OpenCode

OpenCode uses one configuration file:

~/.config/opencode/opencode.json

You can also use opencode.jsonc. Create the file manually if it does not exist.

Choose the provider example that matches the group assigned to your CE API key. The base URL and API key under API Keys -> Use Key take precedence over the placeholders below.
