VerifiedByteDance's multimodal video model that generates sound and picture together
Product preview
Seedance 2.0
What it is
Seedance 2.0 is a video generation model developed by ByteDance's Seed research team and introduced in February 2026. It uses a unified architecture that generates audio and video together rather than adding sound afterward. Prompts can combine text with reference images, audio and video clips, which gives creators direction over performance, lighting, shadows and camera movement. ByteDance reports strong motion stability and leading scores on its own SeedVideoBench-2.0 tests for text-to-video, image-to-video and multimodal tasks. The official page offers access through the Dola assistant, a BytePlus playground and a developer API, and the model is also offered through many third-party platforms.

Editor's notes
More context from AI BirdView
Most video models treat sound as an afterthought, if they handle it at all. Seedance 2.0 generates audio and picture in a single pass, so dialogue, effects and motion line up from the start. It also accepts a rich mix of references, letting creators guide a shot with images, audio and existing clips instead of relying on text alone. That makes it easier to keep characters, voices and style consistent across shots.
- A unified architecture that produces video and audio together
- Mixed inputs combining text, images, audio and video references
- Control over performance, lighting, shadows and camera movement
- Official access through ByteDance's Dola assistant and the BytePlus playground
- A developer API for building it into products
Seedance 2.0 is best for filmmakers, advertisers and content teams who want directed, cinematic clips with sound. A practical tip: many sites resell access under the Seedance name, so start from ByteDance's official Seed page to find the genuine playground and API before choosing a third-party platform. Short test clips with one or two strong reference images are a sensible way to learn how the model responds before planning longer or more complex sequences.
