What this benchmark measures

A suite of IMO-level mathematical reasoning benchmarks from Google DeepMind, whose IMO-AnswerBench component tests models on 400 robustified Olympiad problems (Algebra, Combinatorics, Geometry, Number Theory) with verifiable short answers graded by an autograder.

Rows on this page are sourced from public benchmark artifacts, leaderboard exports, or source-linked model reports. Each row keeps benchmark version, source model name, and available run details attached to the score.

The metric shown here is accuracy. It should be interpreted within IMO-Bench, not compared as part of a site-wide ranking.

No composite ranking
evals.report never combines benchmarks. accuracy on IMO-Bench is its own number — don’t average it with other metrics.
