Bytedance Seedance is a browser-based AI video generation platform that runs ByteDance's Seedance 2.0 model, the top-ranked video generator on Artificial Analysis for image-to-video with audio. It accepts text, up to nine reference images, three video clips, and three audio tracks as input, and outputs up to 2K resolution clips with native audio—dialogue, sound effects, and music generated in a single pass using the Dual-Branch Diffusion Transformer architecture.
