## Installation

- Requires VS Code 1.115.0 or later.
- Search for [Unify Chat Provider](https://marketplace.visualstudio.com/items?itemName=SmallMain.vscode-unify-chat-provider) in the VS Code Extension Marketplace and install it.
- Download the latest `.vsix` file from [GitHub Releases](https://github.com/smallmain/vscode-unify-chat-provider/releases), then install it in VS Code via `Install from VSIX...` or by dragging it into the Extensions view.

## Quick Start

If the provider you want to add is in the [Provider Support Table](#provider-support-table), use [One-Click Configuration](#one-click-configuration).

Otherwise, you can also [manually configure](#manual-configuration) any provider and model.

You might also be looking for:

- [One-Click Migration](#one-click-migration): Migrate from other apps or extensions.
- [Manage Providers](#manage-providers): Unified management for all providers and models.
- [Import and Export](#import-and-export): Back up or export configurations to share with others.

> ⚠️ **Avoid VS Code background tasks consuming Copilot quota**
>
> VS Code currently uses utility models for some background tasks by default. If you use a free Copilot account, this may consume your Copilot quota.
>
> You need to set these to other models in `settings.json` yourself to avoid consuming Copilot quota, or use the quick settings interface provided by this extension. See [Quick Set VS Code Default Model](#quick-set-vs-code-default-model) for details.

> ⚠️ **Allow the extension to enable Proposed APIs**
>
> This extension uses some experimental VS Code extension APIs. After installation, you may be prompted to enable these APIs, which requires administrator privileges. Allow them for the best experience.
>
> The extension will still work without them, but with the following limitations:
> - Some models will be less effective.
> - Commit message generation will be significantly less effective.
> - The native commit message generation button will be unavailable.
> - Code completion will be unavailable.
> - Preset templates will be unavailable.

## Basic Operations

The UI is integrated into the VS Code Command Palette for a more native experience. Here’s the basic workflow:

1. Open the Command Palette:
   - From the menu: `View` -> `Command Palette...`
   - Or with the shortcut: `Ctrl+Shift+P` (Windows/Linux) or `Cmd+Shift+P` (Mac)
2. Search commands:
   - Type `Unify Chat Provider:` or `ucp:` to find all commands.
3. Run a command:
   - Select a command with mouse or arrow keys, then press Enter.

## One-Click Configuration

See the [Provider Support Table](#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](#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](#provider-settings) section.

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

## Code Completion

Open the VS Code Command Palette and search for `Unify Chat Provider: Code Completion Settings`.

Code completion is enabled by default, but it takes effect only after you add at least one valid completion algorithm.

### Conflict Notice

Once this extension's code completion becomes active, it automatically disables VS Code's built-in code completion.

To allow both to coexist, which is not recommended, change `Code Completion Settings -> Completion Strategy Settings -> Disable VS Code Built-in Completion`.

When multiple extensions provide code completion, VS Code returns results only from the one that responds fastest. We therefore recommend enabling code completion in only one extension.

### Supported Algorithms

| Name              | ID                  | Description                                                                                      |
| ----------------- | ------------------- | ------------------------------------------------------------------------------------------------ |
| Simple            | `simple`            | The simplest FIM implementation; sends only the current document's prefix and suffix and works with any model. |
| Copilot (Replica) | `copilot-replica`   | A complete replica of VS Code Copilot's core FIM/NES implementation that works with any model.  |
| Zed               | `zed`               | A complete replica of Zed Edit Prediction that supports Zeta models only.                       |
| Inception         | `inception`         | Implements the documented best practices and supports Mercury Edit 2 only.                      |
| Mistral           | `mistral`           | Implements the documented best practices and supports Codestral only.                           |

We recommend the [Zed](#zed) and [Inception](#inception) algorithms for better results.

### Simple

This algorithm supports any model. A model designed specifically for FIM code completion, such as Qwen Coder, is recommended.

Models such as DeepSeek V4 may support FIM but perform poorly in practice, so they are not recommended.

Steps:

1. First add a model configuration, then adjust its completion capabilities based on whether the model supports FIM:
   - Supports FIM: set `completion.template` to `fim`.
   - Supports chat only: set `completion.template` to `fim` and `completion.transport` to `compatible`.
2. Add a Simple algorithm through `Code Completion Settings -> Add From Current Provider List -> Simple`, then select the model to use.
3. Click `Save`.

### Zed

This algorithm provides the same code completion experience as the Zed editor.

Zed uses its own Zeta model family. We recommend adding it in one of two ways:

1. Add the `Zed` provider through [One-Click Configuration](#one-click-configuration) and use your Zed account quota.
2. Deploy a Zeta model locally and add it.
3. Add a Zed algorithm through `Code Completion Settings -> Add From Current Provider List -> Zed`, then select the model that was just added.
4. Click `Save`.

### Inception

1. Add the `Inception` provider through [One-Click Configuration](#one-click-configuration).
2. Add an Inception algorithm through `Code Completion Settings -> Add From Current Provider List -> Inception`, then select the `Mercury Edit 2` model.
3. Click `Save`.

### Mistral

1. Add the `Mistral` provider through [One-Click Configuration](#one-click-configuration).
2. Add a Mistral algorithm through `Code Completion Settings -> Add From Current Provider List -> Mistral`, then select the `Codestral` model.
3. Click `Save`.

## Manual Configuration

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

> DeepSeek supports [One-Click Configuration](#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`.

<div align="center">
   <img src="assets/screenshot-6.png" width="600" />
   </div>
   - 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](#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](#auto-fetch-official-models) for details.
   - For model fields and other ways to add models, see [Manage Models](#manage-models).

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

## One-Click Migration

See the [Application Migration Support Table](#application-migration-support-table) to learn which apps and extensions are supported.

> If your app/extension is not in the list, you can configure it via [One-Click Configuration](#one-click-configuration) or [Manual Configuration](#manual-configuration).

**Steps:**

1. Open the VS Code Command Palette and search for `Unify Chat Provider: Import Config From Other Applications`.

- The UI lists all supported apps/extensions and the detected config file paths.
  - Use the button group on the far right of each item for additional actions:
    1. `Custom Path`: Import from a custom config file path.
    2. `Import From Config Content`: Paste the config content directly.

2. Choose the app/extension you want to import, 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](#provider-settings) section.

3. Click `Save` to complete the import and start using the imported 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](#manual-configuration).
- `Add From Well-Known Provider List`: Add a new provider via [One-Click Configuration](#one-click-configuration).
- `Import From Config`: Import an existing provider config (or an array of provider configs). See [Import and Export](#import-and-export).
- `Import From Other Applications`: Import configs from other apps/extensions via [One-Click Migration](#one-click-migration).
- `Export All Providers`: Export all provider configs. See [Import and Export](#import-and-export).

The UI also shows all existing providers. Click a provider item to enter the [Model List](#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](#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](#model-list) screen.

This screen shows all configuration fields for the provider. For field details, see [Provider Parameters](#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-model-manually).
- `Add From Well-Known Model List`: Go to [One-Click Add Models](#one-click-add-models).
- `Add From Official Model List`: Fetch the latest official model list via API. See [One-Click Add Models](#one-click-add-models).
- `Import From Config`: Import an existing model config (or an array of model configs). See [Import and Export](#import-and-export).
- `Auto-Fetch Official Models`: Enable or disable [Auto-Fetch Official Models](#auto-fetch-official-models).
- `Provider Settings`: Go to [Provider Settings](#provider-settings).
- `Export`: Export this provider config or the model array config. See [Import and Export](#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](#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](#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](#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](#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](#model-parameters).

### 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.

## Commit Message Generation

You can generate commit messages via the following commands:

- `Unify Chat Provider: Generate Commit Message`
- `Unify Chat Provider: Generate Commit Message(All Changes)`
- `Unify Chat Provider: Generate Commit Message(Staged Changes)`
- `Unify Chat Provider: Generate Commit Message(Unstaged Changes)`

You can also click the sparkle button on the right side of the commit message input box in the Source Control view to generate a commit message (on first use, you need to click the dropdown arrow next to the button and select `Unify Chat Provider: Generate Commit Message` from the dropdown menu).

## Balance Monitoring

Use this feature to monitor provider balances in `Provider Settings`.

- Run the VS Code command `Unify Chat Provider: Provider Balance Monitoring` to open the balance monitoring panel.
- Configure it from the `Balance Monitor` field.
- Built-in methods:
  - `Moonshot AI Balance`: no extra config required; uses provider `baseUrl` and API key.
  - `Kimi Code Usage`: no extra config required; uses provider `baseUrl` and API key.
  - `New API Balance`: always shows API key balance; user balance is optional and requires `userId` + `systemToken` (sensitive data).
  - `DeepSeek Balance`: no extra config required; uses provider `baseUrl` and API key.
  - `OpenRouter Balance`: no extra config required; uses provider `baseUrl` and API key.
  - `SiliconFlow Balance`: no extra config required; uses provider `baseUrl` and API key.
  - `AIHubMix Balance`: no extra balance config required; uses provider `baseUrl`, API key, and optional `APP-Code` from provider `extraHeaders`.
  - `Claude Relay Service Balance`: no extra config required; uses provider `baseUrl` and API key.
  - `Antigravity Usage`: no extra config required; uses the provider OAuth credential and project settings.
  - `Gemini CLI Usage`: no extra config required; uses the provider OAuth credential and optional project settings.
  - `Codex Usage`: no extra config required; uses provider credential (API key or Codex auth token).
- Run the VS Code command `Unify Chat Provider: Refresh All Providers' Balance Information` to force refresh balances for all configured providers.

## Adjust Parameters

### Global Settings

### Proxy Configuration

Proxy settings can be configured globally through `unifyChatProvider.networkSettings.proxy` or per provider through `unifyChatProvider.endpoints[].proxy`. The effective order is:

1. Provider `proxy`
2. Global `networkSettings.proxy`
3. VS Code HTTP proxy settings

`proxy.type` supports:

- `vscode` (default): Use VS Code `http.proxy`, `http.proxyAuthorization`, `http.proxyStrictSSL`, and `http.noProxy`.
- `direct`: Connect directly and bypass VS Code/global proxy settings.
- `custom`: Use `proxy.url`; optional fields are `authorization`, `strictSSL`, and `noProxy`.

Supported custom proxy URL protocols are `http`, `https`, `socks`, `socks4`, `socks4a`, `socks5`, and `socks5h`. Proxy settings apply to provider HTTP requests, including chat requests, balance refreshes, and official model fetching.

Example global proxy:

```json
{
  "unifyChatProvider.networkSettings": {
    "proxy": {
      "type": "custom",
      "url": "http://127.0.0.1:7890",
      "noProxy": ["localhost", "127.0.0.1", ".example.com"]
    }
  }
}
```

Example provider override:

```json
{
  "unifyChatProvider.endpoints": [
    {
      "type": "openai-chat-completion",
      "name": "OpenAI Direct",
      "baseUrl": "https://api.openai.com",
      "proxy": {
        "type": "direct"
      },
      "models": ["gpt-5"]
    }
  ]
}
```

Supports `fim`, `codegemma`, `copilot-replica-nes`, `zeta1`, `zeta2`, `zeta2.1`, `zeta3-internal`, `mercury-edit-2`, and `codestral`; an empty array explicitly disables completion for this model. |
| Preset Templates           | `presetTemplates`                    | Array of preset templates in the VS Code model submenu. Templates are applied in declaration order, and later templates override same-named fields from earlier templates.                                     |

#### Service Tier Notes

- Leaving `serviceTier` empty means this extension omits the service tier / speed fields and keeps the provider default behavior.
- Mapping for the OpenAI API:
  - `auto` -> `auto`
  - `standard` -> `default`
  - `flex` -> `flex`
  - `scale` -> `scale`
  - `priority` -> `priority`
- Mapping for Anthropic Messages API:
  - `auto` -> `auto`
  - `standard` / `flex` / `scale` -> `standard_only`
  - `priority` -> `speed: "fast"` with `fast-mode-2026-02-01`

#### Preset Template Notes

You can configure multiple preset templates for a single model. Each template corresponds to one enum option group displayed in the VS Code model selection submenu.

Preset overrides for `thinking` are shallow-merged by child field, allowing independent reasoning controls to compose. Overrides for other top-level fields continue to replace the complete field value. The GPT-5.6 Sol, Terra, and Luna built-ins use the IDs `gpt-5.6-sol`, `gpt-5.6-terra`, and `gpt-5.6-luna`; each has a 1,050,000-token context window, 128,000-token output limit, OpenAI tokenization, tool and image support, and the apply-patch edit hint. The `gpt-5.6` alias resolves to Sol. These models expose `reasoningEffort` (`max`, `xhigh`, `high`, `medium`, `low`, `none`), `reasoningMode` (`standard`, `pro`), and `reasoningContext` (`auto`, `current_turn`, `all_turns`) without provider-default options. Their defaults are `xhigh`, `standard`, and `auto`.

You can define custom preset templates to switch model parameters quickly. For example:

```json
{
  "presetTemplates": [
    {
      "name": "Reasoning Effort",
      "id": "reasoningEffort",
      "presets": [
        {
          "name": "High",
          "description": "Suitable for tasks involving planning, coding, synthesis, or more difficult reasoning.",
          "id": "high",
          "config": {
            "thinking": {
              "type": "enabled",
              "effort": "high"
            },
            "temperature": 0.7
          }
        },
        {
          "name": "Low",
          "description": "A small amount of extra thinking can improve reliability with almost no added latency.",
          "id": "low",
          "config": {
            "thinking": {
              "type": "enabled",
              "effort": "low"
            },
            "temperature": 0.4
          }
        },
        {
          "name": "Default",
          "description": "Use the model's current configuration.",
          "id": "default",
          "config": {}
        }
      ],
      "default": "default"
    }
  ]
}
```

- `config` overrides fields in the model configuration. In the example above, `high` and `low` override `thinking` and `temperature`, while `default` overrides nothing and uses the model's current configuration.
- If multiple templates override the same field, they are applied in declaration order, and later templates override earlier fields with the same name.

| Cursor Prediction Model          | `options.cursorPredictionModel`         | Optional. Used only to predict the next cursor position for NES; reuses the current NES or unified model when unset. If this model is unavailable, only cursor prediction is disabled and the main NES request is unaffected.                              |
| NES Prompt Strategy              | `options.strategy`                      | Default in independent-model mode: `copilotNesXtab`. Options: `copilotNesXtab`, `xtab275`, `xtabUnifiedModel`, `xtabAggressiveness`, `xtab275Aggressiveness`, `xtab275AggressivenessHighLow`, `xtab275EditIntent`, `xtab275EditIntentShort`; match this to the model's prompt and response protocol. |
| Eagerness                        | `options.eagerness`                     | NES adaptive request strategy: `auto` / `low` / `medium` / `high`. Default: `auto`. Changing this field does not rebuild the stateful Copilot runtime.                                                                                                    |
| Completion Languages             | `options.enabledLanguages`              | Advanced. Map of language IDs to booleans, with `*` as a fallback, controlling automatic FIM. In unified-model mode, this works with `inlineEditsEnabledLanguages` to determine the completion channel. Enabled by default except for `plaintext`, `markdown`, and `scminput`; manually triggered independent FIM is not restricted by this setting. |
| Inline Edit Languages            | `options.inlineEditsEnabledLanguages`   | Advanced. Map of language IDs to booleans, with `*` as a fallback, controlling NES inline edits. Enabled by default except for `plaintext`, `markdown`, and `scminput`.                                                                                   |
| Respect Selected Completion Info | `options.respectSelectedCompletionInfo` | Advanced. Controls whether FIM treats the selected completion in the suggestion widget as a pending edit. When unset, this is determined automatically from the VS Code version and `editor.quickSuggestions` state.                                    |
| Include Inline Completions       | `options.includeInlineCompletions`      | Advanced. Whether NES may return inline completions in the current document. Default: `true`.                                                                                                                                                            |
| Include Inline Edits             | `options.includeInlineEdits`            | Advanced. Whether NES may return inline or cross-file edits. Default: `true`. When NES is enabled, this and `includeInlineCompletions` cannot both be `false`.                                                                                            |

### Completion Scheduling Strategy Parameters

| Name                               | ID                               | Description                                                                                                                                                                                                                 |
| ---------------------------------- | -------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Scheduling Mode                    | `mode`                           | `all` (default): immediately requests all providers concurrently; `main-first`: prioritizes the main provider.                                                                                                              |
| Disable VS Code Built-in Completion | `disableVSCodeBuiltinCompletion` | Default: `true`. Blocks VS Code's code completion; set to `false` to allow both to coexist.                                                                                                                                  |
| Disabled File Globs                | `disabledGlobs`                  | Additional file globs for which completion requests are not sent. Always merged with `**/.env*`, `**/*.pem`, `**/*.key`, `**/*.cert`, `**/*.crt`, `**/.dev.vars`, and `**/secrets.yml`; the built-in rules cannot be removed by setting an empty array. |
| Main Provider                      | `mainProvider`                   | Required in `main-first` mode; value is a `providers[].id`. If the reference does not exist, the runtime falls back to the default strategy and shows a throttled configuration warning.                                    |
| Main Provider Wait Time            | `mainFirstTimeoutMs`             | Non-negative milliseconds. Default: `500`. If the main provider still has no usable result, reaching this time starts or releases the other providers; it is not a cancellation timeout for the main request.                |
| Start Other Providers in Parallel  | `parallelRequestOthers`          | Used only by `main-first`. Default: `false`. When `false`, other providers start after the main provider fails, returns no result, or times out. When `true`, all start together, but other results enter the stopping condition only after the main provider finishes or its wait time expires. |
| Stopping Condition                 | `stopWhen`                       | Object controlling when to stop waiting and merge the currently available results.                                                                                                                                          |
| Stopping Condition Type            | `stopWhen.type`                  | `firstUsable` (default) / `deadline` / `enoughResults` / `allSettled`.                                                                                                                                                       |
| First Result Grace Period          | `stopWhen.graceMs`               | Non-negative milliseconds, used only by `firstUsable`. Time to keep collecting after the first usable result. Default: `0`.                                                                                                 |
| Deadline                           | `stopWhen.timeoutMs`             | Non-negative milliseconds; required by `deadline`. Returns available results when reached.                                                                                                                                  |
| Minimum Result Count               | `stopWhen.minItems`              | Positive integer; required by `enoughResults`. Counts completion items after merging and deduplication.                                                                                                                      |
| Enough Results Grace Period        | `stopWhen.graceMs`               | Non-negative milliseconds, used only by `enoughResults`. Time to keep collecting after reaching `minItems`. Default: `0`.                                                                                                   |

In `main-first` mode, a usable result from the main provider during the priority phase is returned immediately. Only after the main provider produces no usable result and the fallback phase begins are other providers merged according to `stopWhen`. The stopping conditions behave as follows:

- `firstUsable`: after the first usable result, waits up to `graceMs`, then returns and cancels running requests; returns earlier if every request finishes first.
- `deadline`: returns available results and cancels running requests when `timeoutMs` is reached; returns earlier if every request finishes first.
- `enoughResults`: after the deduplicated completion items reach `minItems`, waits `graceMs`, then returns and cancels running requests; if every request finishes first, returns the results available at that time.
- `allSettled`: waits until every scheduled request succeeds, fails, or returns no result.

Results from multiple providers are merged in actual completion order and deduplicated by target URI, inserted text, and replacement range, keeping the first occurrence. An error from one provider does not prevent other providers from returning results.

## Import and Export

Supported import/export payloads:

- Single provider configuration
- Single model configuration
- 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](#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.

Session-based authentication settings include a non-secret binding ID in `settings.json`, while OAuth tokens, client secrets, account/project context, and Zed organization/privacy state are stored in a versioned envelope in VS Code Secret Storage. Secret Storage does not sync.

Each device therefore authorizes and refreshes its own session. Syncing, renaming, or changing the account on one device cannot replace another device's token or account context. A newly synced device will ask you to authorize locally.

If you want to sync suitable sensitive data such as API keys, enable [`storeApiKeyInSettings`](vscode://settings/unifyChatProvider.storeApiKeyInSettings).

OAuth and Zed credentials are always kept in Secret Storage to avoid multi-device refresh and account-context conflicts. Explicitly exporting and importing sensitive data can still place the same upstream credential on multiple devices.

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

## Quick Set VS Code Default Model

You can open the quick settings interface with the VS Code command `Unify Chat Provider: Change VS Code Default Model`.

The following settings can be changed quickly:

- ★ `chat.utilityModel`
- ★ `chat.utilitySmallModel`
- ★ `chat.exploreAgent.defaultModel`
- ★ `github.copilot.chat.exploreAgent.model`
- `inlineChat.defaultModel`
- `chat.planAgent.defaultModel`
- `github.copilot.chat.askAgent.model`
- `github.copilot.chat.implementAgent.model`

Items marked with `★` mean:

- By default, VS Code uses Copilot built-in models for these settings. These models do not consume premium quota on paid plans, but may consume free quota on free plans.
- It is recommended to set them to fast, inexpensive models.

You can select the `Change All Built-in Utility Models` button to update all `★` items at once.
