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
