Seedance 2.5 API overview
Seedance 2.5 is ByteDance's multimodal video model, and its official developer API is live as of August 7, 2026. The site tracks official facts separately from provider availability and highlights two access routes: the official BytePlus/Volcengine ModelArk API and the EvoLink integration. It covers workflow-specific model IDs for text-to-video, image-to-video, and reference-to-video, supports 4–30 second durations and 480p/720p resolutions, offers asynchronous generation with task polling, provides a request builder, example prompts, machine-readable endpoints for coding agents, and retains Seedance 2.0 as a rollback option.
