Anthropic mathematician suggests OpenAI's millennium proof may have been trained on users' math work

Neurogence · reddit · 2026-09-09

Levent Alpoge, the Anthropic-affiliated mathematician behind the millennium problem proof, said 'we cannot rule out that de-identified data derived from their usage of our products helped improve our models' — implying OpenAI mathematicians' Claude usage may have contributed training data. He also reveals he was offered the Millennium Prize to be removed from his own paper, calls the whole saga 'unstrategic and unnecessary,' and says he'd have preferred labs cooperating.
