Claude Sonnet 4 in GitHub Copilot: A Game Changer for Code Auditing

In recent weeks, I've had the opportunity to test Claude Sonnet 4 in GitHub Copilot, and the experience is impressive. This model from Anthropic, recently integrated into Copilot, offers significantly improved code auditing capabilities.

What is Claude Sonnet 4?

Claude Sonnet 4 is an AI model developed by Anthropic, designed to understand and generate code with increased precision. It is now available in GitHub Copilot, accessible through Pro and Enterprise plans.

Enhancements for Code Auditing

One of the most notable features is Claude Sonnet 4's ability to deeply analyze source code, detecting potential vulnerabilities and suggesting improvements. For instance, when reviewing a Python script, the model identified an insecure use of eval() and proposed a safer alternative, thereby reducing the risk of code injection attacks.

⚠Current Limitations

While promising, the integration of Claude Sonnet 4 in VS Code is not yet flawless. Some users report that the model is not always available for inline completions or direct editing within the editor, although it is accessible via Copilot Chat in the browser.

How to Use It?

To enable Claude Sonnet 4 in GitHub Copilot, go to Copilot settings on GitHub, then to the 'Models' section. Ensure that Claude Sonnet 4 is activated. Then, in VS Code, open Copilot Chat and select this model from the model picker.
