burny_tech · x · 2026-09-05
Anthropic announced that Claude completed the first formalized proof of Fermat's Last Theorem last month, translating Andrew Wiles' 1995 proof into Lean-verifiable form — a task experts expected to take years.
- Over 13 million lines of code, the largest Lean proof ever written
- Formalizes more than 29,000 supporting theorems the proof depends on
- Formalization enables machine verification of mathematical reasoning via proof assistants
A landmark result for AI in frontier mathematics.
