Note

Support to use your own provider (BYOK) in the GitHub Copilot app is in public preview and subject to change.

You can configure the GitHub Copilot app to use your own LLM provider, also called BYOK (Bring Your Own Key), instead of GitHub-hosted models.

Note

This article is for users who want to configure their own LLM provider API key on their local machine. To set up custom models for users in an organization or enterprise, see Using your LLM provider API keys with Copilot and Using your LLM provider API keys with Copilot.
