MA-ProofBench - Undergraduate: leaderboard
MA-ProofBench (2026) is a Lean 4 theorem-proving benchmark dedicated to mathematical analysis. This board is Pass@8 on its 100 undergraduate (Level I) theorems: the share of theorems for which one of eight sampled proofs is verified by the Lean compiler, in percent; higher is better.
Metric: Pass@8 (%) on the 100 Level I (undergraduate textbook) theorems, formal Lean 4 theorem proving: the model writes a complete Lean 4 proof of a formalized theorem, accepted only when the Lean compiler verifies it; Pass@8 over sampled proofs (8 for the proprietary models, 32 for the open models, estimated at 8); higher is better. Source: arxiv.org. Saturation forecast: Around September 2028. 14 models tracked.
