Ultra-Real - Lora For Klein 9b (V2 is out)
New AI model reduces plastic look in portraits with realistic skin pores and lighting preservation.
Independent AI developer Vizsumit has launched Ultra-Real Klein 9b V2, a significant update to their popular LoRA (Low-Rank Adaptation) model for Stable Diffusion image generation. The model specifically addresses one of the most persistent complaints about AI-generated portraits: the unnaturally smooth, plastic-like appearance of skin. Version 2 builds on its predecessor by generating more nuanced and natural skin textures, including realistic pores and subtle variations, while crucially preserving the subject's original skin tone and scene lighting—issues that plagued the more heavy-handed V1.
Technically, this LoRA acts as a fine-tuned adapter for base models like SD 1.5 or SDXL, specializing in photorealism for close-up and medium shots. Beyond new image creation, Vizsumit highlights its utility for practical restoration work; the model can effectively upscale low-resolution or old photographs by intelligently adding plausible, high-fidelity skin detail. The tool is available for free download on the Civitai platform, accompanied by ready-to-use workflows for the ComfyUI interface, lowering the barrier for both hobbyists and professionals seeking more lifelike AI imagery.
- V2 reduces the 'plastic' AI look by adding natural skin texture and pores.
- Improves on V1 by better preserving original skin tone and lighting, avoiding overdone details.
- Designed for portraits but also effective for upscaling and restoring old, low-resolution photos.
Why It Matters
Moves AI-generated portraits closer to true photorealism, benefiting digital artists, photographers, and restoration projects.
