But isn't that model still mixed with the core SD model? I was under the impression that all of these specialized models are created by training against a particular image type/dataset, and then mixing the result with the core SD model. This is how those specialized models can still generate just about anything. Without the core model mixed in, the specialized model would be nearly useless.
