ISO27001-Expert-1.5B-GGUF

GGUF quantized versions of AYI-NEDJIMI/ISO27001-Expert-1.5B for use with Ollama, llama.cpp, LM Studio, and other GGUF-compatible inference engines.

Model Description

This is a fine-tuned Qwen2.5-1.5B-Instruct model specialized in ISO 27001 information security management. It can answer questions about ISO 27001 controls, implementation guidance, risk assessment, compliance requirements, and security best practices in both French and English.

Available Quantizations

Filename	Quant Type	Size	Description
iso27001-expert-1.5b-Q4_K_M.gguf	Q4_K_M	941 MB	Recommended — Best balance of quality and size (~33% of F16)
iso27001-expert-1.5b-Q5_K_M.gguf	Q5_K_M	1.07 GB	Higher quality, slightly larger (~38% of F16)
iso27001-expert-1.5b-Q8_0.gguf	Q8_0	1.57 GB	Near-lossless quantization (~54% of F16)

Quantization Format Details

• Q4_K_M: 4-bit quantization with k-quant medium quality. Excellent for resource-constrained environments. Minimal quality loss for most tasks.
• Q5_K_M: 5-bit quantization with k-quant medium quality. Good middle ground between Q4 and Q8.
• Q8_0: 8-bit quantization. Near-original quality with ~50% size reduction from F16.

How to Use

Ollama

Create a Modelfile:

FROM ./iso27001-expert-1.5b-Q4_K_M.gguf

TEMPLATE """<|im_start|>system
{{ .System }}<|im_end|>
<|im_start|>user
{{ .Prompt }}<|im_end|>
<|im_start|>assistant
"""

SYSTEM "You are an ISO 27001 expert assistant. You provide detailed, accurate guidance on information security management systems (ISMS), ISO 27001 controls, risk assessment, and compliance. You respond in the same language as the user's question."

PARAMETER temperature 0.7
PARAMETER top_p 0.8
PARAMETER top_k 20
PARAMETER stop "<|im_end|>"

Then run:

ollama create iso27001-expert -f Modelfile
ollama run iso27001-expert

llama.cpp

# Interactive chat
./llama-cli -m iso27001-expert-1.5b-Q4_K_M.gguf \
  -p "You are an ISO 27001 expert assistant." \
  --chat-template chatml \
  -cnv

# Server mode
./llama-server -m iso27001-expert-1.5b-Q4_K_M.gguf \
  --host 0.0.0.0 --port 8080

LM Studio

1. Download the desired GGUF file
2. Open LM Studio and load the model from your downloads
3. Select the ChatML chat template
4. Set the system prompt to: "You are an ISO 27001 expert assistant."
5. Start chatting!

Python (llama-cpp-python)

from llama_cpp import Llama

llm = Llama(model_path="iso27001-expert-1.5b-Q4_K_M.gguf", n_ctx=4096)

response = llm.create_chat_completion(
    messages=[
        {"role": "system", "content": "You are an ISO 27001 expert assistant."},
        {"role": "user", "content": "Quels sont les contrôles clés de l'Annexe A de la norme ISO 27001?"}
    ],
    temperature=0.7,
    top_p=0.8,
    top_k=20,
)
print(response["choices"][0]["message"]["content"])
