# Chain-of-Zoom Complete 4-bit Quantized Pipeline

## 📋 Model Description

Complete 4-bit quantized Chain-of-Zoom pipeline with all models

This model is part of the **Chain-of-Zoom 4-bit Quantized Pipeline** - a memory-optimized version of the original Chain-of-Zoom super-resolution framework.

## 🎯 Key Features

- **4-bit Quantization**: Uses BitsAndBytes NF4 quantization for 75% memory reduction
- **Maintained Quality**: Comparable performance to full precision models
- **Google Colab Compatible**: Runs on T4 GPU (16GB VRAM)
- **Memory Efficient**: Optimized for low-resource environments

## 📊 Quantization Details

- **Method**: BitsAndBytes NF4 4-bit quantization
- **Compute dtype**: bfloat16/float16
- **Double quantization**: Enabled
- **Memory reduction**: ~75% compared to original
- **Original memory**: ~12GB → **Quantized**: ~3GB

## 🚀 Usage

```python
# Install required packages
pip install transformers accelerate bitsandbytes torch

# Load quantized model
from transformers import BitsAndBytesConfig
import torch

# 4-bit quantization config
bnb_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_quant_type="nf4",
    bnb_4bit_use_double_quant=True,
    bnb_4bit_compute_dtype=torch.bfloat16
)
