Universal Chat Provider

The VS Code extension that brings your Claude, ChatGPT / Codex, Antigravity, and more subscriptions into GitHub Copilot Chat
_{No API key — just OAuth.
…and use them to write your Git commit messages, too.}

Features

🚀 Ready in minutes — install, sign in, and start chatting.
🔀 Native model picker — choose your models directly in Copilot Chat.
🧠 Reasoning built in — pick the thinking effort and follow reasoning live.
📊 Quota at a glance — see remaining usage and redeem available Codex resets with confirmation.
✨ More than chat — generate commit messages, titles, and summaries.
🎙️ Dictation — speak into the chat input via Codex or Gemini (unofficial endpoints).
👥 Account load balancing — add multiple accounts for the same provider; CLIProxyAPI distributes requests round-robin across available accounts and skips those in cooldown.

[!WARNING] Use entirely at your own risk and discretion. This extension routes chat through your personal AI subscription accounts over OAuth. Accessing subscriptions outside their official apps may violate provider terms and could result in rate limiting or account suspension.

Demo

Universal Chat Provider showcase: connect subscription accounts, choose chat models and reasoning effort, inspect quota, configure a utility model, and generate a Git commit message

Quick start

Requires VS Code 1.131+ and the GitHub Copilot Chat extension.

Install — get Universal Chat Provider from the VS Code Marketplace. Prefer to build it yourself? See Development.
Add an account — accept the Add Account prompt (or run Universal Chat Provider: Add Account), pick a provider, and complete OAuth in your browser. Models refresh automatically.
Chat — open Copilot Chat and select a model under Universal Chat Provider.

Manage everything from the status bar item or the Universal Chat Provider: Manage Provider command — inspect quota, redeem OpenAI-provided Codex reset credits, list/remove accounts, restart, update, or reset the managed server.

Commit messages, titles, and summaries

Let your models handle Copilot's light background tasks and Explore searches. Run Universal Chat Provider: Set Utility Model (or use the status bar menu), pick a model (and thinking effort), done. A small, fast, inexpensive model is usually the best fit. Clear it to undo.

How it works

The command points Copilot's chat.utilityModel, chat.utilitySmallModel, and chat.exploreAgent.defaultModel settings at your selected model, so commit messages, chat titles, summaries, and Explore searches run through your accounts. It also sets chat.byokUtilityModelDefault to mainAgent, so remaining utility flows fall back to your selected chat model instead of Copilot's. When the model supports thinking levels, the command also asks for the utility Thinking Effort; commit messages use chat.utilitySmallModel plus that effort. No Copilot subscription required.

How it works

The extension runs CLIProxyAPI locally and registers its models with VS Code. Your subscriptions then appear directly in the Copilot Chat model picker.

Your subscriptions run through a local CLIProxyAPI proxy over OAuth and appear in VS Code Copilot Chat as models and as the utility model.

Key	Description	Type	Default
▿ Connection
`universalChatProvider.server.mode`	How to run CLIProxyAPI.	`string`	`"managed"`
`universalChatProvider.baseUrl`	URL of your CLIProxyAPI server. External mode only.	`string`	`"http://127.0.0.1:8317"`

`universalChatProvider.server.updatePolicy`	How the managed server is updated.	`string`	`"automatic"`
`universalChatProvider.server.version`	CLIProxyAPI version for Manual updates: latest or an exact version (8.0.3 or newer).	`string`	`"latest"`
`universalChatProvider.server.extraConfig`	Extra YAML config for the managed server, such as proxy, retries, and account selection. Changing connection, credential, or provider settings can break the extension.	`string`	`"# requests:\n# proxy-url: http://127.0.0.1:7890\n# routing:\n# strategy: fill-first\n# retry:\n# request-retry: 3"`

`universalChatProvider.quotaWarningThreshold`	Warn when remaining quota drops below this percentage.	`number`	`10`
▿ Models
`universalChatProvider.models.showLatestOnly`	Hide older versions of a model when a newer one is available, e.g. Claude Opus 4.8 once Opus 5.5 is out.	`boolean`	`false`
▿ Dictation
`universalChatProvider.dictation.engine`	Speech-to-text via unofficial endpoints; may break. Empty is off. Codex models (`gpt-transcribe`, `gpt-live-transcribe`) are the most accurate and fastest; Gemini models such as `gemini-3-flash` work too but are slower. $(mic) Select Engine…	`string`	`""`

Extra managed configuration

Set universalChatProvider.server.extraConfig to a CLIProxyAPI v8 YAML mapping in the multiline settings field. For example:

routing:
  strategy: fill-first
  retry:
    request-retry: 5

Mappings merge recursively; other values replace generated values, and invalid YAML is rejected before a requested restart stops the server.

Managed-server updates

Updates download automatically by default and restart the managed server as soon as no requests are active. Change universalChatProvider.server.updatePolicy to suggestUpdates or manual if you'd rather review or pin them yourself. Manual mode uses the configured version, which defaults to latest; enter an exact version (8.0.3 or newer) to pin it. An installed release older than 8.0.3 is replaced with a supported one regardless of the update policy.

Bring your own CLIProxyAPI server

Prefer to run CLIProxyAPI yourself, such as on a remote or shared machine?

Set universalChatProvider.server.mode to external.
Start CLIProxyAPI and complete the provider login there.
Use the Import API Key notification action when a local config is found, or run Configure Connection to enter the URL and key manually.

The server must run CLIProxyAPI 8.0.3 or newer. Adding or removing an OpenAI-compatible endpoint through the extension saves the server's config.yaml in the v8 layout; CLIProxyAPI keeps unrecognized sections as comments.

The API key is stored in VS Code SecretStorage. In external mode, the extension never starts or stops the server. To use Add Account and Manage Accounts, enter your server's existing management key, not its bcrypt hash, in universalChatProvider.server.managementKey. Managed mode generates and stores its own key automatically and ignores this setting.
