VS Code Copilot Chat (BYOK)

Also known as: Copilot BYOK

VS Code Copilot Chat (BYOK): configure models and providers in your editor.

Published instructions · App version: unverified

Chat, ping, invoke and content-generation examples may send real billable requests. Check the model, balance, rate and minimum before running them. GET /v1/models checks authentication and the catalogue only. Set up environment variables safely

Base URL to paste

OpenAI SDKs generally use a URL ending in /v1; Anthropic SDKs use the root URL. Avoid adding /v1 twice. Protocol compatibility does not guarantee every provider feature.

See notes / depends on the protocol

This app has exceptions — read Notes below before pasting.
