Wan2.1-VACE: Alibaba adds a single model for creating and editing video to Wan 2.1
In one sentence On May 14, 2025 Alibaba releases Wan2.1-VACE 1.3B and 14B (Apache 2.0): one model for reference-based generation, video-to-video editing and masked editing, built on the VACE framework Tongyi Lab presented in March.
Generating a video from scratch is one thing; modifying an existing video coherently is harder. VACE is an Alibaba (Tongyi Lab) model that puts video creation and video editing in the same system.
With the Wan 2.1-based versions, released on May 14, 2025, you can generate a video from reference images, transform an existing video, or edit only an area marked by a mask. The authors cite uses such as moving, swapping or animating a subject and expanding the frame.
There are two models: a small 1.3-billion-parameter one (about 480p) and a 14-billion-parameter one (about 720p), both Apache 2.0.
