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.
4–30-second output
Generate 5, 8, 10, 15, 20, 25, or 30-second clips, with 5 seconds as the default.
Up to 1080p output
Generate at 480p, 720p, or 1080p. The legacy page listed 480p and 720p; PiAPI now also supports 1080p generation.
Standard and Less Restriction
Use seedance-2.5 for the standard workflow. The seedance-2.5-less-restriction task type supports generation with face assets after they pass Private Asset Library review.
Multimodal references
Use image, video, and audio references to guide the result. 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.
Production API workflow
Test the live Seedance 2.5 task in the playground, then reuse the same model, task type, prompt, and reference contract in your application.
Flexible aspect ratios
Create in 21:9, 16:9, 9:16, 4:3, 1:1, or 3:4. When an image reference is supplied, its aspect ratio takes precedence.
Transparent usage billing
Output duration is billed at the selected resolution rate. When video references are used, input-video duration is billed at half of that rate.
From playground to API
Prepare the prompt and references, generate with model seedance and a Seedance 2.5 task type, then carry the tested request into your application.

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 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 resolutions does Seedance 2.5 support?
The API accepts integer durations from 4 to 30 seconds and supports 480p, 720p, and 1080p output.
What references can I use?
You can provide image, video, and audio references supported by the playground. Use @imageN, @videoN, and @audioN placeholders in the prompt.
How much does Seedance 2.5 cost?
Seedance 2.5 is billed per generated second, with rates based on the selected resolution and task type. See the pricing section above for the current dynamically sourced rates.
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.
How does Seedance 2.5 compare with Seedance 2.0?
Seedance 2.5 has dedicated standard and Less Restriction task types, supports up to 1080p output, and accepts multimodal references. Seedance 2.0 remains available for existing workflows and its own model variants.
What is Seedance 2.5 Less Restriction?
