No official confirmation I’ve seen beyond ByteDance’s own teasers, so treat any exact date as a rumor until it shows up on their actual channels. These global rollouts also tend to slip a day or two, or launch in phases by region, so don’t be surprised if US access lags behind. If you don’t want to wait around, there’s pay as you go access to Seedance 2.5 at https://vidhapi.app/generate-seedance-2-5 and the cheaper Seedance 2 Fast at https://vidhapi.app/generate-seedance-2-fast, no subscription needed, which is nice if you just want to test it once.
