math benchmark
IMO 2025
IMO 2025 evaluates models on the six problems from the 2025 International Mathematical Olympiad, requiring rigorous proof-based reasoning. Following the MathArena methodology, proofs are graded against human expert rubrics by dual strong judge models, with the minimum of the two scores taken as final. Maximum score is 42 points.
