Can a model be made using onlyfans (not the usual porn sites data ) images available in the free sites or simpcity so that a realistic poses and faces can be generated. if there is already there please point it out

Using selfmade onlyfans model for more realistic poses but flexibility in faces using a lot of images

I don't see why not. Assembling a collection of well captioned images seems to be the bottleneck though. There is a model trained on nsfw subreddits called Subreddit V3, but it seems the images were only tagged based on the subreddit name and image quality, so its not really possible to prompt for much besides that. If you merge enough % of other models with it, it does become more flexible, but still produces similar faces.
