Faster Seedance generation for prompt iteration, draft variants, and client previews.
Seedance 2.0 Mini
Lower-cost Seedance model for high-volume tests, rough cuts, and lightweight creative exploration.
Model specifications side by side
Every value below is read from the same configuration the generator validates against, so this table cannot drift from what the API actually accepts. Upstream model IDs are BytePlus public catalog names — you can verify each model's limits in their documentation.
| Model | Best for | Duration | Resolution | Aspect ratios | Image input | Credits / second |
|---|---|---|---|---|---|---|
Seedance 2.5dreamina-seedance-2-5-260628 | Longest clips, omni reference, audio-only input | 4–30s | 480P / 720P / 1080P | 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, adaptive | Yes | 16.6 |
Seedance 2.0dreamina-seedance-2-0-260128 | Highest resolution, up to 4K | 4–15s | 480P / 720P / 1080P / 4K | 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, adaptive | Yes | 11.4 |
Seedance 2.0 Fastdreamina-seedance-2-0-fast-260128 | Faster turnaround at lower cost | 4–15s | 480P / 720P | 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, adaptive | Yes | 7.4 |
Seedance 2.0 Minidreamina-seedance-2-0-mini-260615 | Cheapest per second, for drafts | 4–15s | 480P / 720P | 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, adaptive | Yes | 5.8 |
Credits per second are quoted at each model's lowest resolution so the four are directly comparable; the generator quotes the exact cost for your chosen settings before anything is charged. 1080P output on Seedance 2.5 is H.265/HEVC — a few browsers need a download to play it.
Deciding between the two standard tiers? Seedance 2.5 vs 2.0: which to use compares them job by job.
Reference input limits
Reference-to-video accepts images, video, and audio together. These are the per-model ceilings the API enforces — exceed one and the request is rejected before it reaches the model, so nothing is charged.
| Model | Reference images | Reference videos | Reference audio | Reference video length | Audio-only input | First / last frame |
|---|---|---|---|---|---|---|
| Seedance 2.5 | 30 | 10 | 10 | 2–30s | Yes | Up to 2 |
| Seedance 2.0 | 9 | 3 | 3 | 2–15s | No | Up to 2 |
| Seedance 2.0 Fast | 9 | 3 | 3 | 2–15s | No | Up to 2 |
| Seedance 2.0 Mini | 9 | 3 | 3 | 2–15s | No | Up to 2 |
Reference video is capped on total length as well as per clip: Seedance 2.5 accepts up to 30 seconds across all clips combined, the 2.0 family up to 15. Audio-only generation — no image, no video — works on Seedance 2.5 only.
What the models reject, and what to do instead
These are the rejections that actually happen in production, not a generic policy summary. Credits frozen for a rejected job are released automatically.
Photos of real people
Every Seedance model refuses to animate a recognizable real face, including your own and including images you hold the rights to. Switching models does not help — the check is upstream of all four. The compliant path is to create a character under Assets from that image, then reference the character instead.
Reference video under 2 seconds
A motion reference shorter than the minimum is rejected on submission. This is about the reference clip's own length, not the length of the video you are generating — a 5-second output from a 1.5-second reference still fails.
Deleted or still-processing assets
A reference to an asset that was deleted after you selected it fails upstream, and retrying will never succeed. Reopen the character picker and select again — stale selections are dropped automatically when it reloads.
Prompts that trip content review
Prompt-level rejections name the prompt, not your reference material. Rewording usually clears it; on Seedance 2.5 specifically, some prompts that fail there pass on Seedance 2.0.
