Mathematics benchmark
USAMO 2026 leaderboard
United States of America Mathematical Olympiad 2026. Every model the catalog carries a published USAMO 2026 value for, ranked by that value.
The premier US mathematical olympiad competition, featuring proof-based problems that require deep mathematical insight and rigorous argumentation at the highest competition level.
USAMO 2026 ranking
3 models with a published USAMO 2026 value, ordered by that value, highest first. Models the source has not scored on this benchmark are not listed — they are unmeasured, not last.
| Rank | Model | Provider | Mathematical proof construction |
|---|---|---|---|
| 1 |  Claude Mythos 5 | Anthropic | 97.6 |
| 2 | Claude Opus 4.8 | Anthropic | 96.7 |
| 3 |  MiniMax M3 | MiniMax | 85.71 |

Rows are ordered by the value United States of America Mathematical Olympiad published, highest first. The source does not state whether a higher value is the better result, so this page does not either: for a benchmark that measures a rate of failure, read the table from the bottom.
