OpenAI GPT-4.5 in GitHub Copilot now available in public preview

GitHub Copilot GPT-4.5

OpenAI’s latest model, GPT-4.5, is now available in GitHub Copilot Chat to Copilot Enterprise users. GPT-4.5 is a large language model designed with advanced capabilities in intuition, writing style, and broad knowledge. It performs effectively with creative prompts and provides reliable responses to obscure knowledge queries. GPT-4.5 will launch in Visual Studio Code and on github.com for Copilot Enterprise users with a limit of 10 requests every 12 hours per user. In the coming weeks, we’ll be scaling rate limits and extending support to Visual Studio and JetBrains.

GPT 4.5 in the VS Code Model Picker

As model releases have continued to accelerate, we’ve been thinking about how we can sustainably offer advanced AI models like GPT-4.5 to more GitHub users. This includes individual developers who want the most advanced capabilities from day one. Stay tuned for updates.

Enabling access

Copilot Enterprise administrators will need to enable access to GPT-4.5 via a new policy in Copilot settings. As an administrator, you can confirm availability by checking your individual Copilot settings and confirming the policy for GPT-4.5 is set to “enabled”. Once enabled, users will see GPT-4.5 in the Copilot Chat model selector in VS Code and on github.com.

Code review in GitHub Copilot is now in public preview

Copilot Code Review

No more wait: Copilot code review is here

Code review is one of the most critical parts of software development. Manual code reviews, while essential, 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 automatic fixes. This means you can start iterating on your code while you wait for a human review—helping you keep your code repositories more maintainable and focused on quality.

Today we’re excited to announce that all Copilot subscribers can now use Copilot code review, with a host of updates that we’ve made since its initial preview. To get started, sign up here.

What’s new

  • Review summary: Copilot gives you a detailed summary of the changes in a pull request—bridging the gap between automated feedback and human insight.
  • Smarter reviews: We’re leveraging the latest models to provide even more insightful and effective feedback, identifying potential issues you might otherwise miss.

Here’s Copilot code review in action, providing a summary of the pull request and some suggested improvements:

To request a code review from Copilot, you can set up automatic reviews in a repo through repository rules. Or, if you prefer, you can ask Copilot to review a pull request on demand.

You can also jump directly into the new Copilot Workspace experience from your pull request, to refine and validate Copilot’s suggestions. And don’t forget, you can always review your code in Visual Studio Code before you push it to GitHub, keeping your development process agile and efficient.

To learn more, check out the docs. We can’t wait for you to try out these improvements, and we’d love your feedback in this GitHub Community Discussion.

Deprecation of beta GitHub Copilot usage API endpoint

Beginning February 2025, the beta Copilot /usage endpoints will be deprecated.
No new data will be inserted for retrieval via the beta /usage endpoints. This endpoint will be accessible through February, but the 28 day retention policy will remain.

Who’s impacted?

Enterprise organizations with Copilot licenses not yet migrated from the /usage metrics APIs are impacted by this deprecation.

What’s changing and why?

The deprecation of the beta /usage endpoints is a part of GitHub’s effort to deliver more powerful and flexible data offerings for enterprises, organizations, and teams. The new endpoints provide:

  • Visibility into the adoption and consumption of Copilot across various stages of dev lifecycle (from code suggestions to PR reviews), from the team to the enterprise level
  • Expanded scope of metrics, with the addition of GitHub.com Copilot Chat and Copilot for Pull Requests
  • Consistent terminology with the user management API
  • Better visibility into unique users at various drilldowns

Next steps

Ensure your organization is no longer consuming the now deprecated /usage endpoints in any jobs, workflows, and analytics tools.
As an alternative to the beta Copilot /usage endpoints, check out the PowerBI template and the Copilot /metrics endpoints.

Copilot Autofix is available for more code scanning alerts

Copilot Autofix helps you fix code scanning alerts and avoid introducing new security vulnerabilities by using large language models to suggest potential fixes.

We recently expanded the range of CodeQL security alerts where Copilot can suggest an autofix, covering a group that accounts for 29% of all CodeQL alerts. This expansion led to an 8% overall increase in alerts with an available autofix and a 270% increase in autofixes for this specific group of improved alerts. With more autofix suggestions, you can resolve security issues identified by CodeQL more easily—either by applying Copilot’s suggested fix directly or using it as a starting point for your own edits.

We made these improvements by analyzing our usage data to understand the most common types of alerts where Copilot was not suggesting fixes and then made a targeted effort to improve autofix for these alerts. Read more about the testing process that GitHub uses to identify the quality of autofix suggestions.

We continuously evaluate the performance of CodeQL and Copilot Autofix, so look for more improvements in the future.

Announcing the General Availability of GitHub Copilot Extensions

Copilot Extensions GA

Your tools. Your workflows. All within Copilot Chat.

GitHub Copilot Extensions are now generally available for users across all Copilot license tiers. With Copilot Extensions, you can integrate and prompt your favorite tools directly in Copilot Chat using natural language wherever you develop, including Visual Studio Code, Visual Studio, JetBrains IDEs, and GitHub.com. Copilot Extensions on GitHub Mobile will be generally available in the coming weeks.

Copilot Extensions help you stay in your workflow, with context-aware assistance from your favorite tools right at your fingertips. Today’s marketplace is home to a wide range of extensions, from Perplexity to Stack Overflow, to Docker and Mermaid Chart. Developers can unlock productivity gains with extensions in minutes. For example, Arm’s extension streamlines cloud adoption and migration, enabling developers to build, test, and deploy software on Arm-based servers while seamlessly leveraging Arm’s efficient, scalable, and high-performance architecture.

Explore these extensions and more on the GitHub Marketplace to bring new contexts and capabilities into the chat. All you need is access to GitHub Copilot to get started. 🚀

Building GitHub Copilot Extensions

Our platform also empowers you to build your own public or private extension depending on your requirements. This flexibility allows you to develop extremely customized extensions for your enterprise or organization, or develop general applications that can serve thousands of developers. The comprehensive Copilot Extensions toolkit provides you with centralized code samples and tools to help you build high quality extensions.

Alongside General Availability, we’re introducing OpenID Connect (OIDC) support for builders. This replaces the X-Github-Token auth model with native third-party tokens, reducing API round trips, and improving security. Instead of verifying GitHub tokens on every request, integrators receive pre-exchanged tokens tailored to their system, enabling direct authentication and authorization. This lowers latency, simplifies identity mapping, and aligns with GitHub’s existing OIDC workflows for Actions.

Builders have several ways to develop customized extensions, including:

  • Copilot skillsets, a faster, lightweight implementation option
  • Context passing, a capability that helps extensions benefit from a user’s local editor context for more tailored responses

Ready to contribute to our growing ecosystem? Get started with our Copilot Extension builder docs.

👀 What’s next?

Our general availability is only the starting point for agentic capabilities. We’re continuing to reimagine AI assisted workflows, with recent releases like agent mode and explorations around Project Padawan. These innovations only scratch the surface of what is possible with GitHub and AI agents. Continue being a part of the conversation by providing feedback as you try out extensions. ⭐
