Using HappyHorse 1.1 in uooki
uooki has no model picker. You name the model in the conversation and the agent routes to it — “make the clip with HappyHorse 1.1” is the whole interface. Common spellings and older ids resolve to the same model, so you do not have to match our internal naming.
Leave the model out and the agent picks one for you based on what you asked for. Naming it is for when you have a reason to — this page is about those reasons.
What it is good at
- Give it a photo of a person and have them speak
- Talking-head and explainer clips
Where it is not the right pick
**The sound cannot be turned off** — upstream exposes no audio switch, so if you do not want sound, do not use this model.
When to reach for something else
- Veo 3.1
You want lip-sync you can also turn off, plus full scene control.
- Kling O3
The subject has to move through several shots, not just speak.
- Hailuo 2.3
You want silent image-to-video.
