Hanzo Engine: which models the serving runtime has loaded, and the GPUs under it.

[API reference →](https://docs.hanzo.ai/docs/openapi/engine)

```bash
hanzo engine model
```

Every command takes `--json` for the raw response and `--help` for its own flags. Sign in once with `hanzo auth login`; the commands below use that session, and the org they act in is the one it carries.
