Anthropic has reported that approximately 1,000 agents running Claude Fable 5.2 successfully formalized Fermat's Last Theorem in the Lean proof assistant within 30 hours. This is a significant improvement over a previous attempt in September, which took 11 days and used more computational resources. The agents worked with minimal human intervention, starting from basic prompts and progressing based on intermediate theorem statements. While this formalization does not present new mathematics, it demonstrates a substantial acceleration in the process of verifying known proofs. AI
