Choose from a selection of models, each with its own particular strengths. You may have a favorite model that you like to use, or you might prefer to use a particular model for inquiring about a specific subject.
To view the available models per client, see GitHub Copilot中支持的 AI 模型.
注意
The models available to you depend on your Copilot plan and where you're using Copilot, such as GitHub.com or an IDE. Different models consume AI credits at different rates based on their token pricing. For details, see GitHub Copilot 的模型和定价.
Copilot allows you to change the model during a chat and have the alternative model used to generate responses to your prompts.
如果你是通过Copilot ChatCopilot Business或Copilot Enterprise订阅访问，则你的组织或企业必须允许成员切换到其他模型。 请参阅 管理组织中GitHub Copilot的策略和功能 或 管理企业中 GitHub Copilot 的策略和功能。
Changing the model used by Copilot Chat does not affect the model used for Copilot inline suggestions. See Changing the AI model for GitHub Copilot inline suggestions.

注意
- 如果使用 Copilot Extensions，它们可能会替代所选的模型。
- 模型的实验性预发布版本可能无法与所有筛选器正确交互，包括用于阻止匹配公共代码建议的设置（请参阅“以个人订阅者身份管理 GitHub Copilot 策略”）。
- 单击标题栏中的Copilot Chat聊天图标打开Visual Studio Code。
- At the bottom of the chat view, select the CURRENT-MODEL dropdown menu, then click the AI model of your choice.
注意
如果选择“ 自动”， Copilot auto model selection 将基于可用性选择最佳模型，并帮助降低速率限制。 请参阅“关于 Copilotauto model selection”。
Adding more models
You can expand the model options that are available to power Copilot Chat. You can add models from:
- A model provider—such as Anthropic, Gemini, OpenAI, and others.
- The AI Toolkit for Visual Studio Code.
注意
Using the AI Toolkit for VS Code is in 公开预览 and subject to change.
Prerequisites
- Depending on the provider or model you choose, you may need to supply an API key, or model ID, from the provider, or a GitHub personal access token (PAT).
- To add models from the AI Toolkit for Visual Studio Code, you must install the AI Toolkit extension.
- If you are on a Copilot Business or Copilot Enterprise plan and want to use third-party models in a supported IDE, the Bring Your Own Language Model Key in Select IDEs policy must be enabled. For more information, see 管理组织中GitHub Copilot的策略和功能 or 管理企业中 GitHub Copilot 的策略和功能.
Adding models
-
In the Copilot chat view, click the CURRENT-MODEL dropdown menu.
-
Click Manage Models.
A list of providers is displayed.
If you have installed the AI Toolkit, then additional providers, added via the AI Toolkit, are also listed.
-
Click the provider whose model(s) you want to add.
-
Depending on which provider you selected, you may be prompted to enter a GitHub PAT, an API key for the provider, or a model ID for a specific model.
Enter the required information, then press Enter.
A list of available models is displayed.
-
Select the model(s) you want to add, then click OK.
The models you selected are now available in the model picker in the chat view.
If you added a model from a provider via the AI Toolkit then the first time you use the model, you will be prompted to download it. You may also be prompted to authenticate with the provider.
提示
If you're already using chat with auto model selection, you'll need to start a new chat session to switch models. To start a new session, in the top right of the chat view, click new chat.
