One-Click Configuration

See the Provider Support Table for providers supported by one-click configuration.

If your provider is not in the list, you can add it via Manual Configuration.

Steps:

1. Open the VS Code Command Palette and search for Unify Chat Provider: Add Provider From Well-Known Provider List.

2. Select the provider you want to add. 3. Follow the prompts to configure authentication (usually an API key, or it may require logging in via the browser), then you’ll be taken to the config import screen. - This screen lets you review and edit the config that will be imported. - For details, see the Provider Settings section.

1. Click Save to complete the import and start using the models in Copilot Chat.

Manual Configuration

This section uses DeepSeek as an example, adding the provider and two models.

DeepSeek supports One-Click Configuration. This section shows the manual setup for demonstration purposes.

0. Preparation: get the API information from the provider docs, at least the following: - API Format: The API format (e.g., OpenAI Chat Completions, Anthropic Messages). - API Base URL: The base URL of the API. - Authentication: Usually an API key; obtained from the user center or console after registration.

1. Open the VS Code Command Palette and search for Unify Chat Provider: Add Provider.

2. Fill in the provider name: Name. - The name must be unique and is shown in the model list. Here we use DeepSeek. - You can create multiple configs for the same provider with different names, e.g., DeepSeek-Person, DeepSeek-Team.

3. Choose the API format: API Format. - DeepSeek uses the OpenAI Chat Completion format, so select that. - To see all supported formats, refer to the API Format Support Table.

4. Set the base URL: API Base URL. - DeepSeek’s base URL is https://api.deepseek.com.

5. Configure authentication: Authentication. - DeepSeek uses API Key for authentication, so select API Key. - Enter the API key generated from the DeepSeek console.

1. Click Models to go to the model management screen.

7. Enable Auto-Fetch Official Models. - This example uses auto-fetch to reduce configuration steps; see Auto-Fetch Official Models for details. - For model fields and other ways to add models, see Manage Models.

1. Click Save to finish. You can now use the models in Copilot Chat.

Sync Built-in Parameters to All Configs

Run Unify Chat Provider: Sync Built-in Parameters to All Configs to sync local model parameters with the built-in model parameters.

This is typically used after a new version updates or optimizes built-in model parameters, allowing you to sync existing configs in one click.

Global Settings

• Most unifyChatProvider.* settings are application-scoped and shared across profiles on the same device.
• Commit message generation settings are window-scoped and can be configured per workspace.

Override Config Fields

You can add query parameters to override certain fields in the imported config.

Example:

vscode://SmallMain.vscode-unify-chat-provider/import-config?config=<input>&auth={"method":"api-key","apiKey":"my-api-key"}

The import will override the auth field before importing.
