Mathematics benchmark
IPhO 2025 (Theory) leaderboard
International Physics Olympiad 2025 (Theory). Every model the catalog carries a published IPhO 2025 (Theory) value for, ranked by that value.
The three official theory problems from the 2025 International Physics Olympiad, scored with blinded human evaluation.
IPhO 2025 (Theory) ranking
1 model with a published IPhO 2025 (Theory) value, ordered by that value, highest first. Models the source has not scored on this benchmark are not listed — they are unmeasured, not last.
