Claim

An internal OpenAI model called Astra cracked ten problems open for a decade or more, from sphere packing to Connes's rigidity conjecture, formalizing each argument in Lean, with Noam Brown noting all ten proofs cost under $2,000 at API prices.

Reported metric: 10 problems, <$2,000

Reporting date: (not necessarily the event date)
