メモ

Support to use your own provider (BYOK) in the GitHub Copilot アプリ is in パブリック プレビュー and subject to change.

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

メモ

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 Copilot での LLM プロバイダー API キーの使用 and Copilot での LLM プロバイダー API キーの使用.

Prerequisites

Add a model provider

  1. Open the GitHub Copilot アプリ.
  2. Open app settings, then click Model providers.
