Seedance 2 Fast
Seedance 2 Fast is the accelerated variant of ByteDance's Seedance 2 video generation model, optimized for faster turnaround without sacrificing core quality. It supports text-to-video and image-to-video generation with first/last frame control, 720p resolution, and native audio generation, all at a lower cost per generation than the standard Seedance 2 model. It also takes up to 9 reference images, 3 video clips, and 3 audio files for multi-reference guidance; reference audio needs at least one reference image or video beside it.

There are no seat fees, feature gates, or plans on Layer. Instead, our platform uses a consumption based system with Creative Units (CUs) with a flexible monthly subscription. Every generation on Layer (image, video, 3D, or audio) consumes a Creative Unit, and you only pay for what you create.
