ByteDance (Seedance 2.5)
Up to thirty reference images in one request, with sound generated alongside the picture. ByteDance Seedance 2.5 — up to 30 reference images, with native audio.
Using Seedance 2.5 in uooki
uooki has no model picker. You name the model in the conversation and the agent routes to it — “make the clip with Seedance 2.5” 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
- Work with a large pile of reference material to constrain the result
- Character consistency across a complex scene
- Video with sound generated together with the picture
Where it is not the right pick
Expensive. uooki runs it at 720p; the upstream 1080p tier costs about two and a half times as much and is not offered. In chat the sound is always on.
When to reach for something else
- Seedance 2.0
You want the same family at a lower price and nine reference images are enough.
- Kling O3
You have a few reference images and want top-tier motion.
- Veo 3.1
You want native audio without supplying reference material.
