quantizing-models-bitsandbytes
Quantizes LLMs to 8-bit or 4-bit for 50-75% memory reduction with minimal accuracy loss. Use when GPU memory is limited, need to fit larger models, or want faster inference. Supports INT8, NF4, FP4 formats, QLoRA training, and 8-bit optimizers. Works with HuggingFace Transformers.

# bitsandbytes - LLM Quantization
## Quick start
bitsandbytes reduces LLM memory by 50% (8-bit) or 75% (4-bit) with <1% accuracy loss.
**Installation**:
```bash
pip install bitsandbytes transformers accelerate
```
**8-bit quantization** (50% memory reduction):
```python
from transformers import AutoModelForCausalLM, BitsAndBytesConfig
