Code Review Bench (Martian)
AI code review tools review pull requests from five large open-source projects. An LLM judge matches their comments to human-verified golden comments.
Offline set of 50 PRs with 173 golden comments, plus a continuously updated online benchmark. It ranks review tools and agents rather than bare models. About 300 GitHub stars.

Qodo Extended (product; model unspecified) tops the leaderboard with 65.1%
Best score per entry from the benchmark's own leaderboard, read on November 12th, 2026. Where a model ran with several settings or harnesses, we keep its best. Names in gray aren't in our model list: fine-tunes, agent systems, products and older models. They don't count toward leaders.
