Seedance 2.5 is live on iApp — 30-second AI videos from text, image, video or audio references
Dreamina Seedance 2.5 is now available through the iApp platform, sitting alongside Seedance 2.0 on the same endpoint and the same API key. BytePlus released it on 7 August 2026; it is live on iApp today.
The headline change is length. Seedance 2.0 renders 5-second clips; 2.5 renders up to 30 seconds — long enough for a complete product spot or a scene with a beginning, middle, and end, rather than a loop you have to stitch. Motion is noticeably steadier over that longer window, and the model holds a subject's identity across shots far better than 2.0 did.
