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.
