# Run on another model Three keys, three jobs: - **`~/.mulmoterminal/config.json` → `providers`** — register a backend once. No Settings UI. - **`<project>/.mulmoterminal.json` → `provider` / `model`** — what this project launches on. Both are defaults; the launch form can override them for a single session. - **`~/.mulmoterminal/config.json` → `customAgents`** — the user's own COMMAND for starting Claude Code, offered in the Agent Picker. For when the model is reached by running something else (`ollama launch claude …`, a wrapper script, a second Claude Code install) rather than by an HTTP endpoint. No Settings UI. None is needed to use Anthropic's default. Only do this when the user asked for another model. **Which one.** A backend that speaks the Anthropic API over HTTP is a `providers` entry — that is the smaller change and it composes with the model picker. Reach for `customAgents` only when the thing that runs the model is a **command**, and the user cannot express it as a base URL and a token. ## Registering a backend ```json { "providers": [ { "id": "openrouter", "label": "OpenRouter", "baseUrl": "https://openrouter.ai/api", "tokenEnv": "OPENROUTER_API_KEY", "maxOutputTokens": 16000 } ] } ``` Each rule below was measured against a working setup, and each breaks the session in a way that is hard to diagnose from inside it: - **`baseUrl` must not end in `/v1`.** Claude Code appends `/v1/messages` itself, so a tra...
