New framework uses Lean proof assistant for AI math verification

Researchers have developed LeanPRM, a novel framework that leverages the Lean proof assistant to generate step-level correctness labels for AI-generated mathematical proofs. This system pairs natural language proofs with formal proofs, allowing Lean to automatically label each step. A Qwen3-4B model trained on LeanPRM demonstrated a significant improvement in accuracy on proof verification tasks, outperforming models trained on existing datasets like PRM800K. The framework's ability to create labels without human annotation offers a scalable solution for improving the reliability of AI-generated mathematical reasoning. AI

IMPACT This research could significantly improve the reliability and trustworthiness of AI systems generating complex mathematical proofs.

    LeanPRM: Lean-Grounded Process Supervision for Natural Language Proof Verification

    arXiv:2610.17697v1 Announce Type: cross Abstract: AI systems now write long and difficult mathematical proofs, and checking their step-by-step validity is becoming a bottleneck. A learned verifier could check proofs cheaply, but training one requires a correctness label on every …
