SDXL: A merge of the SDXL Photoboobs checkpoint with a couple anime/art SDXL checkpoints. I'll probably make a new one - this one has a very high bias toward making white people over other races/ethnicities.

SD 1.5: A veritable soup of checkpoints I should have catalogued. These are a few that got mixed and re-mixed until I found a checkpoint I felt comfortable sharing:

https://civitai.com/models/79570?modelVersionId=84383
https://civitai.com/models/18637?modelVersionId=191384
https://civitai.com/models/219439?modelVersionId=247432
https://civitai.com/models/5245?modelVersionId=6087
Most of those are pretty horny checkpoints, so I'm gonna guess that NSFW stuff will come easily with this checkpoint, although I haven't checked that out yet.
