Seedance 2.0 vs Seedance 2.5
Seedance is ByteDance's video model family, the engine behind Dreamina and Jimeng and the model that made the biggest noise of 2026. Two are live on fal in September 2026: Seedance 2.0, the February release with native audio and up to 15 seconds, and Seedance 2.5, the July release that stretches to 30 seconds in one shot. Each has its own page with the same nine clips. Seedance 2.5 also has separate 20- and 30-second workflow tests from September 18; those do not replace the shared short-shot benchmark.
