OpenAI Model Wins Gold at International Math Olympiad – or Did It?

A Google DeepMind researcher and OpenAI’s former ​​CTO are posing questions about the validity of OpenAI’s claim about its gold-medal score.

OpenAI’s latest model has achieved a gold-level score on the 2025 International Math Olympiad. It answered five out of the six questions under exam conditions, scoring 35 out of a possible 42 points.

The International Math Olympiad is known to be the most prestigious and challenging mathematics competition for high school students in the world. Only about 10% of this year’s competitors received gold medals, and numerous Fields Medalists have won it in the past. Each competitor has two 4.5-hour sessions to complete the six questions without access to the internet or any tools.
