README

Seedance 2 Fast provides the Seedance 2 creative workflow for faster, lower-cost video tasks with 4-15 second outputs, 480p/720p tiers, and token pricing by video input.
  • Seedance 2 Fast supports the same broad creative direction as Seedance 2, including multimodal reference workflows.
  • It is tuned for teams that want faster iteration and lower per-second cost while staying within 480p and 720p output tiers.
  • Use this model when Seedance 2 compatibility is useful but speed and lower per-second cost matter more than 1080p output.
