seedance-2-0-fast Seedance speed tier — frontier motion, 720p cap, ~20% cheaper.
No GPU. No setup. Cancel anytime.
Seedance 2.0 Fast trades the 1080p ceiling for quicker turnaround and a lower rate — the right tier for drafts and social-format output from the Seedance line.
Same reference system and partner-model rules as Seedance 2.0: Premium Spark only, no negative prompts, fixed 24 fps.
Seedance 2.0 Fast exposes these workflow variants — pass the matching model id.
| Workflow | Model id |
|---|---|
| Text → video | seedance-2-0-fast |
| Image → video | seedance-2-0-fast |
| Image + audio → video | seedance-2-0-fast |
| Video → video | seedance-2-0-fast |
On the Sogni API you pay per clip in Spark (1 Spark = $0.005). Prefer a flat rate? The Sogni app runs Seedance 2.0 Fast and 100+ other models credit-free under fair use.
| Configuration | Spark | USD |
|---|---|---|
| 5 s · 720p | 156 Spark | $0.78 |
| 5 s · 720p · video reference (v2v) | 92.4 Spark | $0.46 |
Premium Spark required — purchased credits; no SOGNI fallback.

Most platforms ration credits or rent a cloud GPU by the hour. Sogni gives you a flat monthly price for credit-free fair-use generation, powered by a creator-owned GPU network — or per-render Spark pricing if you'd rather pay as you go via the API.
One flat price in the app. Generate under fair use without a per-image meter.
Image, video, music, and language models in one workspace and one API key.
