Seedance 2.0 Fast

Speed-first Seedance video generation for high-volume iteration.

A faster, lower-cost Seedance route for text-to-video, first and last frame control, and multimodal reference-to-video. It prioritizes generation speed and cost over maximum output quality, and renders up to 720p.

Video routes are billed per second of output. Rates follow OpenRouter's token formula, tokens = height x width x duration x 24 / 1024, and generating audio does not change the rate. Passing a video as reference uses a lower rate.
