If you don’t have a Codex subscription, you can use your own OpenAI API key instead. Add it once in your Costa dashboard and Codex will route through it.
  1. Go to AI Providers in your Costa dashboard.
  2. Find the OpenAI row and open the ⋮ menu.
  3. Click Edit token and paste your OpenAI API key.
That’s it.
