OpenCode

Setup

1. 1

   Create a Relay API key in the console.

2. 2

   Save the provider block to ~/.config/opencode/opencode.json (or a project-level opencode.json) — it registers relay on the OpenAI-compatible endpoint.

3. 3

   Replace YOUR_MODEL_ID with a catalog model, then launch opencode and select relay/YOUR_MODEL_ID.
