Opper for VS Code

Use Opper models in VS Code Copilot Chat, including Agent mode with supported models.

Get started

Install the extension.
Run Opper: Sign In from the Command Palette and approve in your browser.
Open Chat and choose an Opper model.

Use your existing Opper account, including your organization’s configured SSO. No Opper CLI installation or manual key copying is needed. Credentials are stored in VS Code’s secure storage.

Models and access

The model picker loads the models, pools, and dynamic routes available to your key. Your organization manages access and policies in Opper.

Use Opper: Account and Models to view your account, manage sign-in, or choose which model types appear.

Thinking effort

Run Opper: Set Thinking Effort, or choose Set thinking effort… from the Opper model menu. Select a model or pool, then one of the levels advertised by the gateway. Server default removes the override.

The selection is saved per API endpoint and exact model ID and applies across conversations. The model details show the saved effort. Explicit request options take precedence. A saved level that becomes unavailable blocks the request with instructions to choose another level or reset it.

Pools offer only efforts shared by their allowed members. Dynamic routes and models without effort metadata do not offer configurable levels. This uses a separate Opper control because VS Code’s native Thinking Effort submenu API is still proposed.

Usage and budget

Hover over Opper in the status bar for a usage summary. Click it to see your project’s spending, allowance, remaining amount, and reset date, where configured.

Organization billing details appear only when you have permission to view them.
