Copilot code review now covers over 90% of the file types typically found in pull requests, so more of your code benefits from intelligent insights.
We’ve also improved the quality of suggestions. Copilot code review now surfaces higher-quality, more actionable feedback by better handling of low-confidence and suppressed results. These improvements are especially noticeable in C#, where Copilot now provides more accurate and relevant suggestions with improved version awareness.
In addition, Copilot has improved its ability to understand context. Instead of primarily looking at the file diff in the pull request, it now considers the entire file. This leads to more holistic and relevant review suggestions.
The GitHub Copilot for Xcode extension now allows you to ask questions about your entire codebase using the @workspace context. Additionally, we have added support for new models, including Claude 3.7 Sonnet and GPT 4.5, to enhance your chat conversations and introduce some UX improvements to boost your productivity.
What’s new ✨
@workspace context: By referencing @workspace in Copilot Chat, you can ask questions about your entire codebase. GitHub Copilot will analyze your project’s codebase and provide detailed answers, including references to relevant files and symbols. The @workspace context helps you find the code you’re looking for, understand how functionality is implemented, and much more.
New model options: Claude 3.7 Sonnet and GPT 4.5 are now available in the model selector of Copilot Chat. Learn more about the models available in our documentation.
UX improvements & bug fixes ⚡️
This update also includes a few other UX improvements and bug fixes:
Simplified Workflow: Open Copilot Chat with a single click from our Copilot for Xcode app, making it easier and faster to access. This helps streamline the development process and reduce time spent navigating various menus.
Bug fixes: Notifications for enabling background functionality to address crashes or non-responsive states.

Code review is one of the most critical parts of software development, but manual code reviews can be time-consuming. Copilot code review helps you offload basic reviews to a Copilot agent that finds bugs, potential performance problems, and even suggests fixes. This means you can start iterating on your code while waiting for a human review, helping you keep your code repositories more maintainable and focused on quality.
In just over a month since we launched the public preview, over 1 million developers have already used Copilot code review, and the response has been incredible.
Check it out in action, in both Visual Studio Code and GitHub:
To request a code review from Copilot, you can set up automatic reviews in a repo through repository rules. Or, you could ask Copilot to review a pull request on demand.
Copilot code review is available to all paid Copilot subscribers. Organizations and enterprises can enable it through the Copilot in github.com policy.
What’s next
We’re continuously improving Copilot code review. Today we’ve added support for C, C++, Kotlin, and Swift in public preview and we’ll add support for HTML and txt early next week.
Today, we’re introducing GitHub Copilot Pro+, a new individual tier for developers who want to take their coding experience to the next level.
Enjoy all the features you love from GitHub Copilot Pro along with exclusive access to the latest models (GPT-4.5 is available today), priority access to previews, and 1500 premium requests per month when they go live on May 5th. This is in addition to the unlimited requests for agent mode, context-driven chat, and code completions that all paid plans have when using our base model. Editor’s note (April 23, 2025): Rate limiting is in place to accommodate for high demand. Learn more about current models and usage.
