AI impact

See how pull requests assisted by different AI coding tools — or no AI tools — perform across metrics like throughput, cycle time, batch size, and review time.

The AI tools → AI impact page helps you understand how pull requests assisted by different AI coding tools — or no AI tools — perform across metrics like throughput, cycle time, batch size, and review time.

This makes it easier to answer questions like: Is AI-assisted work moving through your system faster or slower? Which teams benefit most from AI tools? How are quality indicators responding to increased AI usage?

Available comparisons

First, use the tabs to select the comparison: AI tools, modes, or AI used. This defines how the pull requests are grouped and which additional configurations you have available. The structure of the page is the same for all comparisons.

AI tools

Compare AI tools against each other: GitHub Copilot vs Claude Code vs Cursor vs everything else. You can select which modes are included in the comparison. There's also an option to include only high-confidence matches in the local changes (editor/CLI) mode.

Modes

Compare AI tools modes against each other: local changes (editor/CLI) vs cloud agent vs review agent vs everything else. You can select which AI tools (GitHub Copilot, Claude Code, and Cursor) are included in the comparison. There's also an option to include only high-confidence matches in the local changes (editor/CLI) mode.

AI used

Compare AI-assisted PRs (GitHub Copilot, Claude Code, and Cursor) vs everything else. You can select which modes are included in the comparison. There's also an option to include only high-confidence matches in the local changes (editor/CLI) mode.

Frequently asked questions

Why is the Total PR count lower than the sum of the AI tool or mode categories?

A single pull request can be associated with multiple AI tools and modes. For example, a developer might use both Cursor and Claude Code on the same PR. In that case, the PR is counted once in the Cursor category and once in the Claude Code category.
