OpenAI's GPT-5.2 Pro does better at solving sophisticated math problems than older versions of the company's top large language model, according to a new study by Epoch AI, a non-profit research institute.
The model, DeepSeekMath-V2, scored 118 out of 120 points on questions from the 2024 William Lowell Putnam Mathematical Competition, beating the top human score of 90. The model also performed at the level of gold-medal winners in the International Mathematical Olympiad (IMO) 2025 and the 2024 China Mathematical Olympiad. The results are described in a preprint posted on arXiv on 27 November.
Gemini 2.5 stands out from other AI offerings thanks to its multi-agent structure. This design enables the model to simulate multiple AI agents that work together to analyze, test, and refine solutions to a task.
