Which model to use
4 models, from cheapest to most capable.
| Model | Max length | Renders at | 480p → 4K, 5s |
|---|---|---|---|
| Seedance 2.5 | 30s | 480p, 720p, 1080p | $0.77 |
| Seedance 2.0 | 15s | 480p, 720p, 1080p | $0.59 |
| Seedance 2.0 Fast | 15s | 480p, 720p | $0.42 |
| Seedance 2.0 Mini | 15s | 480p, 720p | $0.26 |
Higher-numbered models follow instructions more reliably and hold detail better; the Fast and Mini builds trade some of that for price. If you are iterating on a prompt, iterate on a cheap model and do the final render on an expensive one — the prompt behaviour is similar enough to be useful.
Only some models render 1080p themselves. Where a model does not, that quality is not offered for it, and its route list on the composer is shorter.
