Context

ReviewBench is GitHub's attempt to give AI code reviewers a shared test, built around the question its announcement on X puts first: does a reviewer catch the issues that matter without adding noise? That question has two sides, missing real problems and flagging things nobody needed to act on, and a shared lets reviewers be compared on both by running them all on the same pull requests. GitHub says this one is open, contains 219 pull requests across 19 languages, and was shaped by its analysis of 103.9 million pull requests on GitHub. Teams can bring their own code review , evaluate it and submit their results.

The post itself does not say how the 219 pull requests were chosen from that analysis, what counts as an issue that matters, or how a reviewer's comments are scored, so it cannot by itself show how much a ReviewBench score should be trusted. GitHub's blog post sets out the construction, scoring and submission process, and Intel covers it in a separate entry, which is the place to judge the method.
