Embeddings, text inversion, VAEs...

Or in short "extensions" that allow the models do what they can't by themselves. Note that not every such extension works with every model. Just try it and see. Many of these list some models that they work with.

Currently just list of links, more details later. Also includes models until I get it sorted.

Note that some of these links might be NSFW. Login should be required for such content, but I cannot guarantee that all content available without it will be safe.
