🔍 Chain-of-Zoom DIFFUSION (8-bit Optimized)

High-quality diffusion model optimized with 8-bit quantization for Chain-of-Zoom super-resolution. Core component for generating detailed super-resolved images.

🎯 Model Overview

This is a 8-bit quantized version of the DIFFUSION component for the Chain-of-Zoom super-resolution pipeline, specifically optimized for production deployment while maintaining exceptional quality.

⚡ Key Features

Quantization: 8-bit precision for optimal memory/quality balance
Memory Usage: 2.6GB (reduced from 5.2GB)
Memory Reduction: 50% size reduction
Quality Preservation: High quality maintained
Hardware Compatibility: Optimized for Google Colab T4 GPU (16GB)
Framework: Diffusers compatible

📊 Chain-of-Zoom Pipeline Architecture

Chain-of-Zoom achieves extreme super-resolution (8x-32x) through intelligent autoregressive scaling:

Input Image → VLM Analysis → Enhanced Prompts → Diffusion SR → Output Image
     ↑             ↓              ↓               ↓           ↑
     └─── RAM Tags ←─── LoRA Adapt ←─── Scale Chain ←─── Iterate

🔧 Component Roles:

VLM (8-bit): Context-aware prompt generation
Diffusion (8-bit): High-quality super-resolution
RAM (4-bit): Image analysis and tagging
LoRA (4-bit): Cross-component optimization

🚀 Quick Start

python

# Install requirements
pip install transformers diffusers torch accelerate bitsandbytes

# Load DIFFUSION model
from transformers import AutoModel, BitsAndBytesConfig
import torch

# Configure quantization
quantization_config = BitsAndBytesConfig(
    load_in_8bit=True,
    llm_int8_threshold=6.0
)

# Load quantized model
model = AutoModel.from_pretrained(
    "humbleakh/stable-diffusion-8bit-chain-of-zoom",
    quantization_config=quantization_config,
    device_map="auto",
    torch_dtype=torch.bfloat16
)

# Initialize pipeline
pipeline = ChainOfZoom8BitOptimal()

# Load your image
from PIL import Image
image = Image.open("low_res_image.jpg")

# Run super-resolution
results = pipeline.chain_of_zoom(image, target_scale=8)
final_image = results[-1]['image']
final_image.save("super_resolved_8x.jpg")

🎯 Applications

Photo Enhancement: Restore old or low-quality photos
