Seedance 1.5 Pro supports prompt-only video generation, first-frame image-to-video, and first-and-last-frame image-to-video. It can generate silent videos or synchronized audio when audio output is enabled. Use Seedance 1.5 Pro when you need compatibility with the upstream ModelArk 1.5 video generation surface. Draft mode exists upstream, but GenGen does not expose draft creation in the API Explorer or Playground.
