GitHub Copilot Code Review Hits 60M Reviews as AI Handles 20% of Pull Requests

GitHub’s AI-powered code review tool has crossed 60 million reviews, with usage growing 10X since its April 2025 launch. The feature now handles more than one in five code reviews on the platform—a significant shift in how enterprise software gets shipped.

The milestone comes as parent company Microsoft trades near a $3 trillion market cap, with AI tooling increasingly central to its developer ecosystem strategy.

What Changed Under the Hood

GitHub rebuilt Copilot code review on what it calls an “agentic architecture”—essentially giving the AI memory and the ability to explore repositories rather than reviewing code in isolation. The shift produced an 8.1% increase in positive developer feedback, according to the company.

The practical differences: The system now catches issues as it reads rather than waiting until the end of a review. It maintains context across multiple pull requests. And it reads linked issues and PRs to flag gaps where code looks fine alone but doesn’t match project requirements.

“Copilot code review handles pull request reviews and summaries, allowing teams to focus on more complex tasks,” said Suvarna Rane, Software Development Manager at General Motors.

The Quality vs. Speed Tradeoff

GitHub made a deliberate choice: slower reviews that surface real issues beat instant feedback that adds noise. One recent model upgrade improved positive feedback rates by 6% while increasing review latency by 16%. The team considers that an acceptable trade.

The numbers tell the story of restraint over volume. Copilot stays silent in 29% of reviews where it finds nothing actionable. When it does comment, it averages 5.1 suggestions per review—clustered into logical groups rather than scattered across the pull request timeline.

Enterprise Adoption Patterns

Over 12,000 organizations now run Copilot code review automatically on every pull request. Financial services company WEX offers a case study: two-thirds of its developers use Copilot, including the most active contributors. After making AI-assisted reviews the default across repositories, WEX reports shipping approximately 30% more code.

The feature integrates with deterministic tools like CodeQL and ESLint for security and quality checks—meaning AI suggestions layer on top of existing automated safeguards rather than replacing them. Importantly, Copilot’s reviews don’t count toward required human approvals for merging, preserving the human oversight loop.

What’s Next

GitHub signaled two development priorities: deeper personalization to learn team-specific preferences, and two-way conversations that let developers refine fixes before merging. The goal is moving from a one-shot reviewer to something closer to an interactive pair programmer.

Copilot code review requires a paid subscription—Pro, Pro+, Business, or Enterprise tier. Organizations already using the feature can enable automatic reviews on every pull request through repository or organization settings.
