Seedance 2.5 API exposes ByteDance's next-generation audio-video foundation model for production AI video with native 30-second single-pass clips, up to 50 multimodal references, first/last-frame control, region-level edits, and stronger continuity for ads, e-commerce, and film previs.
Generate a 480p draft first, then create a 1080p final video when you are happy with it. Each generation is billed separately.
Explicit types validate task constraints before creation. The prompt must still match the selected type or TaskTypeMismatch may fail asynchronously.
First/last frame tasks require Adaptive. When video or audio references are present, frame roles are treated as reference images.
Upload reference audio
WAV, MP3 (max 15MB, up to 10 audios, duration ≤ 30s)

Answers about Seedance 2.5 API capabilities, workflows, and usage
The Seedance 2.5 API refers to programmatic access to ByteDance's audio-video model for text, image, and reference-guided AI video generation with production controls. Seedance 2.5 expands earlier Seedance workflows for longer clips and tighter Seedance subject control.
Seedance 2.5 extends earlier Seedance models such as Seedance 2.0 toward longer clips and tighter subject control. The Seedance 2.5 API offers native single-pass clips up to about 30 seconds, up to about 50 multimodal references across images, video, and audio, region-level edits, and 3D camera blockouts for production continuity. Both models are available on 光谱汇深 with the same API key.
Seedance 2.5 API supports native single-pass clips up to about 30 seconds, reducing the need to stitch multiple short generations for short-form production.
Seedance 2.5 API supports up to about 50 multimodal inputs spanning images, video, and audio.
Supported workflows include text-to-video, image-to-video with first/last-frame control, and reference-guided generation for product consistency, brand style, and multi-shot storytelling.
Seedance 2.5 API supports synchronized sound and dialogue-driven clips as an audio-video foundation model.
Seedance 2.5 API follows an asynchronous job flow: submit a generation request, receive a task ID, then poll or use webhooks before downloading the result.
Full request parameters and code examples for Seedance 2.5 video generation are in the 光谱汇深 docs (docs.callhub.cn). Authenticate with your 光谱汇深 API key, submit a generation request, and use the returned task ID to poll for the result (or receive it via webhook) before downloading the video.
The ByteDance Seedance 2.5 API is settled by actual token usage. The per-resolution rates in this page's pricing table are precharge estimates, and successful tasks are reconciled against the tokens actually used. The table lists every specification at Gold member prices (20% off); Platinum and Diamond members save more, up to 28%. You only pay for successful requests.
