GitHub Copilot

We’re launching ReviewBench, a benchmark for code review agents built on representative GitHub pull requests, multi-source ground truth, calibrated evaluation, and production-aligned metrics.

What is a developer to do when they need something more tangible than a chat box? Enter canvases.

How we rebuilt the diff surface in the GitHub Copilot app to open a million-line pull request with hundreds of inline review comments.

A rewrite this size wasn’t affordable before agents. Here’s what porting the Copilot agent runtime to 800,000 lines of production Rust actually took.

If you can write down how you do your work, you can automate it. Here’s what I did to support GitHub’s APAC marketing team.

In controlled offline evaluations, HydraFusion’s selective coding workflows matched or exceeded the evaluated Opus 5 baseline while reducing estimated workflow cost. Now available as a research preview in GitHub Copilot.

Why shorter outputs can cost more, and how GitHub Copilot reduces wasted work across the complete coding task.

Chat is great for intent, but agent work gets lost in the scroll. Here is how I use canvases with my agentic workflows—and why your workflow also deserves a canvas.

See how four GitHub agent apps can help you scope, secure, roll out, and ship a feature across the SDLC–all without leaving GitHub.
