IPhO 2025 Theory evaluates whether a model can solve the same three multi-part theoretical physics problems that competed for medals at the 56th International Physics Olympiad, held in France in July 2025. Each problem requires deriving results algebraically from first principles and physical reasoning — not recalling a fact — under the same official mark scheme used for the roughly 400 human student contestants. It is single-turn, text-based (this repository did not confirm whether the official problem sheets also include diagrams), and testing is closer to multi-step quantitative reasoning than to closed-book knowledge recall, which is why this page treats it as a reasoning benchmark rather than a domain-knowledge one.
Three multi-part theoretical physics problems, each requiring worked derivations and numerical or symbolic answers; a model produces written solutions to be graded against the official IPhO 2025 marking scheme, the same instrument used for human contestants' scripts.
