GitHub Copilot Integration

Connect your GitHub Copilot subscription to GetThatQuick and get free access to top-tier models — Claude Sonnet 4.5/4.6, Claude Opus 4.5/4.6, GPT-4.1, Gemini 2.5 Pro, and more.

Who can use this?
  • GitHub Copilot Individual (paid, $10/month)
  • GitHub Pro users (Copilot included)
  • Students with GitHub Education / Student Developer Pack — completely free
  • GitHub Copilot Business/Enterprise (may depend on org settings)

Setup​

1. Connect your account​

  1. Open Settings → Models & LLM
  2. At the top, click Connect GitHub Copilot
  3. A code like B5D7-1271 appears

2. Authorize on GitHub​

  1. Click the link to open github.com/login/device (or use the copy button)
  2. Enter your code
  3. Click Authorize on GitHub
  4. Return to GetThatQuick — it detects the authorization automatically

3. Select a model​

Once connected, a github-copilot provider appears in your providers list:

  1. Set it as the active provider (click "Use" next to it)
  2. Edit the provider and set a model, e.g. claude-sonnet-4.5
  3. Start chatting

Available Models​

After connecting, you can fetch available models via Settings → Models & LLM → github-copilot → (expand) → Load Models.

Common model IDs to try:

Model IDDescription
claude-sonnet-4.5Claude Sonnet 4.5 — fast, smart, great for coding
claude-sonnet-4.6Claude Sonnet 4.6 — latest Sonnet
claude-opus-4.5Claude Opus 4.5 — most capable Claude
gpt-4.1OpenAI's latest GPT
gpt-4oFast GPT-4 variant
gemini-2.5-proGoogle Gemini 2.5 Pro
note

Model availability depends on your Copilot plan. If a model returns a 404, try a different one.

How It Works​

Under the hood:

  1. GetThatQuick starts an OAuth device flow using the same client ID as VS Code's Copilot extension
  2. After you authorize, a GitHub OAuth token (gho_...) is stored as your provider's API key
  3. Before each request, the server automatically exchanges the gho_ token for a short-lived Copilot API token (valid ~30 minutes)
  4. The token is cached and refreshed transparently — you never need to re-authenticate

The Copilot API is OpenAI-compatible, so all of GetThatQuick's features (streaming, thinking tokens, plan mode, etc.) work normally.

Disconnecting​

  1. Settings → Models & LLM
  2. Click Disconnect next to the GitHub Copilot section
  3. The stored token is removed

You can reconnect at any time by repeating the setup steps.

Troubleshooting​

ProblemFix
Code expired before authorizingClick "Connect GitHub Copilot" again to get a new code
"Failed to get Copilot token"Token expired or revoked — disconnect and reconnect
Model returns 404That model isn't available on your plan — try another
No models appear in listMake sure the provider is connected and active
Rate limit errorsCopilot has request limits per plan; wait a few seconds

Privacy Note​

Your GitHub OAuth token is stored locally in ~/.getthatquick/config/settings.json. It never leaves your machine except to authenticate with GitHub and send requests to api.githubcopilot.com. All conversation data is stored locally as always.
