GitHub Copilot is an OpenAI-powered Visual Studio Code extension that can suggest lines of code or entire functions as you type.

Microsoft had a great thing going when it had GitHub Copilot all to itself in Visual Studio and Visual Studio Code thanks to its ownership of GitHub, but that's eroding.

If GitHub Copilot is not working or is not responding in Visual Studio or VS Code, it's most likely facing an authentication, network, or compatibility issue.
