GitHub Copilot
A GitHub subscription. A foreign OpenAI key will not go in.
This app will not take a foreign key. Not a cabinet bug — it only accepts its own login or a different protocol.
Do it in order. Don’t skip
Copilot Chat in VS Code talks to GitHub’s models. No Base URL field for cheapai.
To write in the same VS Code with your key — Cline, Roo, Kilo, Continue, or Claude Code.
Check
Don’t hunt for an OpenAI endpoint in Copilot settings — it isn’t there.
If it didn’t start
- Not a 401 and not a wrong Base URL. The app simply will not take a foreign key.
- Use Cursor, Cline, Claude Code, or OpenCode — those take the three fields from the cabinet.
