Bring your own key (BYOK) allows you to use Copilot with models of your choice, such as models that are running on your local machine or hosted by an external provider.
There are two separate mechanisms for providing your own LLM keys to Copilot. One allows users to configure their own models locally, and the other allows enterprise and organization owners to provide custom models for all users.
Local BYOK
Various Copilot clients allow users to configure custom LLM keys locally.
These keys are only handled client-side: they are stored locally and the associated models aren't available to other users. This mechanism removes dependency on GitHub's Copilot API, making it suitable for air-gapped environments or users without Copilot subscriptions.
Local BYOK is available in the following clients.
| Client | More information |
|---|---|
| VS Code | Add a model from a built in provider in the VS Code documentation |
| JetBrains | Bring your own key (BYOK) support for JetBrains IDEs and Xcode on the GitHub Blog |
| Xcode | Bring your own key (BYOK) support for JetBrains IDEs and Xcode on the GitHub Blog |
| Copilot 命令行界面（CLI） | 在 GitHub Copilot CLI 中使用自己的 LLM 模型 |
| GitHub Copilot 应用 | 在 GitHub Copilot 应用中使用自己的 LLM 模型 |
| Copilot SDK | BYOK （自带密钥） |
For users on a Copilot业务 or Copilot Enterprise plan, the ability to use local BYOK in IDEs can be disabled by an enterprise or organization policy.
Enterprise BYOK
注意
将自有 API 密钥用于 GitHub Copilot 的功能处于 公开预览 阶段，可能会有所变动。
Enterprise owners can add keys for custom models in their enterprise settings. They can also allow organization owners to do the same in their organization settings, by enabling the Enable custom models policy.
Custom models are available in 副驾驶聊天、 Copilot 命令行界面（CLI）和 VS Code, and apply to users on the enterprise's Copilot业务 or Copilot Enterprise plan. Users can select them in the same way they would select a GitHub-hosted model.
Enterprise BYOK is handled server-side and affects the models served to users by the Copilot API. Users must have a Copilot license and internet access to use the custom models.
