    Core Concept

    altF4 is a fine-tuned diffusion model engineered to produce images that balance photorealistic foundations with a distinct, energetic, and fluid art style.

    Technical Details

    • Base Model: Initialized from the UltraReal Fine-Tune checkpoint, chosen for its superior handling of photorealistic details and lighting.

    • Training Data: Fine-tuned on a proprietary dataset of 22,000+ images. The dataset was curated to emphasize motion, dynamic lighting, and strong visual flow. All images was sourced entirely from materials with licenses permissive for AI training.

    • Current Status: This is an early-stage release. Further training epochs and potential architectural refinements are planned to enhance stylistic consistency and reduce artifacts. Community testing is welcome.

    Known problems

    • Nipples sometimes appear on clothing.

    • Vagina - only more training iterations needed. In the current version, the results are not always good

    • Hardcore - will be addressed in the next version.

    Acknowledgements

    Profound thanks to the developers of UltraReal Fine-Tune for providing the high-quality foundational model that made this project possible.
