Google’s AI model gets gold at global math event, OpenAI also claims win

Alphabet’s (NASDAQ:GOOG) (NASDAQ:GOOGL) Google said its AI model won gold medal at a global mathematics competition, while Microsoft (NASDAQ:MSFT)-backed OpenAI also claimed that its experimental reasoning model achieved a gold medal-level performance.

Google said an advanced version of Gemini Deep Think solved five out of the six International Mathematical Olympiad, or IMO, problems perfectly, earning 35 total points, and achieving gold-medal level performance.

“This year, our advanced Gemini model operated end-to-end in natural language, producing rigorous mathematical proofs directly from the official problem descriptions – all within the 4.5-hour competition time limit,” said DeepMinds’ Thang Luong and Edward Lockhart in a blog post.

Last year, Google DeepMind’s combined AlphaProof and AlphaGeometry 2 systems achieved the silver-medal standard, solving four out of the six problems and scoring 28 points.

“We can confirm that Google DeepMind has reached the much-desired milestone, earning 35 out of a possible 42 points — a gold medal score. Their solutions were astonishing in many respects. IMO graders found them to be clear, precise and most of them easy to follow,” said IMO President Prof. Dr. Gregor Dolinar.

Google noted that it will be making a version of this Deep Think model available to a set of trusted testers, including mathematicians, before rolling it out to Google AI Ultra subscribers.

Meanwhile, OpenAI also claimed a gold medal status for its experimental model.

“I’m excited to share that our latest @OpenAI experimental reasoning LLM has achieved a longstanding grand challenge in AI: gold medal-level performance on the world’s most prestigious math competition—the International Math Olympiad (IMO),” said OpenAI researcher Alexander Wei in a series of posts on social media platform X.

Wei said the company evaluated its models on the 2025 IMO problems under the same rules as human contestants: two 4.5 hour exam sessions, no tools or internet, reading the official problem statements, and writing natural language proofs.

“In our evaluation, the model solved 5 of the 6 problems on the 2025 IMO. For each problem, three former IMO medalists independently graded the model’s submitted proof, with scores finalized after unanimous consensus. The model earned 35/42 points in total, enough for gold!” said Wei.

Wei noted that the IMO gold LLM is an experimental research model. and the company does not plan to release anything with this level of math capability for several months.

Google and OpenAI did not immediately respond to a request for comment from Seeking Alpha.

The results marked the first time that AI systems crossed the gold-medal scoring threshold at the IMO for high-school students, according to a report by Reuters.
