Purpose

This model is intended to create fit and athletic women with more definition than the standard Krea Model.

The images shown above are example of prompts with the LoRA applied and disabled. The first image is with the Lora, the second is without the Lora

Prompting

There is no keyword to prompt it, it is best to prompt it with natural text, however most images were trained with one or more of the following words and phrases:

• fit [physique, body]

• athletic [physique, body]

• toned [physique, body, muscles ]

• fitness model

• well-defined musculature

• defined [abs, arms, biceps, back, legs, etc.]

While I attempted to make sure that it won't show nudes unless prompted with the word nude, it will tend to show more nudity if the word breast is used, than without so I marked it as intended to produce nude themes.

Training method

It was trained on 150 or so images that I originally used to train a Z-Image Turbo model, but later merged into the "Z-Image Nude Women" LORA for more diversity. However when training the same 150 images and captions. It converged pretty well by step 2700 (epoch 18), but still had a bit too much bodybuilder look, step 4500 (epoch 30) seemed to be the point where it had more variety, while still not overbaking it.

The image set contains about 30 images each of
thin women not muscular - to keep it from overfitting too much
thin and trim women
athletic women doing sports
athletic women with well defined bodies
very muscular woman

50 / 50 split nude and clothed.

Notes:

I did notice that Krea tends to revert to drawings on some photos of women working out, and if you see that start the image with either:

• A photorealistic image of

• A high resolution photorealistic image

• A magazine photoshoot

Note - The images weren't trained on the above phrases, but Krea seems to tend to more photos and less drawings if added.
