Back up what? That distilling from a more capable model into a less capable model pulls the student model's capabilities up? What. Why the fuck is this even a question.
Look up literally any distillation works. Because this is just distillation but on one-hot token chains instead of richer logit KL proxies.
And no, I'm not claiming than you can "close the loop" and get RSI on the cheap just by distilling forever. I'm claiming that distillation is a very cheap way to bring the performance of a less capable model closer to that of a more capable model. It doesn't give you "a more capable model" out of thin air.
Which is why Chinese labs rely on Anthropic to provide that "more capable model" to them. They take the capabilities Anthropic trained for the hard way, and train for them the easy way.
It's a "fast follower"/"improved capability density" trick, not a "singularity tomorrow" trick. There are a few "distillation pump" tricks that get closer to what you have in mind, but they're still more about "extract more training signal out of the same set of data" than about "unbounded RSI".
Okay, you have no data nor evidence nor a paper backing this claim, it's just speculation.
You want to sell me the idea they are spending hundreds of millions to get unchecked Q/As with reasoning redacted and without checks on the output quality to do what exactly?
Have a shallow pointless bunch of expensive data to get slightly better RL? It's expensive and pointless.
Data has shown again and again that synthetic input/output does not benefit models in RL, it may even make the output worse.
Also, you have a giant bias.
The chinese are the only ones releasing models and research papers in the open from which American labs benefit 24/7 (DeepSeek has been copied by all US providers).
And you want to sell me this ridiculous idea of the giant return of spending hundreds of millions on unredacted pointless QAs?
so the way llms work in the first place. training on original research that was acquired the hard way.
