CyberRealistic XL is an open-source SDXL base model created by developer Cyberdelia, designed to provide natural, realistic, and scene-coherent image generation capabilities. It is positioned as a reliable foundation for realistic AI generation, suitable for creators, fine-tuners, and developers.
Purpose The model is primarily used to generate high-fidelity realistic images, with particular strengths in human skin texture, eye rendering, complex compositions, and natural lighting. It addresses common rendering errors in general SDXL base models, such as inconsistent anatomy, the need for extensive negative embeddings, and complex parameters, allowing users to obtain clean, balanced results with simpler prompts.
Key Capabilities
- Realistic skin texture and eye rendering: capable of generating highly realistic skin details and eye features.
- Concise prompts: descriptive natural language is sufficient; lengthy repetitive prompt structures are not needed.
- Coherent anatomy: maintains plausible human anatomy and hands.
- Diverse compositions: handles action shots and multi-subject scenes while maintaining consistency in spatial and depth perspective.
- LoRA and ControlNet compatibility: supports popular SDXL ControlNet and IP-Adapter, and can be seamlessly integrated into existing workflows.
- Built-in VAE: works out of the box, with predictable colors, reduced desaturation issues, and natural skin tones and neutral lighting.
- Optimized CFG sensitivity: maintains high quality at lower CFG scales (3-5), reducing visual noise and digital artifacts.
- Continuous evolution: v1.0 established the realistic foundation, v6.0 integrated an advanced training branch to enhance contrast, and v10.0 optimized lighting and reduced digital artifacts.
How to Use
- Load the checkpoint: download the latest CyberRealistic XL safetensors file and place it in the model directory of stable-diffusion-webui or ComfyUI.
- Keep prompts simple: write prompts in descriptive natural language, for example "A candid portrait of a woman at a coffee shop, natural light, shallow depth of field".
- Configure the sampler: set the sampler to DPM++ 2M SDE Karras, set steps to 30 or more, and set the CFG scale between 3 and 5.
- Upscale with Hires.fix: perform 1.5x upscaling, set denoising strength to 0.3-0.35, and use 4x_NickelbackFS_72000_G for optimal sharpness.
Applicable Scenarios
- Photographers and digital designers who need precise control over lighting, composition, and human anatomy.
- AI creators generating realistic portraits, cinematic lighting, and natural lighting scenes.
- LoRA trainers and organizations that need reliable output and realistic textures.
- Use with tools such as ComfyUI, Automatic1111, and Forge for professional workflows.
Limitations The materials do not provide information on model size, hardware requirements, generation speed, or specific licensing terms. Regarding commercial use licensing, it only mentions that "generated images are allowed for commercial use"; specific terms are not yet provided.
