What Happy Horse 1.0 can do
Happy Horse 1.0 is a 15-billion-parameter unified Transformer model built by Alibaba. It produces video and audio together from a single prompt, which sets it apart from models that require separate pipelines for visuals and sound.
Joint audio and video in Happy Horse 1.0
Happy Horse produces video and audio (dialogue, ambient sound, Foley effects) in a single forward pass. There is no need for a separate dubbing or sound design step. It supports native lip-sync in seven languages:

Happy Horse 1.0 camera control
The model is unusually responsive to camera language. Specific terms produce distinct, reliable results:
| Camera cue | What it produces | Best for |
|---|---|---|
| Steadicam push | Smooth forward movement | Walking scenes, reveals |
| Slow dolly-in | Gradual zoom from medium to close | Emotional moments, product focus |
| Lateral orbit | Side-to-side rotation with parallax | Product showcases, architecture |
| Helicopter aerial | Bird's-eye sweeping shot | Landscapes, establishing shots |
| Locked-off framing | Static camera, subject moves | Dialogue, interviews |
| Tracking shot | Camera follows subject movement | Action, walking sequences |
Put the camera cue at the end of your prompt. That is where Happy Horse 1.0 gives it the most weight.
Happy Horse 1.0 motion consistency
Subjects stay stable throughout the clip:

Prompting tips for Happy Horse 1.0
| Do | Don't |
|---|---|
| Start with your subject, action, and setting, then add one camera or lighting cue. Shorter prompts produce cleaner results, especially for single-character scenes. | Stack five cinematography cues in one prompt. They cancel each other out. |
| Use concrete lighting terms ("warm amber backlight," "overcast daylight," "sodium vapor street lamps"). | Use vague modifiers like "good lighting" or "beautiful atmosphere." |
| Put camera direction at the end of the prompt, where it gets the most weight. | Use slop words: stunning, epic, breathtaking, masterpiece, hyperrealistic, ultra detailed. |
| Use shot lists with timecodes for multi-beat scenes (e.g., Shot 1 wide 0-1s, Shot 2 mid tracking 1-4s). | Write multi-step action as plain prose ("first X, then Y, then Z"). It compresses into one motion. |
| Describe a visual style in technique terms ("backlit silhouette, soft natural haze, cool desaturated palette"). | Drop a director or DP name alone ("Roger Deakins cinematography") and expect it to carry the look. |
Happy Horse 1.0 responds best to plain English prose. In testing, structured formats like booru tags, JSON, and weighted parentheses underperformed against the same content written as a sentence. For longer prompts, shot lists with timecodes or markdown sections (Subject, Action, Setting, Camera, Lighting, Mood) help the model parse each element cleanly.
Example Happy Horse 1.0 prompts
A woman in a red coat walks through a rain-soaked Tokyo alley at night, neon signs reflecting off wet pavement, slow steadicam push forward.
Camera slowly orbits the subject, wind catches their hair, warm golden hour backlight, ambient city noise.
Shot 1 (0-2s): Wide shot of a coffee shop interior, morning light through windows, ambient chatter. Shot 2 (2-5s): Mid tracking shot follows a barista preparing a latte, sound of steaming milk. Shot 3 (5-8s): Close-up of the finished latte placed on the counter, soft piano in background.
