Funny thing is I couldnt resist downloading it to try what is so secret here....and it's actually really good and now I wonder what this is.

Is this a PONY type model?

ok, go ahead and pass on this mystery checkpoint folks. i tested this out a little bit, and i would say it's not very good nor special. Posing isn't good, prompt adherence isn't good, it has a strong face bias that looks kind of Japanese-Philippino-Thai-Malaysian. It doesn't seem to be particularly trained on NSFW content nor is the image quality very good, very blurry most of the time with bland coloring and faces that needed an ADetailer pass to not be distorted. That was what I could determine from about 15 minutes messing with it.

no big special mystery super-checkpoint here.

I got some good sharp images from it, gorgeous actually. Im going to test it out more and maybe use it in a merger
