Seedance 2.5 is live on iApp — 30-second AI videos from text, image, video or audio references
· One min read
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.
