Mathematicians evaluate Claude's 13-million-line proof of Fermat's Last Theorem
Over an intensive 11-day run, a multi-agent swarm generated a verified 13-million-line proof, solving a formal verification challenge once estimated to take years.
- Following Anthropic's announcement of the first computer-checked formalization of Fermat's Last Theorem, mathematicians have begun evaluating the verified 13-million-line proof.
- The resulting Lean 4 code contains approximately 13 million lines of code and proves 29,511 intermediate theorems across modular forms and elliptic curves.
- The project was made possible by 'Prove2Me,' a collaborative platform that used a directed acyclic graph to provide a shared memory space for parallel agents.
- The proof was fully verified by the Lean kernel using only its three standard axioms, confirming there are no logical gaps in the formalized proof.
