Features

• Native model picker — your subscription models appear under Universal Chat Provider in Copilot Chat, with context, output, tool, image, and reasoning metadata.
• Reasoning support — models with multiple reasoning levels use VS Code's built-in selector, and emitted reasoning summaries stream into a collapsible thinking block.
• Utility model — point Copilot's commit messages, chat titles, and summaries at your subscription models with one command. No Copilot subscription required.
• Zero setup (managed mode) — the extension downloads, verifies, and supervises the proxy for you; one shared server across all windows.

Supported logins

Sign in with any subscription you already have — no API key:

• 🟣 Claude — Claude Code / Pro / Max
• 🟢 Codex — ChatGPT Plus / Pro
• ⚪ Grok — Grok Build
• 🟡 Kimi — Moonshot
• ⚫ Antigravity

Quick start

Requires VS Code 1.124+ and the GitHub Copilot Chat extension.

1. Install — get Universal Chat Provider from the VS Code Marketplace. Prefer to build it yourself? See Development.
2. 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.
3. 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 — list/remove accounts, restart, update, or reset the managed server.

External mode — bring your own CLIProxyAPI server

Prefer to run CLIProxyAPI yourself (e.g. a remote or shared instance)?

1. Set universalChatProvider.server.mode to external.
2. Start CLIProxyAPI and complete the provider login there.
3. Use the Import API Key notification action (when a local config is found) or Configure Connection to set 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. If your server exposes a plaintext remote-management.secret-key, the Add Account and Manage Accounts commands work against it too.

Utility model

Copilot generates commit messages, chat titles, and summaries with its own background models. Run Universal Chat Provider: Set Utility Model (or use the status bar menu) to point Copilot's chat.utilityModel and chat.utilitySmallModel at one of your subscription models instead, so those background flows run through your accounts. 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. Clear the selection to undo.

How it works

GitHub Copilot Chat normally only talks to Copilot's own models. This extension bridges that gap: it runs a local CLIProxyAPI server, logs you into your AI subscriptions via OAuth, and registers their models as a native chat provider in VS Code. Pick them straight from the Copilot model dropdown.
