🔍 Chain-of-Zoom LORA (4-bit Optimized)

Specialized LoRA adapters with 4-bit quantization designed for Chain-of-Zoom pipeline fine-tuning and cross-component optimization.

🎯 Model Overview

This is a 4-bit quantized version of the LORA component for the Chain-of-Zoom super-resolution pipeline, specifically optimized for production deployment while maintaining exceptional quality.

⚡ Key Features

• Quantization: 4-bit precision for optimal memory/quality balance
• Memory Usage: 25MB (reduced from 100MB)
• Memory Reduction: 75% size reduction
• Quality Preservation: Good quality maintained
• Hardware Compatibility: Optimized for Google Colab T4 GPU (16GB)
• Framework: PEFT 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:

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

🚀 Quick Start

# Install requirements
pip install transformers diffusers torch accelerate bitsandbytes

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

# Configure quantization
quantization_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_quant_type="nf4"
)

# Load quantized model
model = AutoModel.from_pretrained(
    "humbleakh/lora-adapters-4bit-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")
