Project
GitHub Copilot's AI reviewer for pull requests and IDEs, which analyzes code changes and leaves line comments and an overview assessment ahead of human review.
GitHub missed its September 30 goal to deploy every production service in Central US, with 120 of 160 there by October 7. Primary MySQL databases are further behind: 13 of 51 had moved, according to GitHub's availability report.
Reality
GitHub's ReviewBench grades AI code reviewers on 219 pull requests from 187 open-source repositories, counting real issues found and false alarms raised. Security teams get a shared, repeatable check before letting a bot gate a release, on a test GitHub also uses to tune its own Copilot reviewer.
Reality
GitHub released ReviewBench, an open benchmark that scores AI code reviewers on 219 pull requests from 187 public repositories in 19 languages. Buyers can rerun any reviewer on the public dataset and published judge, though every score depends on one LLM's view of what counts as relevant.
Reality
Approvals are off by default and admins can fence them to specific file paths, so the decision landing on engineering leads is how many human sign-offs a merge still needs once a machine can supply one of them.
Reality
GitHub's own docs say Copilot always submits a Comment review. A governed change has four checkpoints, and the one holding authority is still branch protection.
