• OpenAI Says a Secret AI Model Cracked Hundreds of Open Math Problems in One Prompt—Mathematicians Want Receipts
  articleas frameworks and tools2026-10-07

  Software that checks every logical step of a mathematical proof mechanically; used to formalize and verify main results of the published manuscripts, though a passing check only confirms the proof follows from the statement as written in Lean, not that the statement matches the original problem or i

• Sharing AI progress in mathematics
  articleas frameworks and tools2026-10-06
