Upscale and Enhance AI-generated images into photorealistic masterpieces with pure compute-driven AI workflow

Advanced AI image enhancement that eliminates artifacts, adds natural depth, improves details, and upscales with photorealistic quality for stunning, professional results.

📋 Overview

This specialized workflow prioritizes quality over speed, using an intensive multi-stage process to transform AI-generated images. Rather than quick fixes, it employs a thorough sequence of professional enhancement techniques that combine multiple state-of-the-art Stable Diffusion models with powerful computer vision to:

  • ✨ Fix AI artifacts and improve photorealism through deliberate multi-stage processing
  • 🔍 Add natural depth with realistic depth-of-field effects and subtle background blur
  • 🖼️ Preserve composition while enhancing details and correcting common AI flaws
  • 📈 Upscale by 2x or 4x with AI-powered detail preservation and enhancement

🚀 Features

  • High-Quality Focus: Optimized for maximum image quality, not processing speed
  • Multi-Stage Processing Pipeline: Uses a sophisticated sequence of model applications rather than a single-pass approach
  • AI Image Enhancement: Specifically tuned to improve AI-generated images for more photorealistic results
  • Depth-Aware Processing: Uses Depth Anything V2 to add realistic depth effects often missing in AI art
  • Intelligent Depth Blur: Applies light, natural-looking blur based on depth map for more photographic results
  • Content Safety: Automatically detects and blurs NSFW content for appropriate usage
  • Flexible Upscaling: Choose between 2x or 4x upscaling depending on your needs
  • High-Resolution Output: Upscales images while maintaining quality
  • JPEG Output: All processed images are saved in high-quality JPEG format

📥 Input/Output Options

  • Single Image: Process one image at a time (JPEG, PNG, WebP, BMP supported)

  • Output Format: All images are output as high-quality JPEGs for consistency

🖌️ Models Used

This workflow combines several powerful models to achieve stunning results:

🎨 Stable Diffusion Models

  • cyberillustrious v3.5 by Cyberdelia - Realistic detail enhancement and excellent text handling (Creator of the Illustrious-XL-v1.0: OnomaAI based on SDXL by [StabilityAI] https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0 )
  • cyberrealistic v5.7 by Cyberdelia - Upscale model
  • epicrealismNatural v4.0 by epinikion - Good hair
  • perfectdeliberate v5 by Desync - Good skin

🔍 ControlNets & Special Models

  • Depth Anything V2 - Advanced depth map generation for realistic focal effects
  • OpenPoseXL2 - Pose understanding for better human subjects
  • diffusers_xl_depth_full - Depth-based detail control and subtle background blurring
  • Face Detailer Node - Enhances facial features and details for more realistic portraits
  • Florence-2 - Used to caption images and OCR text in the images

🔧 Enhancement Tools

  • HandFineTuning_XL by Hustmox - Hand detail improvement
  • 4xRealWebPhoto_v4 by Phips - High-quality photo-realistic upscaling
  • IP-Adapter SDXL Plus - Style and composition guidance

💡 Usage Guide

  1. Upload a image
  2. Wait for the enhancement process to complete (About 3 Minutes)
  3. Download your enhanced image

⚠️ Important Limitations

  • Image Ratio: Accepts all image aspect ratios. Inputs are resized so that the longest side is 1536 px and the shorter side is scaled proportionally. No cropping.
  • Output Resolution: Final images have the longest side at either 3072 px (2×) or 6144 px (4×), with the shorter side scaled proportionally.
  • Text Processing: While the tool can process text in images, results may not always be perfect.
  • Depth Blur: The depth-based blur effect can be disabled if preferred.
