While people have tried going from a base model to a fine tuned model based on explicit images, I wonder if there are people are attempting to go the other way round (train a base model on explicit photographs and other images not involving humans; then fine-tune away the explicit parts), which might lead to better results?
IMO finetuning is a waste of time unless you do cutting edge stuff.
Loras are just as powerful as a finetuned model and you can train one in minutes even on consumer hardware.
Do you have some more details on training a LoRA in minutes? Last I tried, it took several hours on an RTX 3090, but I am sure there have been improvements since then.
Tbh I mostly use loras others trained, there are hundreds around for all kinds of things
I first heard the "we need naked images to generate good clothed images" when SD3 came out and suddenly it's everywhere. But it just doesn't make any sense to me and as far as I know it wasn't explicitly practiced in previous popular models.
Is this process objectionable to you? If so, why?
It’s also possible I’m simply misunderstanding what you’re objecting to.
