A review type's best model is its highest-F1 IonWarp model graded on every PR. Two models that show the same F1 are a tie, and a tie goes to the cheaper one, then the faster one. Review times come from runs on Sep 8–24, 2026 (models). Code Review's PRs and labels come from the independent Martian code-review-bench; every other review type uses provisional labels IonWarp scoped itself. Open a review type for every model and app, ranked by Reviewer Score.
