Anthropic's Claude AI system completed a formal proof of Fermat's last theorem in 11 days, converting the 1995 human proof into computer-checkable code. This task had been expected to take years, and the formalisation confirms the correctness of Andrew Wiles' original proof. The work was done using the Lean programming language, which allows machines to rigorously verify every logical step.
