What Seedance 2.5 can do

- Timestamp-level editing, as described in the launch post.
How you use it
Seedance 2.5 is hosted and API-only. There are no public weights stated in the launch post, so you do not download and run the model yourself. The app route is Dreamina, which needs sign-in. Re-check the official pages before you pay or sign up.
What this means for making videos
Seedance 2.5 is a strong hosted video maker, but it is not a free, no-sign-in route. For finished videos without signing in, making them here remains the practical route. The other release in this news section is LTX-2.5, the open-weights model that needs a big GPU.
Prices and limits change. Re-check the official page before you pay, sign up or download anything. No quote, screenshot or image is shown on this page.
