Alphabet's Google and OpenAI said their artificial-intelligence models won gold medals at a global mathematics competition, signaling a breakthrough in math capabilities in the race to build powerful systems that can rival human intelligence.

The Google DeepMind team participated in last year's IMO competition using an AI composed of the AlphaProof and AlphaGeometry 2 models. This setup was able to get four of the six questions correct, earning silver medal status—only half of the human participants earn any medal at all.

The IMO 2025 is regarded as one of the toughest competitions for high schoolers worldwide to prove their mettle with numbers and equations. The gold medal scoring by the AI models marks a significant breakthrough for the AI technology, and a marker of how it’s redefining its limits daily.
