Seedance 2.0 by ByteDance — that very video model — is now live in Runway and HeyGen. The clip above was made entirely in Runway on the new model.
Until now Seedance was only accessible through its native interfaces, so trying it in a production workflow was clunky. Now you can plug it straight into Runway's timeline or use it inside HeyGen's presentation assistant.
One caveat: after the copyright drama ByteDance ran into this spring, the model now responds very cautiously to prompts with recognizable faces, brands, and especially reference images. So don't expect Veo-level obedience to references just yet.
Free to try on both platforms.
