Best score per model from arena.ai, as Epoch AI copied it. We don’t read that board ourselves yet. Where a model ran with several settings, we keep its best.

Claude Opus 5.5 leads with 1,820, claims included

Best score per model from every source, including labs’ own numbers and claims Epoch AI collected from reports and papers. Labs pick their own settings, so a claim can beat an independent run of the same model.

One system card reports it

Besides launch posts, we read the system cards, model cards and technical reports labs publish with a release. They report far more, including safety and frontier-risk tests.
