ByteDance Seedance 2.0 Fast
ByteDance's low-latency Seedance 2.0 tier — quick 480p/720p generation with synchronized audio.
Seedance 2.0 Fast is a cloud video-generation model built by ByteDance. It produces short video clips from a text prompt, a starting image, or by interpolating between a first and last frame. Clips run up to 15s at 720p with a synchronized audio track. It also supports seed control and reference images. It runs through Runware, OpenRouter, Replicate, and ByteDance using your own API key, from about $0.0907 per second of output.
