

      Seems unlikely. Maybe open weight at all near there? That'd be great.

      • wolttam 9 hours ago ago

        People say this about the frontier every time, and the open models catch up in a matter of months every time.

        • kadoban 9 hours ago ago

          The open models catch up, the _US_ open models catch up much more slowly. Different incentives and cultures.

      • p-e-w 10 hours ago ago

        Why does that seem unlikely? The difference between frontier and open weights has been much less than 12 months for a while now.

        • satvikpendem 9 hours ago ago

          US open weights are much worse, way more than 12 months apart compared to frontier.

        • kadoban 9 hours ago ago

          > Why does that seem unlikely? The difference between frontier and open weights has been much less than 12 months for a while now.

          Frontier and open weights? Yes.

          Frontier and _US_ open weights? No.

          I'd expect a US open weights provider to suddenly get bought or go non-open if they get near Opus 5.5 anyway.

    • josh-wrale 8 hours ago ago

      Muse Glimmer is pretty good.

      • BOOSTERHIDROGEN 6 hours ago ago

        Could you give some examples what makes them good, thanks

    • walrus01 6 hours ago ago

      Things have been remarkably "not terrible" since approximately the release of Laguna S 2.1 a while back in early summer 2026, which is now outdated within the past 6 month time frame by other, better non CN open weight models.

      I'm not saying that any of them are to the level as a deepseek v4.1 flash 1017 or similar but they're catching up. The most recent huge mistral release is also grounds for an optimistic view.

    • agentdev001 8 hours ago ago

      I give it 2.

    • gigatexal 7 hours ago ago

      That’d be the inflection point I’m waiting for!

  • epsteingpt 10 hours ago ago

    It's a nice, domestic open weight model.

    Without hundreds of millions in 9 days a small team is producing a model that can beat DeepSeek 4.1 and a platform to tune it.

    Optimistic for the future.

    • alexandra_au 4 hours ago ago

      It doesn't beat DS v4.1, and they have so much more compute capacity than any Chinese company, yet still cannot even beat MiniMax M3.1 Flash (220B) despite having 2.7x more parameters (596B).

      • perks_12 9 minutes ago ago

        I wouldn't bet on the numbers of compute reported by Chinese labs. Those Singapore Nvidia orders had to go somewhere.

    • explosion-s 8 hours ago ago

      Correctly if I’m wrong but isn’t inkling made by a very well funded startup from an ex - OpenAI exec iirc?

      • arcticbull 7 hours ago ago

        Yes, Mira Murati's Thinking Machines. They are apparently trying to raise $5B at $40B, after raising $2B at $10B last year.

    • markasoftware 7 hours ago ago

      Not beating dsv4.1 at all

    • lifeisloving 8 hours ago ago

      If you cant beat Deepseek on price im not using it. I actually dont care about beating DS in capabilities, I dont think you need more intelligence than Deepseek for 99% of the things people work on, and I dont want LLMs to do everything, that kind of defeats the point. I just need a smart fuzzer and to offload some tedious busy work.

      So why should I pay for 3-20x more for a few small percentage points in preformance. (I would prefer DS did some things better, but largely I can force my desired behavior), but I could only have access to Deepseek 4.1 and still beat almost everyone using opus/fable/astra on a productivity basis, I need automation tools not "do my entire job so Im worthless tools", and DS has already more than gotten there for me.

    • ares623 4 hours ago ago

      Are they distilling from the big labs or Chinese labs at all? In that case isn't it $1 trillion frontier CAPEX + Inkling's costs for the total costs.

      "I bought this house with my own savings plus a small million dollar loan from mum and dad."

      • swid 3 hours ago ago

        Everyone is building on everything that comes before.

        Houses are not built from scratch either. The know-how, power, water, roads, materials…

        • ares623 3 hours ago ago

          Yes, and the sum total of those costs (that makes _some_ economic sense) end up on the total house price.

          Is the same true for distillation?

  • itkovian_ 8 hours ago ago

    The most important thing here is training was entirely nvfp4 - this is best model by far that has ever been trained in that precision and explains why they were able to do it so fast

    • boredatoms 5 hours ago ago

      Oh nice they’ll run well on sparks

      edit: nm I see its a bit big

  • a11r 10 hours ago ago

    Very refreshing to see benchmarks where the reporting team is not the clear winner. They are claiming to be better than GLM 5.3 flash, which is impressive if it holds up outside of benchmarks.

  • tcdent 10 hours ago ago

    Is it SOTA yet? No. Are the domestic open weights labs demonstrating incredible velocity? Undeniably.

    • bashtoni 10 hours ago ago

      Distillation is the tide that lifts all boats

      • epsteingpt 10 hours ago ago

        Imagine if Mira Murati and John Schulman actually know what they're doing?

        • tcdent 10 hours ago ago

          Given the time to market and the date in which these labs were founded, I find it far more likely that the lag was representative of them establishing proper internal (RL etc) tooling.

    • bensyverson 7 hours ago ago

      Seems to be pretty close to SOTA on design. I’m excited to try it out with my agentic design system.

  • cauliflower99 2 hours ago ago

    As someone who knows nothing about wine except I like drinking it - that wine test is fascinating.

  • syntaxing 10 hours ago ago

    I can’t seem to find the cost? The craziness of deepseek flash 1017 is how ridiculously cheap it is for how capable it is.

    • Bolwin 10 hours ago ago

      AA lists it as $0.30/0.03/1 and cost per task is $1.18, about double that of deepseek

      • syntaxing 9 hours ago ago

        It’s about 2-3X more expensive so about the same token efficiency as 1017. I can see this being a good option for the US.

      • kadoban 10 hours ago ago

        Wow, that's pretty good.

  • ddxv 10 hours ago ago

    This is amazing! Can't wait to trying this out. Also, crazy that I found this on LinkedIn with more upvotes and discussion than the HN thread has.

  • maelito 4 hours ago ago

    Looks better than mistral 4 on all benchmarks ?

  • Neywiny 9 hours ago ago

    I feel like this is a dumb question, but why are we spending any effort on wine comparisons? Is there a way to get rid of experts on these to just be ones for code?

    • kccqzy 9 hours ago ago

      What if your coding project is related to wine? So you would want facts about wine to be inside the weights, not through web search.

      • Neywiny 9 hours ago ago

        If it was about wine, why would I want one with a training data cutoff? I'd much rather have one that can query a database about wine

    • randomblock1 8 hours ago ago

      It's not like they're training on that. That's just a good showcase of how the model is good at generalizing & understanding (not benchmaxxed). You might want something similar to these experts for tasks like detecting anomalies or discoloration or whatever.

      • Neywiny 8 hours ago ago

        Source they didn't train on it?

    • XenophileJKO 7 hours ago ago

      Just looking through the benchmarks, the model seems to be very high on visual/spatial capabilities. So I assumed they just tried some hard tasks on it and was surprised by wine identification and thought it was surprising that it could identify wines.

  • jazzyjackson 10 hours ago ago

    I don’t like it. Poor form to squat on an old companies name like that, one which has a rich legacy in AI. I know the trademark was cancelled so all I can say is I don’t like it.

  • barrenko 2 hours ago ago

    They should buy the pleias team and just mog everyone.

  • AnthonyR 2 hours ago ago

    I like the presentation on their website! Super well done

  • alexandra_au 7 hours ago ago

    Damn their last "Inkling Small" model was only 266B and now this is more than double.

  • ygouzerh 4 hours ago ago

    Interesting, I sent the same wine testing example to Claude Opus 5.5 medium, and it failed, where Inkling 2 Small succeed.

    • colingauvin 9 hours ago ago

      You could probably run a Q2-Q3 with 2x DGX Sparks. So...$12k at today's prices. Plenty of folks are running DS 4.1 Flash with Strata and some GPU + bulk in system memory. Maybe more like $3k-$4k? But speeds come down quite a bit.

  • singpolyma3 9 hours ago ago

    So basically comparable to DS4.1? But why bother to make something we already have?

    • nullbio 4 hours ago ago

      I would hope that the American models aren't benchmaxxed to hell like all of the Chinese ones are.

    • multisport 9 hours ago ago

      Because its american.

        • reasonableklout 9 hours ago ago

          Sovereign open source AI is a real thing, lots of companies want to own their own intelligence but also don't trust the models coming out of China.

          • singpolyma3 8 hours ago ago

            Why would you trust anything coming out of USA?

              The vast majority of users on this website wouldn't be trusting something coming out of the USA, they'd be trusting something in the USA.

            • nozzlegear 7 hours ago ago

              Do you mean to ask why non-American companies would trust anything coming out of the USA? Because American companies tend to have a lot of trust for other American companies.

  • alfiedotwtf 3 hours ago ago

    Looks awesome, but dang a bit too big for my machine.

    … I can’t wait for custom resizable models!

    FWIW: like the Sims where you have certain levels where you move one up and others non-linearly go down e.g. Speed, Intelligence, Conciseness, determinism, trainability
