Why Choose ModelFold for Seedance 2.5 API Access
Seedance 2.0, 2.0 Fast, 2.0 Mini and 2.5 on One Endpoint
bytedance/seedance-2-5, bytedance/seedance-2, bytedance/seedance-2-fast and bytedance/seedance-2-mini all run on POST https://ai.modelfold.online/v1/videos/generations, so one ModelFold API key lets you compare them on the same prompt. Seedance 2.5 outputs 480p to 1080p video from 4 to 30 seconds with audio on by default; the full parameter list is in the Playground and API docs on this page. Pricing for each resolution is shown in the pricing line above and in the rate card of the API section.
First Frame, First and Last Frames, or References
Image-to-video from a first frame, image-to-video from first and last frames, and multimodal reference-to-video (reference images, videos and audio) are three separate modes that cannot be combined in one request, and a last frame always needs a first frame. When the opening and closing shots must match specific images exactly, use first and last frames rather than references.
Reference Videos Add Billable Seconds
With reference videos, billing counts the total reference-video duration plus the output duration at a lower per-second rate (each reference video is rounded up to a whole second, and a request never costs less than the same clip without a reference video), while reference images and reference audio add no billable seconds. With automatic duration (-1), the request is charged for the 30-second maximum. New ModelFold users receive 80 free credits for testing.

Billed per second. The price above is for a 5-second clip at each resolution — longer clips cost proportionally more, and the Playground charges the exact same way.
With reference video(s): cost = the per-second price above × (total reference-video seconds + output seconds). Each reference video is rounded up to a whole second, and the total is never lower than the same clip without a reference video. Reference images and audio add no billable seconds. Duration -1 (auto) is charged as 30 seconds.
