MathArena has tested a few LLMs on the 2025 USAMO, achieving an average score of 2 points out of 42. Even I can score higher than that! Read the paper at https://arxiv.org/abs/2503.21934. Detailed info is available at https://matharena.ai/.

Maybe LLMs won't be taking over our jobs yet.

UPDATE: Gemini 2.5 pro apparently gets 10 points, which is better, but still not high enough to beat me.
