Realistic Vision XL

Realistic Vision XL (RealVisXL) is a Stable Diffusion XL-based text-to-image model focused on achieving photorealistic image generation. The model utilizes the Diffusers library and safetensors format, with the latest Version 5.0 released on December 31, 2024. It represents a sophisticated merge of multiple prominent models, including DreamShaper XL1.0, Juggernaut XL, SDVN6-RealXL, and several others, creating a powerful synthesis of their respective strengths.

The model underwent extensive training for 672,000 steps and employs a BakedVAE architecture. Version 5.0 demonstrates notable improvements in anatomy, overall model quality, and detail compared to its predecessors. The model is capable of generating both SFW and NSFW content with high fidelity.

Model Family and Variants

RealVisXL is part of a broader family of models that includes several variants and related models:

• Multiple versions (V1.0 through V5.0)
• Lightning variants for each version
• Related models like ParagonXL, NovaXL, and RealDreamXL

Each version comes with both standard and Lightning variants, with the Lightning versions optimized for faster generation times while maintaining quality. The model family demonstrates versatility across different use cases, from portrait generation to landscape creation.

Optimal Usage and Parameters

For optimal results, the model creators recommend specific parameter configurations:

Standard Version:

• DPM++ SDE Karras sampler with 30+ steps
• DPM++ 2M Karras sampler with 50+ steps
• CFG scale: 1-2.5

Lightning Variant:

• DPM++ SDE Karras/DPM++ SDE samplers
• 4-6 sampling steps
• CFG scale: 1-2

For high-resolution fixes (Hires.Fix), recommended settings include:

• Upscalers: 4x-NMKD-Superscale-SP_178000_G or 4x-UltraSharp
• Denoising strength: 0.1-0.3
• Upscale factor: 1.1-1.5
• Optional ENSD value: 31337

A suggested negative prompt for optimal results is: (worst quality, low quality, illustration, 3d, 2d, painting, cartoons, sketch), open mouth
