So I have been alerted to this, and while I cannot use it yet myself because I lack a needed gpu with between 9-12 gb of vram, this may help a lot of other people.

It also has an automatic repo extension that you can download it from.
Supposedly, it can create an accurate embedding with a SINGLE image that can be used for various new creations.
I say supposedly, because I personally can't use it yet, and I don't see a collab yet for it. But, if it works as advertised, perhaps this would create real progress toward the ultimate goal?
