A 100-page proof for the 78-year-old Hopf problem, initially developed with Claude, has been formalized into 250,000 lines of Lean code by Boris Alexeev. This extensive formalization, reportedly completed in just days with the assistance of Codex, suggests a rapid advancement in AI's capability to handle complex mathematical proofs. The sheer volume of code indicates that no single human may fully grasp all the intricate details of the proof and its formalization. AI
