Use Magic Router models directly from the GitHub Copilot Chat model picker.
Magic Router for Copilot does not replace Copilot Chat or add a separate chat UI. It registers Magic Router as a Copilot language model provider, so you can keep using Copilot Chat, Agent mode, workspace context, instructions, and tools while sending model requests through your own OpenAI-compatible router endpoint.
