🧠 Claude formally proved Fermat's Last Theorem. In 11 days.
350 years after the conjecture, 30 years after Wiles' proof, and now Anthropic's Claude has done what no human had bothered to: a full computer-checked formalization in Lean. 13 million lines of code. 29,500 intermediate theorems.
Several dozen parallel agents, 6 billion tokens, 11 days wall-clock.
Nature covered it. Hard to argue this one's hype.
