MajicMIX Realistic

MajicMIX Realistic is a Stable Diffusion checkpoint model designed for generating photorealistic images, with particular strength in rendering Asian faces and features. Built upon a Stable Diffusion 1.5 base model and verified by SafeTensor, it represents version 7 in the MajicMIX model family.

Technical Specifications and Usage

The model employs specific recommended parameters for optimal results. Users should utilize Euler a or Euler samplers with 20-40 steps. For high-resolution upscaling, several options are recommended:

• ESRGAN 4x
• 4x-UltraSharp
• 8x_NMKD-Superscale_150000_G

When upscaling, users should implement:

• 2+ upscale levels
• 15+ hires steps
• Denoising strength of 0.05-0.5
• Clip skip of 2

The creator strongly advises against using face restoration features, instead recommending the adetailer tool for facial refinement. Dynamic Thresholding is suggested for CFG control, with a recommended range of 1-20.

Model Family and Evolution

The MajicMIX family includes several versions, each with distinct characteristics:

• Versions 1-6: Earlier iterations, with v5 noted as insufficiently realistic
• Version 6: Emphasized Euler and Euler a samplers
• Version 7 (Current): Enhanced realism and facial detail
• Version 7 Inpainting: Specialized for inpainting tasks
• BETTER v2 (v2.5): Focused on lighting and shadow restoration

Earlier versions utilized Lora block weighting, which made replication challenging. Newer versions have moved away from this approach to improve consistency and reproducibility.

Optimal Usage and Prompting

For best results, recommended positive prompts include:

Best quality, masterpiece, ultra high res, (photorealistic:1.4), 1girl

Negative prompts should incorporate:

• ng_deepnegative_v1_75t
• badhandv4

The model incorporates elements from several other models:

• KanPiroMix
• XSMix
• ChikMix
