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.
culi5 hours ago
Other than open training data (currently legally impossible), all of this holds for basically every major Chinese-made model. They not only open the weights but publish detailed methodology papers alongside the models in arXiv and even open source the code.

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

Or, we just need to get this over with and declare any digital data findable via the internet to just be public property of everyone. Everything becomes public, besides stuff you keep locally, and there is no difference anymore, it's all just data anyone can use for whatever. A 1 year grace period for everyone to pull stuff off they don't want to be a part of this bright new open era, then we just scrap everything related to intellectual property, copyright and similar stupid stuff, and slap UBI on top of all of it for good measure.

I'd prefer to stay within the [hacker ethics](https://www.ccc.de/en/hackerethics), and protect private data. For non-private/personal data, sure. But individual people need their privacy protected.

Me too, I'm hacker ethics all the way, which is why I'm saying anything network connected should really realize the "All information should be free." dream, and then private data should be far away from the internet, on computers/drives not even connected to the internet. The whole E2E encryption is a ticking time bomb people rely to keep their data safe from others, but nothing that you don't physically have close to you can be truly secret forever, and even then it'll be hard.

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.

If the LLM/AI ecosystem starts actually needing some Person-To-Person (or maybe Agent-To-Agent?) payment system because things actually get smart enough to be useful autonomously, they're gonna need some way to send money/currency around.

echelon10 hours ago
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.
waffleiron9 hours ago
Where does that synthetic data come from? Magically just started existing?
chaosharmonic9 hours ago
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.

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.

xienze9 hours 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.
bluejay23878 hours ago
In this case, the fully open source pipeline is probably as valuable or more so than the weights, so releasing early has some justification.

32B performs worse than the 7B model so I'm sure they will improve it
cogman108 hours ago
My quick review of the 3.7B model (because I was interested) is that it's not to be trusted for coding.
It failed my basic test I like to ask models and generated incorrect code. When prompted about the bug, it preceded to start hallucinating non-existent APIs. After doing that it got caught in a loop trying to desk check the solution that didn't work.
cogman105 hours ago
7B produced 2 answers, 1 was correct though more expensive and the second was incorrect.
The first attempt with 7B the model got stuck in an infinite loop.

cogman106 hours ago
It's actually just a coding interview test that I liked to ask in the past. You can find it and others on leetcode.
The reason I personally like my question is because it's pretty close to some of the real world work we do. It's mostly mundane and easy to bang out, but really easy for someone to do a n log n solution where an n solution exists.
A good example (but not my question) would be something like
"I have a list of People objects with a `first` and `last` name. Write a function which groups together all the People with the same last name in `your language of choice`"
dotancohen6 hours ago
LLMs have a problem with that type of question? I might try it later at home.
cogman106 hours ago
Now a days? No. It's actually getting to be a bad question because they all push out about the exact same answer.
But much earlier they did and, apparently, these really small models still do. At this point it serves as more of a smoke test for me. Success means little, failure means a lot.
dotancohen3 hours ago
Terrific, thank you.
xienze6 hours ago
Not sure a model that small is really supposed to be used for any real coding. At that size you're usually using the model to do simple tasks like summarization.
cogman106 hours ago
To be clear, the question wasn't a complex one. It was more on the level of "could I use this for a fast inline coder" IE, single somewhat simple function question.
I wouldn't have dreamed to use this as an agent model.
7B models of the past have been able to pass this question. I've not tested it on a 4B model until now.

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.

Same for smartphones. There was a time of unlimited hype and secrery around new iphones. Who remembers the story of an iphone 5 prototype left a bar. Journalists were going crazy, people were signing petitions for Apple to not hunt down but instead forgive the employee that made such a grave mistake. People were offering millions to buy the prototype so they can brag they got the new phone 2 weeks before everyone else did.
Or who remembers the dancing disease of 1518, were people would stop what they are doing and start randomly doing the same dance. The lords? Out of their minds. The priests? Terrified the devil had taken hold of the flock! I have come to believe that it was probably some tik-tok like hype trend of doing a fortnite dance while waiting in line for bread and communion. And the energy back then, like now, was off the charts.
Hype and memetic trend seeking encoded deep in human psyche.

I'm glad to see some development in the space of "truly open" models that share training data and other recipes. As the costs for hardware fall over time (hopefully), we should see more possibility in fine-tuning and developing software to inspect the source training material.
Some other open models I'm aware of:
- OLMo
- Apertus
- Soofi
- OpenEuroLLM
- llm-jp
OLMo is perhaps the most famous, and their Dolma training corpus has been reused in other projects. It looks like the K2 training materials haven't been released yet, but I'm interested to see what they did for training "long-horizon agentic tasks". I'm aware of SWE-smith + SWE-gym but I'm guessing there's a lot more out there now.I'm no expert, which is part of why these projects excite me. I'm hoping they can be good projects to learn from as well.

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).
cogman108 hours ago
They are trying to keep the models within the same quant class, which is tough to do since a lot of models aren't distilled to lower quants.
There is, for example, no Qwen3.8 7B.
It is odd to me, though, that they didn't run the same benchmark suite for the various quants.

While the open approach is commendable. The 32b and 36b models are inferior to qwen 3.8 27b, at least according to benchmark numbers. I would have liked to have seen both compared to 27b, not only the dense one. Also would have liked to see more coding benchmarks in the full table.

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.
