That might be true, but it's irrelevant to the current discussion, which is arguing about whether or not Chinese models can do this now. One of the commentators above is arguing that it's not only possible but significantly cheaper (i.e. Chinese models are not only at par with frontier but several months ahead).
Do you really think that if a Chinese model had achieved a significant math breakthrough that it wouldn't be trumpeted to the global media? The "Deepseek moment" was great for China; this would be the same.
Perhaps since the Chinese companies don't have the economy of an entire global superpower riding on them, they can't afford to light $100k+ on fire doing random shit with the hope it'll turn out a research paper.
Why have all the mathematical (and now cryptographic) breakthroughs come from OpenAI and Anthropic?
Is it possibly because the Chinese models are so benchmaxxed they can't make novel discoveries?
