I think most of the comments in this thread are missing the point. It's not about whether it's legal/ethical/etc.

It's about the narrative that "Chinese models are at Fable level". The truth (if correct) is the China continues to copy, and the proprietary US Models continue to lead the state of the art.

There is no K4 without Fable 6, GPT-6. That, matters.

That's simply not true though. Chinese labs very clearly have the entire stack developed and working. Using traces from claude allows them to shorten their training time by some amount, that's it.

Remove Fable 6 and you still have K4 eventually, just 2 months later at best.
