GitHub Copilot

​
What is GitHub Copilot?

GitHub Copilot is GitHub’s AI coding assistant. It provides access to Copilot models for your GitHub account and plan. Fased can use Copilot as a model provider in two different ways. GitHub Copilot is a current Fased model provider route. It is separate from GitHub repository integrations or the GitHub plugin connector; this page only covers model access.

​
Two ways to use Copilot in Fased

​
1) Built-in GitHub Copilot provider (github-copilot)

Use the native device-login flow to obtain a GitHub token, then exchange it for Copilot API tokens when Fased runs. This is the default and simplest path because it does not require VS Code.

​
2) Copilot Proxy plugin (copilot-proxy)

Use the Copilot Proxy VS Code extension as a local bridge. Fased talks to the proxy’s /v1 endpoint and uses the model list you configure there. Choose this when you already run Copilot Proxy in VS Code or need to route through it. You must enable the plugin and keep the VS Code extension running.

​
CLI setup

fased models auth login-github-copilot
You’ll be prompted to visit a URL and enter a one-time code. Keep the terminal open until it completes.

​
Optional flags

fased models auth login-github-copilot --profile-id github-copilot:work
fased models auth login-github-copilot --yes

​
Choose a model

For normal browser setup, open Agents, select the Agent, then use Agent > Models to choose a GitHub Copilot model for primary, fallback, or task work. For CLI setup, you can set the default model: 
fased models set github-copilot/gpt-5.5

​
Config snippet

{
  agents: { defaults: { model: { primary: "github-copilot/gpt-5.5" } } },
}

Notes

  • Requires an interactive TTY; run it directly in a terminal.
  • Copilot model availability depends on your plan; if a model is rejected, try another current Copilot model ID (for example github-copilot/gpt-5.4 or github-copilot/claude-sonnet-4.6).
  • The login stores a GitHub token in the auth profile store and exchanges it for a Copilot API token when Fased runs.
