    Fully open models really need to be a big part of the AI future. That includes all source code, open training data, how it's organized, fed to the model, processed, etc. Until that becomes a thing you're always going to be left wondering what exactly lies underneath the closed model you are using, leaving open the possibility for societal manipulation.

      The training data would need to have a permissive license for this to be possible.

        Here me out.

        Decentralized unstoppable storage, combined with decentralized unstoppable training, sorta like SETI for AI training. The seed of this tech already exists with IPFS and others like it.

        We know (some? all?) of the big labs have skirted copyright laws at one point or another. Truly open models would just build on what is publicly available.

        You could sidestep it by running non-permissibly licensed training data that you purchased through an LLM. Legal attitude so far seems to be that this is transformative as long as it's not 1:1. The question on whether or not the end result is copyrightable of course remains controversial and inconsistent, but that question is also fairly irrelevent. You don't get more libre than public domain.

        That's a fair amount of computational and labor overhead mind you, as you'll need to verify and prune the quality of your mountain of synthetic data, but certainly possible.

        Though this assumes the legal system is a rational actor playing by the set of rules it claims to. In fact, I highly suspect you could get very unlucky and get an unfavorable ruling against you, because you stepped on a big pile of money's toes in the process of doing this.

        Eventually we'll just construct 100% synthetic training data that can reliably reproduce pretrains and fine tunes.

        The first broadly useful fully open source models will do this.

        We already have open data / open code / open weights for some domain-specific cases, such as audio models trained on large open datasets, eg. Tacotron / LJSpeech from waaay back in the day, though that is certainly not SOTA anymore.

        Distillation could possibly be considered an early case of this as raw AI outputs are themselves not copyrightable unless humans enrich, filter, or transform them. Granted, that does not handle the cases where the outputs are sufficiently similar to copyrighted original works.

          But how much of that synthetic data still ultimately derives from non-open sources? You'd still have to ask what a clean room implementation ultimately is, depending on how granular or aggressive a large publisher wanted to get about it.

          That said, I don't necessarily disagree with you. Talkie[1] presents an interesting case for it being at least possible to do this entirely on public domain material.

          But even that used Claude somewhere in the course of its training pipeline (it's listed as a contributor on their GitHub), so again, how granular you want to get with that is still a question.

          Where does that synthetic data come from? Magically just started existing?

      I believe Olmo from AllenAi is this

      https://allenai.org/olmo

      Open models can be used/changed for social manipulation too, by anyone, which scares a bunch of people, as opposed to the dark pattern manipulation from Big Ai/Tech

      Why? Sure, I’d prefer it, too, but this is just another GNU/Linux vs. macOS situation: most of us would prefer the first, but actually get shit done on the latter.
      • verdverm 1 minute ago
        we get shit done on the cloud with the former rather than the later

        I personally find the analogy unconvincing, the UX dimension is completely different as I can use the same harness with any model; and the year of the linux desktop is coming soon (tm)

        And that's why companies shouldn't fear opening up, but having both is still a net benefit.
      • zufallsheld 1 hour ago
        Without open-source, there'd be no macOS.. So good thing, it exists.
      • homarp 1 hour ago
        which is why everyone runs docker on mac, to get shit done.

      Money is the issue here, no one wants to fund it.
      • __MatrixMan__ 11 minutes ago
        I'm sure anthropic didn't want to fund the extra "safety" guardrails they put into fable, but they were forced to, else they couldn't release it.

        Sure there are all kinds of problems with that situation. But it still demonstrates that they can be coerced: play nice or don't play at all.

    It is great to see another player introduce a fully open stack. Nvidia's Nemotron is the only other prominent one I know of.

    All that said, the headline claims do not match the self-reported performance. For example, the dense 32B model is significantly behind Qwen3.8 27B (chart towards the bottom of https://ifm.ai/blog/k2). Gemma4 31B is not in the comparison set. This is the most important sweet spot for self hosted open-weight models today and real competition here will be very welcome.

    • baron3dl 30 minutes ago
      https://allenai.org/ has the fully open olmo also
    • xienze 1 hour ago
      They have the 32B listed as "stage 1" with the note "final checkpoint to be released." So, not finished yet. Not sure why you'd release it if it's not finished, but that's the explanation.

      The 7B does look very, very good however.

      • WithinReason 45 minutes ago
        32B performs worse than the 7B model so I'm sure they will improve it

    Seeing this the day all major closed LLMs went offline is quite the reminder of how valuable open source can be.

    A bit off topic, but I think I'm starting to get model fatigue. These come out 10x faster than new Javascript frameworks were coming out 10 years ago (at least new models are far easier to adopt).
    • hungryhobbit 35 minutes ago
      There was a time when every new PC CPU coming out was a giant deal: "Guys have you heard about this new Pentium processor, it's incredible?"

      But over time, more and more people got into the chip-making business, and the big players started releasing more and more chips. Now only the die-hard CPU trackers worry about every new CPU and exactly how it's better ... while everyone else just worries about "which CPU will be good enough at this moment".

      I think models are on that same arc.

      At least this one can claim being fully open to differentiate it

      Just wait until RSI gains enough traction. We'll be compute-limited rather than labor-limited.

    Here’s the link (K2)[https://ifm.ai/k2/] as the originally linked link is a login url.

    The comparisons with other models here are odd.. the other models change depending on the task. It would be far more useful to at least compare against the more recent open models (DS4Flash/GLM53Flash/Qwen38).

    it's funny that the tagline is Radically Open, but you're immediately hit with http login - maybe this was the wrong link?
    • sottol 1 hour ago
      It's not the blog post, but there's some info here:

      https://ifm.ai/k2/

      375 A23B, 36 A4B, 32B, 7B, 3.7B, 0.9B variants.

      > 32B: Ranking among the top models in its class, 32B is our most powerful dense model, balancing capability, adaptability, and local deployability.

      > 7B: The industry’s best-performing model under 10B combines strong software engineering and expert knowledge in a package small enough to run on a phone.

      https://ifm.ai/k2/ seems to work for me.

    i'll believe 'radically open' when the training data ships alongside the weights. until then it's a very fast demo.
    • adrian_b 4 minutes ago
      I just looked on Huggingface.co, and the training data is there.

      For example, 3.3 Tbyte for code reasoning, 4.5 Tbyte for mathematical reasoning, 8.4 Tbyte of pre-train behaviors, and so on.

      I did not compute the sum of the dataset sizes, but it appears to be some tens of Tbyte. Nonetheless, I assume that this amount of training data is more than an order of magnitude less than what OpenAI, Anthropic and the like have used, which must have been at least many hundreds of Tbyte, but more likely several thousands of Tbyte of data.

      Hey its a lot mpre thsn Anthropic which you probably use everyday all day without complaints.

    Frontier. Everything is frontier. K2 not to be confused with the other K2, or K3 that is also frontier.
  • afzalive 1 hour ago
    Not to be confused with Kimi K2. Out of all the names they could've used, they picked one that would be confusing.
    • bee_rider 1 hour ago
      I kind of assumed all the K2 names were puns. K2 is quite tall, so to get to the top of it you have to be really good at hill climbing. Anyway it’s a pretty well known mountain so I don’t think anyone can call dibs on it.

    Nice! can't wait to add these in my local stack and try them out.
  • luckydata 1 hour ago
    both repositories for pre-training and post-training are actually empty... someone might have jumped the gun on the release.
