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
