Seedance 2.0

High-fidelity video generation with reference-guided character and style consistency.

ByteDance's flagship Seedance route for text-to-video, first and last frame control, and multimodal reference-to-video. It is particularly strong at preserving character consistency, visual style, and camera movement from reference material, and it is the only Seedance route here that renders up to 4K.

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.
