Copilot Chat improvements for pull requests

GitHub Copilot Chat now provides richer context and new capabilities when you're working with diffs and pull requests.

CleanShot.2026-04-21.at.10.46.05.mp4

You can access this functionality by asking a question about a pull request in github.com/copilot, or via the global Copilot navigation, which allows you to open chat over any GitHub surface.

Public-preview-enabled users can also click the Copilot button on a diff to ask a series of questions to better understand the changes or the related pull request.

New abilities

Three new abilities improve how Copilot Chat responds to pull request questions. These work in both on-page and immersive (github.com/copilot) chat:

• Pull request understanding: When a pull request is given as context, Copilot Chat now includes data like comments, file changes, commits, and reviews.
• Pull request review: Ask Copilot Chat to help review a pull request, and it'll provide a structured review.
• Pull request summary: Ask Copilot Chat to summarize a pull request, and it'll provide a concise overview of the changes.

We've updated the suggested prompts for chat (e.g., "Help review this pull request") to guide you through the relevant functionality.

How about instead of improving this, maybe re-add the opus models so we can actually use this new 'awesome' feature?

I went to pro+ yesterday, counted every single question I asked, it was 53(this contains the around 8 Copilot finished thinking Message interruptedCopilot was interrupted before it could finish this message. before Copilot died for a couple hours), this was april 22, when copilot was down for hours. When it came back I asked 2-3 questions got rate limited for the rest of the day. I was checking the usage today 1020 requests. I used Claude Opus 4.7 with a 7.5x token that would be around 134 questions. Why was I overbilled 81 question? or 90 if we take into account the ones copilot weren't responding. Anyone else experience this overbilling? Now I suspect the same happened before given how fast I went through the previous Pro premium requests with the 3x model. Claude Opus 4.6
