Anthropic's Machine-Verified Fermat Proof Spans 13M+ Lines and Formalizes 29,000+ Theorems

Anthropic announced an AI-produced, machine-verified proof of Fermat's Last Theorem — first proven by Andrew Wiles in 1995, 350+ years after it was conjectured. The formal proof totals over 13 million lines of code and, crucially, proves 29,000+ supporting theorems across areas of math never previously formalized. A landmark result for AI for mathematics: not just reproducing a human proof but systematically formalizing entire mathematical domains.
