Understanding Wan models

I keep stumbling across wan video generation terms, such as wan animate, wan scail, wan steady dance and was wondering if they are a type of technology that some of the wan models feature or if they are their own video models. These are the official hf wan 2.2 models attached, but I don't seem to find wan scail and wan steady dance. Also, what is the difference of the diffusers and the non-diffusers? submitted by /u/DeLaMexico [link] [comments]
