Seedance 2.5 Review: What It's Best At and When to Use It
Article image or reusable cover for OpenRouter
Seedance 2.5 is ByteDance's video model that can generate up to 30 seconds of video in 480p or 720p resolution.
It costs approximately $0.10 per second in 480p and $0.23 per second in 720p. The model excels at capturing long shots and editing or extending existing video — when you input an existing video clip, it costs roughly 40 percent less than generating from scratch. Compared to the earlier version Seedance 2.0, 2.5 can produce longer video clips (30 seconds instead of 15), but it only reaches up to 720p instead of 4K resolution.
Seedance 2.5 has been live on our video API since August 7, 2026, and as of September 3, 2026, the model page lists it from $0.1028 per second of generated video, which is what 480p works out to.
