Z-Image Nude Women

Purpose

I noticed when training a few Z-Image Lora's that it quickly showed improvement in image quality and better looking breasts, specifically in the Tit fucking lora, so I decided to try to create a Lora that allowed for more variety in output as well as allowing for more varied breasts sized both natural and enhanced.

So this is an inital attempt I made to get more realistic output.

It was trained on 250 images nude women of various breast sizes for 99 epochs. It likely has way too many images, but should be a basis for when Z-Image Dev comes out. It started consistently producing much better images of a woman's breasts and nipples around epoch 10 and by epoch 50 every test image that didn't show genitalia was very good.

However I wanted to get it a lot better overall, and not just for more realistic breast, which definitely means it was way overtrained.

With my limited testing it did seem to produce more variety in women, however it will tend to produce nudes when not prompted.

Purpose

Is to generate a bit more realistic looking nude women as well as increasing the variety of output.

The main purpose is to show more natural looking breasts, genitals and nipples.

It does most of this, although it is weakest at genitals.

Prompting

This model was trained on descriptive prompts generated by JoyCaption Beta 1, with manual edits for accuracy and reducing wordiness. So descriptive prompts are best. See the images I uploaded for examples.

Trigger words

The model was not trained on a trigger word, instead using descriptive prompts to help guide the output. While there are no trigger words below are the most common tokens used in the training data.

Nude, topless and bottomless. These three token help guide the output to the appropriate lack of clothing.

Enhanced, round, perky, natural. Adding one or more of these words with breast will push the output towards the appropriate breast type.

Small, medium, large, very large. Adding one of these words will suggest the appropriate breast size. This is very finicky, but often describing body type helps.

Note: I also had tiny and flat chested, but for the most part Z-Image seemed to ignore this.

Skinny, thin, slender, fit. Describes the body type, and tends to aid in making the breast sized more accurate. Often you will have to add the word physique to this, buti it's not consistent.

Legs spread, spread wide. While I first attempted to use anatomical and descriptive terms for genitalia, but it seemed to make things worse. So I removed for the most part all references and just said legs spread and spread wide to show the vagina.
