AI models from OpenAI and Google DeepMind achieved gold-medal scores in the 2025 International Math Olympiad (IMO), one of the world’s oldest and most challenging high school-level math competitions. The results highlighted the rapid advancements in AI systems and the fierce competition between Google and OpenAI in the AI race.
Breakthroughs in AI Reasoning Models
Both companies entered “informal” systems into the competition this year, allowing their AI models to ingest questions and generate proof-based answers in natural language. They both correctly answered five out of six questions on the IMO test, outperforming most high school students. These gold-medal performances represent breakthroughs in AI reasoning models, particularly in non-verifiable domains with ambiguous solutions.
Controversy Surrounding OpenAI’s Announcement
However, controversy arose when Google questioned OpenAI’s announcement of its gold-medal performance, criticizing the premature disclosure before the results were officially verified by IMO. Google waited to announce its results out of respect for the competition’s participants and the organizers’ evaluation guidelines. Despite the debate, the bigger picture remains the impressive improvements in AI models from leading labs like OpenAI and Google, showcasing the rapidly evolving landscape of artificial intelligence.
