Seedance 2.0 Fast

by ByteDance

Released in February 2026 alongside the flagship, Seedance 2.0 Fast is the speed-optimized cut of ByteDance's second-generation video model. It preserves the full 2.0 input surface, text prompts, subject-reference images, and natively synchronized audio, while tuning the pipeline for shorter render times. The tradeoff is resolution, with output capped at 480p or 720p rather than the flagship's higher ceilings, while duration still spans 4 to 15 seconds. Choose it when someone is waiting on the result, for in-app generation, rapid creative iteration, and high-volume social content where turnaround beats pixel count.
