Google DeepMind has achieved a major breakthrough in AI performance by reaching gold medal status at the prestigious 2025 International Mathematical Olympiad (IMO), one of the world’s toughest math competitions for high school students. The AI system, a new and improved version of DeepMind’s Gemini Deep Think, scored 35 out of 42 points, solving five out of six complex math problems with perfect accuracy.
This marks a significant jump from last year, when DeepMind’s earlier AI models (AlphaProof and AlphaGeometry 2) earned a silver medal with 28 points.
The IMO’s President, Prof. Dr. Gregor Dolinar, confirmed the achievement, praising the AI’s solutions as “clear, precise,” and often “easy to follow.” That’s a major compliment, given that the Olympiad problems are designed to challenge some of the brightest young minds on the planet.
What makes this feat even more impressive is how the AI approached the problems. Unlike earlier systems, which needed human experts to rewrite the questions into computer-friendly formats, Gemini Deep Think worked entirely in natural language, reading and understanding the exact same problems given to human contestants, and solving them within the official 4.5-hour time limit.
The model achieved this by using advanced reasoning tools, including something DeepMind calls “parallel thinking,” which lets the AI explore multiple problem-solving strategies at the same time, similar to how skilled mathematicians think through different angles before committing to a solution. The system was also trained using new reinforcement learning techniques and a curated set of high-quality math solutions to boost its problem-solving abilities.
Google plans to make this version of Gemini available first to trusted testers, including professional mathematicians, before rolling it out to Google AI Ultra subscribers.
The development comes amid growing competition in the AI space. OpenAI also announced that one of its experimental models hit the same score, 35 out of 42, in the same IMO challenge. With both companies now demonstrating gold-level performance on a human math competition, this signals a major leap forward in AI’s ability to reason logically, handle abstract problems, and produce rigorous, formal proofs.
Google CEO Sundar Pichai described the progress as “just astounding,” while DeepMind CEO Demis Hassabis called it “incredible progress” in AI’s ability to handle high-level intellectual tasks.
While the AI isn’t replacing mathematicians anytime soon, its success opens up new possibilities for AI-assisted research, education, and mathematical discovery, and represents a milestone in machines tackling one of the most human of challenges: creative problem-solving through logic.
