## When to pick this model (vs siblings)

| You want | Use |
|---|---|
| Multi-shot story with character / wardrobe consistency | **HappyHorse 1.0** |
| Native audio in the same generation pass | **HappyHorse 1.0** |
| Currently-#1 blind-vote video model | **HappyHorse 1.0** |
| Detailed lip-synced dialogue + reference video | Seedance 2.0 Pro |
| Fine motion control + multi-reference conditioning | Wan 2.7 |
| Ultra-fast iteration (sub-second per frame) | LTX 2 |
| Cinematic motion editing on existing footage | Kling Video O1 |

If the user said "HappyHorse" / "happy horse video" explicitly, route here regardless.

## Prerequisites

1. **RunComfy CLI** — `npm i -g @runcomfy/cli`
2. **RunComfy account** — `runcomfy login` opens a browser device-code flow.
3. **CI / containers** — set `RUNCOMFY_TOKEN=<token>` instead of `runcomfy login`.

## How to invoke

**Default (16:9 1080p 5s):**

```bash
runcomfy run happyhorse/happyhorse-1-0/text-to-video \
  --input '{"prompt": "<user prompt>"}' \
  --output-dir <absolute/path>
```

**Vertical short (9:16, 8s, no watermark):**

```bash
runcomfy run happyhorse/happyhorse-1-0/text-to-video \
  --input '{
    "prompt": "<user prompt>",
    "aspect_ratio": "9:16",
    "duration": 8,
    "watermark": false
  }' \
  --output-dir <absolute/path>
```

**Cheaper test pass (720p):**

```bash
runcomfy run happyhorse/happyhorse-1-0/text-to-video \
  --input '{"prompt": "<user prompt>", "resolution": "720P", "duration": 3}' \
  --output-dir <absolute/path>
```

The CLI submits, polls every 2s until terminal, then downloads any `*.runcomfy.net` / `*.runcomfy.com` URL from the result into `--output-dir`. Stdout is the result JSON. Stderr is progress.
