Anthropic's AI model, Claude, has successfully formalized Fermat's Last Theorem in 11 days, a task that was expected to take humans five years to complete. The theorem, proposed by Pierre de Fermat in 1637 and proven by Andrew Wiles in 1995, was formalized using the Lean programming language. The AI model produced a 13 million-line code and proved 30,300 sub-theorems, a significant achievement that has sparked interest in the potential for AI to assist in mathematical research.
However, the code is not yet suitable for integration into the Mathlib library due to its complexity and lack of documentation.
