Group 1 - Alphabet's Google announced that its AI model, Gemini Deep Think, achieved a gold medal in the International Mathematical Olympiad (IMO) by solving five out of six problems, scoring 35 out of a possible 42 points [1][2] - The model demonstrated end-to-end reasoning in natural language, providing rigorous mathematical proofs within the 4.5-hour competition time limit [1] - Last year, Google's DeepMind's AlphaProof and AlphaGeometry 2 system only achieved a silver medal, solving four problems and scoring 28 points [1] Group 2 - OpenAI also claimed that its experimental reasoning model reached gold medal status in the IMO, solving five out of six problems and scoring 35 points [2][3] - The evaluation was conducted under the same conditions as human participants, with two exams of 4.5 hours each, without the use of tools or the internet [2] - This marks the first time an AI system has crossed the gold medal scoring threshold in a competition aimed at high school students [3]
