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

# 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
)
