Interesting, thanks for the links! I had read this part of the article: > All competitors, including OpenAI, were limited to identical hardware provided by AtCoder, ensuring a level playing field between human and AI contestants. And assumed that meant a pretty restricted (and LLM-free) environment. I think their policy is pretty pragmatic.
