I have a question. I started experimenting with AI a few weeks ago using Comyui and did some trials with flux models recently. However, I couldn't generate NSFW (i.e. adult) results with flux models and according to some google search results these models cannot be used for that kind of images.
Browsing though your posts, I noticed you mentioned Flux models so I was wondering how you managed to make adult images with those models. As said, I"m a newbie so I may have missed something.
Thanks in advance for any hints!

The matter is quite complex, and you can find more info for example on YT searching with terms like "NSFW AI models".
In brief, there are NSFW models and LoRA's that allow you to create that kind of content, like for example:
Thanks for your reply and the tip about LoRA.
I use models from civitai.com and with SD1.5 and SDXL models from civitai.com I have no problem with generating NSFW images but when I try using exactly the same text prompts on Flux models it doesn't work.
On the net I found following statement:
Flux models are not inherently designed for creating NSFW (Not Safe For Work) images,
However, I just found out that are workarounds by applying LoRA files like you already suggested so I will look into that. It seems there's also a security setting that needs to be changed to disable restrictions on flux models.
Anyway, I only started looking into AI image generation about 2 weeks ago so I'm still at the bottom of the learning curve
I pretty much use flux exclusively now (running locally on my machine), and I haven't had any issues producing NSFW images. However the base model (flux1-dev-fp8) is "poisoned". That is nipples etc are corrupted. There are a few ways to get around that issue.
1) Use a different flux model. fuxCapacityNSFW, fluxedUpNSFW or fluxctasy are ones I use, altho any flux model that's trained as opposed to merged has a better chance of working. The quality of the images isn't quite as good as the base model, but at least the nudity mostly works .
2) Use LoRAs. I don't like using LoRAs, as I find they subtract as much as they add. Having said that the above images use a LoRA that I made to produce the whipmarks.
3) Generate images with the base model and then upscale them with one of the other models (I use fuxCapacityNSFW) The initial image will have corruption, but the upscaling will correct it. This is the method I now use, and the above images were created using this method.

I hope this helps.
Thanks for your input Ted, it sure helps.
After reading LoyalFan's message I realized I didn't download the flux models from civitai but straight off the black-forest-labs site so that might explain why I couldn't generate nsfw images with those models.
I'll give it another try with flux models from civitai.

Thanks for your hint
You're most welcome! Something very important to keep in mind is that prompting works differently in Flux. For example, negative prompts have no use and parentheses are ignored.

Could you please elaborate on this? Is this an image-to-image method?
