If you want to believe that the success of Kimi is about distillation attacks, ignore this.

I stil don't understand them. I want the US to "win the AI race" but I have trouble understanding how most of all inventions today aren't "distillations" of past knowledge. Is Anthropic claiming the data they stole as trade secrets?

Agreed. I think when it comes to light that Claude has been known to say “I’m DeepSeek” that everyone has had their hand in that cookie jar. Moreover, paying for API calls hardly seems like an attack; ToS violation to be certain but not in the same category of law as criminal activity like hacking.

wait, is there evidence of this? I've not observed it. It sounds like the kind of thing that I want to be true because it would be hilarious but that makes me suspicious.

Ask it in Chinese

Google is apparently taking a different stance and offering distillation as a paid product https://docs.cloud.google.com/gemini-enterprise-agent-platfo...

You don't get to take distilled model home, it all stays with Google. It's "optimize your costs in our garden" product.

yup, strings are certainly attached when dealing with US Big Tech / Ai

I recommend Fireworks as an alternative

This is actually a well-known phenomenon in ML, called "The Bitter Lesson". > One thing that should be learned from the bitter lesson is the great power of general purpose methods, of methods that continue to scale with increased computation even as the available computation becomes very great. The two methods that seem to scale arbitrarily in this way are search and learning. The full essay is worth a read, it's pre…

I started creating internal models using it, then the Gated Deltanet 2 came out( https://arxiv.org/abs/2605.22791 ), and it seems like an evolution of it in expressiveness. And in our tests it is really better than.

Is it just me or does this read like a re-implementation of LSTMs?

I'm no expert but it seems like a descendent of LSTMs. There's a series of papers which show how to reformulate attention as RNNs which arrives at linear attention. Then they add a decay term to get mamba2. Then they add modified the decay term as like a scale to apply both to the existing state and the new update to get delta net. Then they added a gate matrix on the output to get gated delta net. Then Kimi Linear Attention seems to be gated delta net with a more expressive gate. The Gated DeltaNet paper recaptilulates this evolution decently well. But yeah, it feels like they're starting with the same lego blocks and assembling them in similar shapes to accomplish similar but slightly distinct modules.

>This is a nakedly hypocritical stance, but completely understandable from a company-needs-to-make-money standpoint. No, it's perfectly reasonable once you get down to reality. China is not going to care about IP. That's just a fact. So either nobody cares about IP (at the very last in this context) and any AI company can just do whatever with data, or Chinese companies have to be held up to scrutiny. We don't have t…

why should western AI companies be held to different standards than Chinese ones? Neither of them are your buddy.

They shouldn't be. But the point is, they are. OpenAI and Anthropic are paying many rights holders for access to their data (reddit, NYT, etc.).

So distillation, among other things, allows Chinese labs to indirectly benefit from these arrangements at no cost to them.

I'd kindly suggest that we could also stop calling them "distillation attacks ".

Agreed, "distilled variants" might be more suitable.

Calling them variants is also inaccurate when the pretrained base and architecture are completely different.

Does any expert in the field know whether it is really the case that this intelligence we are seeing with frontier models is an "emerging" phenomena, only coming up when the architecture is scaled? Like isn't it weird that the 1 million parameter model with the same architecture can't solve basic puzzles but suddenly the 1 trillion parameter can conjure up counter-examples for the Jacobian conjecture? It's unintuitiv…

IANAMLE, but there is "grokking" that makes models learn to actually generalize, even after you give them enough parameters that would let them memorize the dataset: https://en.wikipedia.org/wiki/Grokking_(machine_learning) High-dimensional gradient descent behaves very differently than the simplified 3d visualisations we use to demonstrate it, and has lots of ways out of local minima: https://www.youtube.com/watch?v…

Exactly, I was going to suggest the Welch Labs videos on grokking. Especially the newer one at https://youtu.be/D8GOeCFFby4?si=yLI9zzcjsnEELUqy . They are really well done and really eye-opening.

There is a Sanjeev Arora paper "A Theory for Emergence of Complex Skills in Language Models" (https://arxiv.org/pdf/2307.15936) on this subject. The key idea is there is cross entropy (how "surprised" the model is with the "correct" next token, lower is better), some of which is inherent in the language and therefore unavoidable, and the rest is model error, and that this portion of the cross entropy is reduced with scaling.

And as scaling reduces a model's excess entropy, the model can become good at combinations of skills much faster than you would expect if it had to separately see and memorize every combination. They call this "slingshot generalization".
