Science: cracks emerge in Lean certificates backing AI-generated math proofs
neurovium · x · 2026-11-06
Science magazine reports that as AI catalyzes math breakthroughs with proofs hundreds of pages long and nearly incomprehensible, AI companies have leaned on Lean proof-checker certificates to reassure mathematicians. But these guarantees may not be as airtight as they seem—the report exposes cracks in Lean-based autoformalization pipelines, questioning the perceived rigor of machine-verified proofs.
