Browsing and Discovering Problems

Finding beautiful math olympiad problems has never been easier. The platform also includes a random problem feature, so you can dive straight into something unexpected.

MathNet as an AI Benchmark

Beyond being a resource for human learners, the dataset is proposed as a benchmark for AI models. GPT-5, for instance, solved only 69% of the problems — a reminder that olympiad mathematics remains genuinely challenging even for state-of-the-art systems.

Anyone up for some problem solving?
