Why Choose Kie.ai 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 /api/v1/jobs/createTask, so one Kie.ai 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 above. Pricing for each resolution is shown in the pricing card above.

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, while reference images and reference audio add no billable seconds. With automatic duration, billing follows the length actually generated. New Kie.ai users receive 80 free credits for testing.
