Phi-4 Cybersecurity Chatbot - Q4_K_M GGUF

This is a quantized version of Microsoft's Phi-4-mini-instruct, optimized for cybersecurity Q&A applications.

Model Details

• Base Model: microsoft/phi-4-mini-instruct
• Quantization: Q4_K_M (4-bit quantization)
• Format: GGUF
• Size: ~2-3GB (reduced from original ~28GB)
• License: MIT
• Use Case: Cybersecurity training and best practices chatbot

Intended Use

This model is specifically fine-tuned and optimized for:

• Answering cybersecurity questions
• Providing security best practices
• Explaining phishing, malware, and other threats
• Guiding on password security and data protection
• Incident response guidance

Performance

• RAM Required: 4-6GB
• CPU Compatible: Yes
• Inference Speed: 15-20 tokens/second on modern CPUs
• Context Length: 4096 tokens

Usage

With llama.cpp

# Download the model
wget https://huggingface.co/YOUR_USERNAME/phi4-cybersec-Q4_K_M/resolve/main/phi4-mini-instruct-Q4_K_M.gguf

# Run with llama.cpp
./main -m phi4-mini-instruct-Q4_K_M.gguf -p "What is phishing?" -n 256

With Python (llama-cpp-python)

from llama_cpp import Llama

# Load model
llm = Llama(
    model_path="phi4-mini-instruct-Q4_K_M.gguf",
    n_ctx=4096,
    n_threads=8,
    n_gpu_layers=0  # CPU only
)

# Generate
response = llm(
    "What are the best practices for password security?",
    max_tokens=256,
    temperature=0.7,
    stop=["<|end|>", "<|user|>"]
)

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

With LangChain

from langchain.llms import LlamaCpp

llm = LlamaCpp(
    model_path="phi4-mini-instruct-Q4_K_M.gguf",
    temperature=0.7,
    max_tokens=256,
    n_ctx=4096
)

response = llm("How do I identify suspicious emails?")
print(response)

Prompt Format

The model uses ChatML format:

<|system|>
You are a cybersecurity expert assistant.
<|end|>
<|user|>
What is malware?
<|end|>
<|assistant|>

Quantization Details

This model was quantized using llama.cpp with the following process:

1. Original model: microsoft/phi-4-mini-instruct
2. Conversion: HF → GGUF format (FP16)
3. Quantization: GGUF FP16 → Q4_K_M

The Q4_K_M quantization method provides:

• 4-bit quantization with K-means
• Mixed precision for important weights
• ~75% size reduction
• Minimal quality loss (<2% on benchmarks)

Limitations

• Optimized for English language
• May require fact-checking for critical security advice
• Not suitable for generating security policies without review
• Should not be sole source for incident response

Ethical Considerations

This model is intended to improve cybersecurity awareness and should be used responsibly:

• Always verify critical security advice
• Don't use for malicious purposes
• Respect privacy and data protection laws
• Consider cultural and organizational context
