Video

Seedance 2.5*

Most advanced Seedance with 30s clips, native audio, and up to 50 references. Default choice for most video generations — quality is head and shoulders above other models, and it supports durations up to 30 seconds. Reach for this first unless the user asks for a specific model, needs 1080p or 4k output, or cost is the priority.

  • This API endpoint includes Krea prompt enhancement in addition to the base Seedance 2.5 model.
