Lizzy 7B GGUF Quantized Models

Quantized GGUF models for efficient CPU/GPU inference

📊 Model Variants • 🚀 Quick Start • 📚 Documentation

Overview

This repository contains GGUF-quantized versions of the Lizzy 7B, a reasoning-enhanced language model from Flower Labs with British knowledge and behavior enhancements.

Model Variants

Quantization	File Size	Quality Retention	Recommended Use Case
Q5_K_M ⭐	4.8 GB	95%	Best balance of quality and size
Q4_K_M	4.2 GB	92%	Resource-constrained environments
Q8_0	7.2 GB	99%	Near-lossless compression
Q6_K	5.6 GB	97%	Between Q5 and Q8
f16	13.6 GB	100%	Maximum quality, benchmarking

Quick Start

Using llama.cpp (Recommended)

# Clone llama.cpp with Lizzy support
git clone https://github.com/relogu/llama.cpp.git
cd llama.cpp
git checkout lorenzo-dev

# Build with CUDA support
make LLAMA_CUDA=1

# Run inference with recommended Q5_K_M quantization
./main -m lizzy-7b-Q5_K_M.gguf \
       -p "What is the capital of England?" \
       -n 128 \
       --temp 0.6 \
       --top-p 0.95 \
       -ngl 32  # Offload all layers to GPU

Using Python (llama-cpp-python)

from llama_cpp import Llama

# Load model with GPU offload
llm = Llama(
    model_path="lizzy-7b-Q5_K_M.gguf",
    n_ctx=65536,  # Full context
    n_gpu_layers=32,  # Offload to GPU
    n_threads=8,
)

# Generate with reasoning
response = llm(
    "Explain why British people queue so much.",
    max_tokens=512,
    temperature=0.6,
    top_p=0.95,
)

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

Using Ollama

# Create Modelfile
cat > Modelfile << EOF
FROM ./lizzy-7b-Q5_K_M.gguf
PARAMETER temperature 0.6
PARAMETER top_p 0.95
PARAMETER num_ctx 65536
EOF

# Create and run
ollama create lizzy -f Modelfile
ollama run lizzy "What's the best way to make tea?"

Usage with llama.cpp

Basic Inference

./main -m lizzy-7b-Q5_K_M.gguf \
       -p "User: Hello, assistant!\nAssistant:" \
       -n 256 \
       --temp 0.6 \
       --top-p 0.95 \
       -ngl 32

Chat Mode

./chat -m lizzy-7b-Q5_K_M.gguf \
       -ngl 32 \
       --temp 0.6 \
       --top-p 0.95

Server Mode (API)

./server -m lizzy-7b-Q5_K_M.gguf \
         -ngl 32 \
         --port 8080 \
         --host 0.0.0.0

Then access at http://localhost:8080 or use the API:

curl http://localhost:8080/completion \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Why do British people say sorry so often?",
    "n_predict": 256,
    "temperature": 0.6,
    "top_p": 0.95
  }'

Reasoning Behavior

Lizzy 7B is a reasoning model that uses thinking tokens. You'll see output like:

> Let me think about this question about British culture...
> The user is asking about queuing behavior...
> I should explain the cultural significance...

British people queue because it reflects core cultural values of fairness and order...

This is expected behavior - the > prefix indicates the model's reasoning process before providing the final answer.

Documentation

The following sections provide comprehensive documentation for using Lizzy 7B GGUF models.

Model Comparison

When to Use GGUF vs. Original Format

Use GGUF when:

• ✅ You need CPU inference
• ✅ You want flexible GPU offloading
• ✅ You need smaller model size
• ✅ You're using llama.cpp ecosystem
• ✅ You want fast loading times

Use original Safetensors when:

• ✅ You need full precision (BF16)
• ✅ You're using transformers/vLLM
• ✅ You need tensor parallelism
• ✅ You're fine-tuning the model
