# OpenCode with zurelay

> Open-source coding agent for the terminal. Made by SST.

Source: https://zurelay.com/docs/integrations/opencode

The examples use `claude-opus-5-5`. Any model ID from [the models page](https://zurelay.com/docs/models) works.

## Set it up

1. Export `ZURELAY_API_KEY` in your shell profile.
2. Add zurelay as a provider in `~/.config/opencode/opencode.json`, or in `opencode.json` at your project root.
3. Run `opencode` and switch models any time with `/models`.

## Configuration

opencode.json (`~/.config/opencode/opencode.json`):

> **Note:** Keep the `@ai-sdk/openai-compatible` package: it calls Chat Completions, which every zurelay model supports. `small_model` handles titles and other quick jobs.
