Verifying AI Proofs with Lean: Capability Scales with AI, Immune to Misalignment

harris_edouard · x · 2026-08-06

Discusses the advantages of using formal theorem provers like Lean to verify AI-generated mathematical proofs. The approach has two key features: it gets stronger as AI capabilities improve (enabling harder theorems), and it is theoretically independent of the proving AI's alignment—if the proof compiles in Lean, it is true even if the AI is malicious.
