An advanced version of Google's Gemini model, called Gemini Deep Think, achieved a gold-medal standard at the International Mathematical Olympiad (IMO) by solving five out of six problems perfectly. The model was trained on a curated corpus of high-quality solutions to mathematics problems and was able to produce rigorous mathematical proofs directly from the official problem descriptions. This achievement demonstrates significant progress in AI's ability to reason and solve complex mathematical problems. The solutions can be found online and have been officially graded and certified by IMO coordinators.
