Tarification

Model / Resolution	4s	8s	12s	15s
seedance2-fast / 720p	30 (~$0.33)	65 (~$0.72)	95 (~$1.06)	120 (~$1.33)
seedance2 / 720p	40 (~$0.44)	80 (~$0.89)	120 (~$1.33)	150 (~$1.67)
seedance2 / 1080p	90 (~$1.00)	175 (~$1.94)	265 (~$2.94)	330 (~$3.67)

Prices are for the standard and wild modes with text/image inputs. The real mode costs about 1.4x. Omitting mode uses a separate fixed price table with slightly different totals. Video or audio references add per-second media-reference pricing.
