Seedance 2.5 is ByteDance's latest AI video generation model, built to create native 4K cinematic videos up to 30 seconds long from text prompts, images, audio, video clips, and multimodal references.

Compared with earlier versions, Seedance 2.5 focuses on producing longer, more coherent videos while reducing the need for stitching multiple clips together during post-production.

How does Seedance 2.5 work? Seedance 2.5 is powered by a multimodal AI video generation architecture that understands text, images, audio, video, and multiple reference assets within a single workflow.
