People always forget that back when OpenAI accused DeepSeek of distillation, o1's reasoning process was locked down, with only short sentences shared with the user as it "thought." There was a paper published in November 2024 from Shanghai Jiao Tong University that outlined how one would distill information from o1[1], and it even says that they used "tens of thousands" of o1 distilled chains. Given that the primary evidence given for distillation, according to Bloomberg[2], was that a lot of data was sent from OpenAI developer accounts in China in late 2024, it's not impossible that this (and other projects like it) could also have been the cause of that.
The thing is, given the other advances that were outlined in the DeepSeek R1 paper, it's not as if DeepSeek needed to coast on OpenAI's work. The use of GRPO RL, not to mention the trai

ning time and resources that were required, is still incredibly impressive, no matter the source of the data. There's a lot that DeepSeek R1 can be credited with in the LLM space today, and it really did signify a number of breakthroughs all at once. Even their identification of naturally emergent CoT through RL was incredibly impressive, and led to it becoming commonplace across LLMs these days.[3]
It's clear that there are many talented researchers on their team (their approach to MoE with its expert segmentation and expert isolation is quite interesting), so it would seem strange that with all of that talent, they'd resort to distillation for knowledge gathering. I'm not saying that it didn't happen, it absolutely could have, but a lot of the accusations that came from OpenAI/Microsoft at the time seemed more like panic given the stock market's reaction rather than genuine accusations with evidence behind them... especially given we've not heard anything since then.
