OpenAI's "Diamond Dump": 722 Papers Claim 63% of 372 Open Math Problems Solved

gleech · x · 2026-10-10

Gavin Leech, Lucca Fraser and Peli Grietzer review OpenAI's mass release of 722 preprints attacking 372 open math problems. OpenAI claims 63% fully solved, including 90 of the "top 500" open problems in mathematics and at least three of Field Medal-level interest. Only 42% come with Lean certificates, 3 proofs were withdrawn, and 14 needed repairs. Average cost: 3 hours of ChatGPT Pro compute per result. Critics note only 10 proofs include prompts, and the 372/4000 solve rate trails the earlier 45% claim.
