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.

   
   - This screen is similar to the [Provider Settings](#provider-settings) screen, and includes in-place documentation for each field.

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.

6. 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.

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

   

Manage Providers

• You can create unlimited provider configurations, and multiple configs can coexist for the same provider.
• Provider names must be unique.

Provider List

Open the VS Code Command Palette and search for Unify Chat Provider: Manage Providers.

• Add Provider: Add a new provider via Manual Configuration.
• Add From Well-Known Provider List: Add a new provider via One-Click Configuration.
• Import From Config: Import an existing provider config (or an array of provider configs). See Import and Export.
• Import From Other Applications: Import configs from other apps/extensions via One-Click Migration.
• Export All Providers: Export all provider configs. See Import and Export.

The UI also shows all existing providers. Click a provider item to enter the Model List screen.

The button group on the right of each provider item provides additional actions:

• Export: Export this provider config. See Import and Export.
• Duplicate: Clone this provider config to create a new one.
• Delete: Delete this provider config.

Provider Settings

• Models: This button only appears while adding or importing a config; click it to enter the Model List screen.

This screen shows all configuration fields for the provider. For field details, see Provider Parameters.

Manage Models

• Each provider can have unlimited model configurations.
• The same model ID can exist under different providers.
• Within a single provider config, you cannot have multiple identical model IDs directly, but you can create multiple configs by adding a #xxx suffix.
• For example, you can add both glm4.7 and glm4.7#thinking to quickly switch thinking on/off.
• The #xxx suffix is automatically removed when sending requests.
• Model names can be duplicated, but using distinct names is recommended to avoid confusion.

Model List

• Add Model: Go to Add Model Manually.
• Add From Well-Known Model List: Go to One-Click Add Models.
• Add From Official Model List: Fetch the latest official model list via API. See One-Click Add Models.
• Import From Config: Import an existing model config (or an array of model configs). See Import and Export.
• Auto-Fetch Official Models: Enable or disable Auto-Fetch Official Models.
• Provider Settings: Go to Provider Settings.
• Export: Export this provider config or the model array config. See Import and Export.
• Duplicate: Clone this provider config to create a new one.
• Delete: Delete this provider config.

Add Model Manually

This screen is similar to the Model Settings screen; you can read the in-place documentation to understand each field.

One-Click Add Models

This screen lists all models that can be added with one click. You can import multiple selected models at once.

See the Model Support Table for the full list of supported models.

Auto-Fetch Official Models

This feature periodically fetches the latest official model list from the provider’s API and automatically configures recommended parameters, greatly simplifying model setup.

Tip

A provider’s API may not return recommended parameters. In that case, recommended parameters are looked up from an internal database by model ID. See the Model Support Table for models that have built-in recommendations.

• Auto-fetched models show an internet icon before the model name.
• If an auto-fetched model ID conflicts with a manually configured one, only the manually configured model is shown.
• Auto-fetched models are refreshed periodically; you can also click (click to fetch) to refresh manually.
• Run the VS Code command Unify Chat Provider: Refresh All Provider's Official Models to trigger refresh for all providers.

Model Settings

• Export: Export this model config. See Import and Export.
• Duplicate: Clone this model config to create a new one.
• Delete: Delete this model config.

This screen shows all configuration fields for the model. For field details, see Model Parameters.

• Multiple provider configurations (array)
• Multiple model configurations (array)

Supported import/export formats:

• Base64-url encoded JSON config string (export uses this format only)
• Plain JSON config string
• A URL pointing to a Base64-url encoded or plain JSON config string

URI Support

Supports importing provider configs via VS Code URI.

Example:

vscode://SmallMain.vscode-unify-chat-provider/import-config?config=<input>

<input> supports the same formats as in Import and Export.

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.

Provider Advocacy

If you are a developer for an LLM provider, you can add a link like the following on your website so users can add your model to this extension with one click:

<a href="vscode://SmallMain.vscode-unify-chat-provider/import-config?config=eyJ0eXBlIjoi...">Add to Unify Chat Provider</a>

Cloud Sync Compatibility

Extension configs are stored in settings.json, so they work with VS Code Settings Sync.

However, sensitive information is stored in VS Code Secret Storage by default, which currently does not sync.

So after syncing to another device, you may be prompted to re-enter keys or re-authorize.

If you want to sync sync-safe sensitive data (e.g., API keys), enable storeApiKeyInSettings.

OAuth credentials are always kept in Secret Storage to avoid multi-device token refresh conflicts.

This can increase the risk of user data leakage, so evaluate the risk before enabling.

API Format Support Table

API	ID	Typical Endpoint	Notes
OpenAI Chat Completion API	openai-chat-completion	/v1/chat/completions	If the base URL doesn’t end with a version suffix, /v1 is appended automatically.
OpenAI Responses API	openai-responses	/v1/responses	If the base URL doesn’t end with a version suffix, /v1 is appended automatically.
Google AI Studio (Gemini API)	google-ai-studio	/v1beta/models:generateContent	Automatically detect the version number suffix.
Google Vertex AI	google-vertex-ai	/v1beta/models:generateContent	Provide different base URL based on authentication.
