NSFW Female Nudity - NaturalBeauty FLUX.2 [klein]

NaturalBeauty FLUX.2 Nudity is a photorealistic FLUX.2 [klein] 9B LoRA for creating nude and topless images of beautiful women.

• To trigger the LoRA, add naked or topless to your prompt. (bottomlessalso works!)

• You can also add breasts visible, nipples visible, and / or pussy visible to accentuate things further.

NaturalBeauty enables FLUX.2 [klein] 9B to reliably generate naked and semi-naked photos with correct anatomy, and with a more photorealistic look than the default model alone.

This LoRA is the result of a two-year project to tag 29k+ images from a diverse dataset. No watermarks, no tattoos; just beautiful images of beautiful women.

Tagging

NaturalBeauty FLUX.2 Nudity can do more than just nudity! In addition to naked and topless, try adding any of the following extra details for more control:
