# GGUF Model Quantization & Usage Guide with llama.cpp

## What is GGUF and Quantization?

**GGUF** (GPT-Generated Unified Format) is an efficient model file format developed by the `llama.cpp` team that:
- Supports multiple quantization levels
- Works cross-platform
- Enables fast loading and inference

**Quantization** converts model weights to lower precision data types (e.g., 4-bit integers instead of 32-bit floats) to:
- Reduce model size
- Decrease memory usage
- Speed up inference
- (With minor accuracy trade-offs)

## Step-by-Step Guide

### 1. Prerequisites

```bash
# System updates
sudo apt update && sudo apt upgrade -y

# Dependencies
sudo apt install -y build-essential cmake python3-pip

# Clone and build llama.cpp
git clone https://github.com/ggerganov/llama.cpp
cd llama.cpp
make -j4
```

### 2. Using Quantized Models from Hugging Face

My automated quantization script produces models in this format:
```
https://huggingface.co/matrixportal/txgemma-9b-chat-GGUF/resolve/main/txgemma-9b-chat-q4_k_m.gguf
```

Download your quantized model directly:

```bash
wget https://huggingface.co/matrixportal/txgemma-9b-chat-GGUF/resolve/main/txgemma-9b-chat-q4_k_m.gguf
```

### 3. Running the Quantized Model

Basic usage:
```bash
./main -m txgemma-9b-chat-q4_k_m.gguf -p "Your prompt here" -n 128
```

Example with a creative writing prompt:
```bash
./main -m txgemma-9b-chat-q4_k_m.gguf        -p "[INST] Write a short poem about AI quantization in the style of Shakespeare [/INST]"        -n 256 -c 2048 -t 8 --temp 0.7
```

Advanced parameters:
```bash
./main -m txgemma-9b-chat-q4_k_m.gguf        -p "Question: What is the GGUF format?
Answer:"        -n 256 -c 2048 -t 8 --temp 0.7 --top-k 40 --top-p 0.9
```

### 4. Python Integration

Install the Python package:
```bash
pip install llama-cpp-python
```

Example script:
```python
from llama_cpp import Llama

# Initialize the model
llm = Llama(
    model_path="txgemma-9b-chat-q4_k_m.gguf",
    n_ctx=2048,
    n_threads=8
)

# Run inference
response = llm(
    "[INST] Explain GGUF quantization to a beginner [/INST]",
    max_tokens=256,
    temperature=0.7,
    top_p=0.9
)

print(response["choices"][0]["text"])
```

## Performance Tips

1. **Hardware Utilization**:
   - Set thread count with `-t` (typically CPU core count)
   - Compile with CUDA/OpenCL for GPU support

2. **Memory Optimization**:
   - Lower quantization (like q4_k_m) uses less RAM
   - Adjust context size with `-c` parameter

3. **Speed/Accuracy Balance**:
   - Higher bit quantization is slower but more accurate
   - Reduce randomness with `--temp 0` for consistent results

## FAQ

**Q: What quantization levels are available?**  
A: Common options include q4_0, q4_k_m, q5_0, q5_k_m, q8_0

**Q: How much performance loss occurs with q4_k_m?**  
A: Typically 2-5% accuracy reduction but 4x smaller size

**Q: How to enable GPU support?**  
A: Build with `make LLAMA_CUBLAS=1` for NVIDIA GPUs
