    I trained this model using a dataset composed almost entirely of real-world photography. My goal was to achieve realistic textures and lighting, moving away from the "plastic" look of purely synthetic datasets. While this implies the model isn't technically "perfect" yet, it does a crazy good job at what it was designed for.

    Key Features & Usage:

    • No Hard Trigger Word: You generally don't need a specific trigger word to get results. However, if you want to emphasize the size, simply adding keywords like huge or big will push the model to the limit.

    • No Body Type Bias: Almost anytime traning a model like this using real data, most of the models should have a natural tendency to generate "chunky" or curvy women, this model besides shouldn't do it. If it does and you prefer a slimmer physique, simply add skinny to your prompt, and it should correct the body type without issues.

    • Wardrobe Malfunctions: Be aware: if your prompt includes "cleavage," the model has a high probability of generating an areola slip. If this isn't what you're looking for, try rolling a different seed (though personally, I consider it a feature, not a bug 👀).

    ⚠️ Current Limitations:

    • Mixed Sizes: I haven't managed to get the model to generate multiple subjects with different sizes in the same image (e.g., one small, one huge) just yet. It tends to average them out.

    • Future Updates: This is an initial version. I might release a fine-tuned v2 to fix the mixed-size issue, but honestly, I'm pretty lazy, so enjoy this version for now!

    Description

    It should be more stable and have a more natural look, now it should generate easier covered ones, it should generate big ones even if you don't add some size prompt tag in case it dosn't just add a cleavage

    no matter what i do every gen i make has naked breasts or at minimum the nipples showing through clothes, even at low strength the nipples always are there even if i say "Cover the chest", how do I make the clothes work and cover the chest properly no matter how big?
