ByteDance has released Seedance 2.5, the latest version of its Seed video-generation model. The model can generate a 30-second high-quality video clip in a single run and supports multi-turn extension for longer sequences.

Users can provide up to 30 images, 10 videos and 10 audio clips as reference material in one input. The model is being rolled out to Jimeng AI and the Pro version of Doubao, while an API is expected to arrive soon on Volcano Engine’s Ark platform.
