GitHub Copilot code suggestions in your IDE

Copilot in Visual Studio Code provides two kinds of code suggestions:

Ghost text suggestions

Copilot offers coding suggestions as you type. You can also describe something you want to do using natural language within a comment, and Copilot will suggest the code to accomplish your goal.

Next edit suggestions (public preview)

Based on the edits you are making, Copilot will predict the location of the next edit you are likely to make and suggest a completion for it. Suggestions may span a single symbol, an entire line, or multiple lines, depending on the scope of the potential change. To enable next edit suggestions, see Configuring GitHub Copilot in your environment.

GitHub Copilot provides suggestions for numerous languages and a wide variety of frameworks, but works especially well for Python, JavaScript, TypeScript, Ruby, Go, C# and C++. GitHub Copilot can also assist in query generation for databases, generating suggestions for APIs and frameworks, and can help with infrastructure as code development.

Code suggestions that match public code

GitHub Copilot checks each suggestion for matches with publicly available code. Matches may be discarded or suggested with a code reference, based on the setting of the "Suggestions matching public code" policy for your account or organization. See GitHub Copilot code referencing.

About the AI model used for Copilot inline suggestions

Copilot inline suggestions use the GPT-4.1 Copilot model. The GPT-4.1 Copilot model was trained on a wide range of high quality public GitHub repositories, providing coverage of over 30 programming languages. See Programming languages included in the default model below.

Changing the model used for inline suggestions

You can switch the AI model that's used for Copilot inline suggestions if:

An alternative model is currently available

You are using the latest releases of VS Code with the latest version of the GitHub Copilot extension

Changing the model only affects Copilot ghost text suggestions. It does not affect Copilot next edit suggestions.

If you are on a Copilot Free plan, all completions count against your completions quota regardless of the model used. See Plans for GitHub Copilot.

The setting to enable or disable suggestions that match public code are applied irrespective of which model you choose. See Finding public code that matches GitHub Copilot suggestions.
