epiCRealism

The epiCRealism model represents a significant advancement in photorealistic image generation using Stable Diffusion technology. Built on the SD 1.5 base model, this final iteration of the epiCRealism family (as of October 2024) focuses on enhanced prompt understanding, improved hand rendering, and heightened overall realism compared to its predecessors.

Key Features and Capabilities

The "Natural Sin RC1 VAE" variant introduces several notable improvements, particularly in the realm of photorealistic image generation. The model incorporates a specialized VAE (Variational Autoencoder) that enhances color vibrancy, though its use remains optional. This iteration demonstrates particular strength in rendering realistic human features, as evidenced by its output quality.

The model shows remarkable versatility in handling various scenarios and lighting conditions, from indoor portraits to environmental shots. However, users should note its tendency toward NSFW content generation and relatively lower sensitivity to prompt guidance compared to other models.

Optimal Usage and Settings

For best results, the creator recommends several specific parameters:

• Clip Skip: 1
• Minimum Steps: 20+ (higher steps may be necessary for artifact correction)
• CFG Scale: 5 (higher values may compromise realism)
• Recommended Samplers: SDE or DPM-Sampler for enhanced realism
• Optimal Image Sizes: 512x768 or 768x512

The model performs best with simple prompts, avoiding excessive detail keywords such as "masterpiece" or specific facial/hand/hair details. For achieving realistic outputs, simple negative prompts like "cartoon, painting, illustration" are recommended.

Advanced Features and Integration

For enhanced results, the model can be used with several recommended external tools:

• !After Detailer for refined details
• ControlNet for improved control
• Agent Scheduler for workflow management
• Ultimate SD Upscale for superior upscaling

For high-resolution outputs, the creator specifically recommends the 4x_NMKD-Superscale-SP_178000_G upscaler with a denoising setting of 0.35 and 2x upscale factor.

The model is released under the CreativeML Open RAIL-M license with a specific addendum, ensuring proper usage rights while maintaining certain restrictions. More details can be found in the license addendum.
