Qwen3 4B Customer Support - GGUF

This repository contains GGUF quantized versions of ragib01/Qwen3-4B-customer-support for efficient inference with llama.cpp and compatible tools.

Model Description

A fine-tuned Qwen3-4B model optimized for customer support tasks, converted to GGUF format for efficient CPU and GPU inference.

Available Quantization Formats

Filename	Quant Method	Size	Description	Use Case
Qwen3-4B-customer-support-f16.gguf	f16	~8GB	Full 16-bit precision	Best quality, requires more RAM
Qwen3-4B-customer-support-Q8_0.gguf	Q8_0	~4.5GB	8-bit quantization	High quality, good balance
Qwen3-4B-customer-support-Q6_K.gguf	Q6_K	~3.5GB	6-bit quantization	Good quality, smaller size
Qwen3-4B-customer-support-Q5_K_M.gguf	Q5_K_M	~3GB	5-bit medium	Balanced quality/size
Qwen3-4B-customer-support-Q4_K_M.gguf	Q4_K_M	~2.5GB	4-bit medium	Recommended - best balance
Qwen3-4B-customer-support-Q4_K_S.gguf	Q4_K_S	~2.3GB	4-bit small	Smaller, slightly lower quality
Qwen3-4B-customer-support-Q3_K_M.gguf	Q3_K_M	~2GB	3-bit medium	Very small, decent quality
Qwen3-4B-customer-support-Q2_K.gguf	Q2_K	~1.5GB	2-bit	Smallest, lower quality

Recommendation: Start with Qwen3-4B-customer-support-Q4_K_M.gguf for the best balance of quality and size.

Usage

LM Studio

1. Open LM Studio
2. Go to the "Search" tab
3. Search for ragib01/Qwen3-4B-customer-support
4. Download your preferred quantization
5. Load and start chatting!

llama.cpp (Command Line)

# Download a model
huggingface-cli download ragib01/Qwen3-4B-customer-support-gguf Qwen3-4B-customer-support-Q4_K_M.gguf --local-dir ./models

# Run inference
./llama-cli -m ./models/Qwen3-4B-customer-support-Q4_K_M.gguf -p "How do I track my order?" -n 256

Python (llama-cpp-python)

from llama_cpp import Llama

# Load model
llm = Llama(
    model_path="./models/Qwen3-4B-customer-support-Q4_K_M.gguf",
    n_ctx=2048,
    n_threads=8,
    n_gpu_layers=35  # Adjust based on your GPU
)

# Generate response
output = llm(
    "How do I track my order?",
    max_tokens=256,
    temperature=0.7,
    top_p=0.9,
)

print(output['choices'][0]['text'])

Ollama

# Create a Modelfile
cat > Modelfile << EOF
FROM ./Qwen3-4B-customer-support-Q4_K_M.gguf
PARAMETER temperature 0.7
PARAMETER top_p 0.9
EOF

# Create the model
ollama create qwen3-customer-support -f Modelfile

# Run it
ollama run qwen3-customer-support "How do I track my order?"

Prompt Format

This model uses the Qwen chat format:

<|im_start|>system
You are a helpful customer support assistant.<|im_end|>
<|im_start|>user
How do I track my order?<|im_end|>
<|im_start|>assistant

Performance Notes

• CPU: Q4_K_M works well on modern CPUs with 8GB+ RAM
• GPU: Use higher quantizations (Q6_K, Q8_0) if you have VRAM available
• Mobile: Q3_K_M or Q2_K for resource-constrained devices

Original Model

This is a quantized version of unsloth/Qwen3-4B-Instruct-2507.
