This is just BB95 Furry Mix with better buttholes.

All I have done is merge BB95 with a gaping/large insertion model as per the instructions here. TL;DR is that it adds gapes to BB95 using: Ass Mix = BB95 + (Gape model - NAI model)

All credit goes to Bumblebee95 for the excellent BB95 Furry Mix. Please look at their model and give any support to them.

For instructions on use, anything on the BB95 page is right and should apply to this model too. Personally I prefer to use DDIM at 512*704 with 1.5 Hires Fix by Latent (nearest). Around 7.5-9 CFG scale works well, 0.6-0.7 denoising and I usually use around 30-80 steps (clip skip 1). These might be outdated with newer versions of BB95, check that model's page for instructions.

Images are the same seed with the same settings made on BB95v_?_ then BB95v_?_AssMix. BB95 are on the left and BB95 AssMix are on the right. Some are quite similar and some results are very different but I think all have better buttholes in this model, if you're the same kind of degenerate as I am.

I strongly recommend using e621 tags and looking up images on e621 to see what the correct tags are (e.g., 'scut tail' instead of 'deer tail') as they will work much better, gelbooru tags may also work because of the merged model.
