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

universalChatProvider.server.managementKey
External mode only. Enter your server's existing management key, not its bcrypt hash. Managed mode generates and stores its own key automatically and ignores this setting.

universalChatProvider.server.proxyUrl
Optional upstream proxy URL for the managed CLIProxyAPI server. Changes prompt before restarting.
string

universalChatProvider.server.extraConfig
Extra YAML merged into the managed CLIProxyAPI config. Mappings merge recursively; arrays and other values replace generated values. All keys can be overridden, including host, port, credentials, and providers, which can break extension connectivity or account management. Stored as plain text, not in secret storage. Changes prompt before restarting.

Session identity
Session handling targets CLIProxyAPI v7.3.3 or newer. The extension sends a model-scoped prompt_cache_key derived from Copilot's conversation ID, with an opening-message fingerprint fallback. It does not also send X-Session-ID to the proxy.
Endpoints added through the extension receive these CLIProxyAPI header defaults, matched by exact hostname:
Hostname
Upstream header
Value
opencode.ai
x-opencode-session
$CPA-SESSION-ID
openrouter.ai
x-session-id
$CPA-SESSION-ID
The proxy resolves $CPA-SESSION-ID from its session identity. Existing managed endpoints receive missing defaults when their config is regenerated. Existing headers take precedence regardless of casing, including empty values; server.extraConfig remains the final override. Other endpoints are unchanged.
Existing external-server endpoints are not rewritten. Add the relevant mapping under that provider's headers in your CLIProxyAPI configuration, or re-add the endpoint through the extension. Migrate custom mappings that copy $X-Session-ID to $CPA-SESSION-ID, since the extension no longer supplies the former header. Update older pinned or external proxies before relying on this behavior. A one-time session/cache reset may occur when changing identity sources.
Extra managed configuration
Set universalChatProvider.server.extraConfig to a YAML mapping in the multiline settings field. For example:
request-retry: 5
routing:
strategy: fill-first
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 to pin it.
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 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.
