MiniMax open-source mathematical proof framework MaxProof, using evolutionary search to push M3 over the gold medal line

Abstract generation in progress
CoinWorld news: MiniMax developer relations lead Ryan Lee announced that the test-time scaling and extension framework MaxProof for large-model mathematical proofs has officially been open-sourced, along with a related technical paper. MaxProof rebuilds mathematical proofs in the reasoning phase into an evolutionary search system, achieving reasoning scaling through verification, repair, and elimination mechanisms. Supported by the MaxProof framework, the MiniMax-M3 model scored 35 and 36 points respectively (out of 42) on the test sets of the International Mathematical Olympiad (IMO 2025) and the American Mathematical Olympiad (USAMO 2026), hitting the gold medal cutoff score in both cases. By integrating the three expert capabilities of generation, verification, and repair, this framework builds a multi-layered defense verification mechanism, successfully transforming the model’s best mathematical proofing capabilities into more stable performance.

Do you have a link to the technical paper? I want to focus on the ablation experiments of the repair strategies.

The idea of combining evolutionary search with the three capabilities is interesting; it seems much more efficient than pure sampling, saving computational power.

MiniMax-M3’s performance is indeed impressive, but IMO’s gold medal cutoff changes every year—so after the official release of 2025 data, we can pop the champagne.

Is it open source? I'm going to check out the code to see how the verification module is designed.
