An OpenAI Model Reportedly Found a Counterexample to an 80-Year-Old Math Conjecture

In one of the more quietly extraordinary claims of the week, OpenAI reportedly demonstrated a model finding a counterexample to a longstanding mathematical conjecture — a result that, if verified, represents a genuine novel discovery.

Buried among product updates and funding news, both @oscarlau and @ainunnajib flagged that an OpenAI model helped find a counterexample to a mathematical conjecture that had stood for roughly 80 years. Details in the briefings are sparse — neither names the specific conjecture nor describes the verification process — but the claim, if substantiated, is one of the more significant demonstrations of AI-as-research-tool to date.
