Wingman AI — VS Code Extension
This extension integrates the Wingman AI platform into VS Code's Copilot Chat by configuring the built-in "Custom Endpoint" language model provider that ships with VS Code (1.123+). It auto-discovers the models available on your Wingman backend and registers them as a "Wingman" language model group — VS Code itself handles all chat traffic (OpenAI Responses API, streaming, tool calling, thinking, images).
⚠️ Important Notice: This extension requires the Wingman AI Platform and should not be installed unless you are running a compatible Wingman backend.
How it works
On first startup (and whenever you run Wingman: Sync Models), the extension:
- Queries
GET {baseUrl}/models on your Wingman backend
- Matches the reported model IDs against its model catalog (names, token limits, capabilities, reasoning effort levels)
- Registers a Wingman provider group with VS Code's built-in
customendpoint vendor (apiType: responses, zeroDataRetentionEnabled: true — requests are stateless, no previous_response_id is ever sent)
After that, the models appear in the Copilot Chat model picker. The resulting configuration lives in your VS Code profile's chatLanguageModels.json (command: Open Language Models File) and can be edited or removed there — re-running Wingman: Sync Models after removal re-creates it.
Features
- Native Copilot Chat integration — uses VS Code's built-in OpenAI-compatible provider; no custom wire protocol code
- Multi-vendor model support — automatically discovers available models from your backend
- Zero Data Retention — Responses API in stateless mode (
store: false, no previous_response_id)
- Tool calling, vision, thinking — capabilities forwarded per model
- Reasoning controls — per-model "Thinking Effort" picker where supported
