Seedance 2.5 capabilities
A focused contract for richer video workflows
Seedance 2.5 keeps the proven Seedance request shape while defining a clear model, resolution, duration, reference, and pricing contract.
480p and 720p output
Generate at 480p or 720p, with 720p as the default. Seedance 2.5 does not support 1080p.
Standard and Less Restriction
Submit model seedance with task_type seedance-2.5 or seedance-2.5-less-restriction; there are no fast or mini variants.
Multimodal references
Use up to 9 images, 3 videos, and 3 audio files. Reference-image aspect ratio takes precedence over the requested aspect ratio.
Reference placeholders
Refer to supplied media directly in the prompt with @image1, @video1, and @audio1 placeholders.
Audio requirements
Audio references require at least one image or video reference. Audio total duration is limited to 15 seconds.

Frequently asked questions
Seedance 2.5 on PiAPI
What is Seedance 2.5?
Seedance 2.5 is a Seedance AI video task on PiAPI. Use model seedance with task_type seedance-2.5 or seedance-2.5-less-restriction to generate 480p or 720p video from a prompt, optionally guided by image, video, or audio references.
Can I use the Seedance 2.5 playground on PiAPI?
Yes. The Seedance 2.5 playground is live on this page and lets you select the standard or Less Restriction task type.
What duration and aspect ratios does Seedance 2.5 support?
The API accepts integer durations from 4 to 30 seconds. Available aspect ratios are 21:9, 16:9, 9:16, 4:3, 1:1, and 3:4; a supplied reference image takes precedence.
What references can I use?
You can provide up to 9 image URLs, 3 video URLs, and 3 audio URLs. Audio references require at least one image or video reference. Use @imageN, @videoN, and @audioN placeholders in the prompt.
How much does Seedance 2.5 cost?
The standard task costs $0.15 per output second at 480p and $0.35 per output second at 720p. Seedance 2.5 Less Restriction costs $0.165/s at 480p and $0.385/s at 720p. When video references are used, input-video duration is billed at half the selected output rate.
Can I integrate the Seedance 2.5 API now?
Yes. Create a PiAPI task with model seedance and either Seedance 2.5 task type, then provide the prompt, duration, resolution, aspect ratio, and any supported reference URLs.
Does Seedance 2.5 support 1080p or private asset:// references?
No. The current contract supports 480p and 720p only, and documents publicly accessible media URLs for references.
