# Foundation-Sec-8B-Reasoning-Q8_0-GGUF

**This model was quantized from fdtn-ai/Foundation-Sec-8B-Reasoning to a 8-bit (Q8_0) GGUF checkpoint using llama.cpp. It retains the cybersecurity specialization of the original 8-billion-parameter model while reducing the memory footprint from approximately 16GB (BF16) to around 8.54GB (Q8_0) for inference.**

## Model Description

`fdtn-ai/Foundation-Sec-8B-Reasoning-Q8_0-GGUF` is an 8-bit quantized variant of **Foundation-Sec-8B-Reasoning** — an 8B-parameter LLaMA 3.1–based model that extends the **Foundation-Sec-8B** base model with instruction-following and reasoning capabilities. The base model was continued-pretrained on a curated corpus of cybersecurity-specific text (e.g., CVEs, threat intel reports, exploit write-ups, compliance guides). Foundation-Sec-8B-Reasoning is optimized for three core use case categories:

- **SOC Acceleration**: Automating triage, summarization, case note generation, and evidence collection.
- **Proactive Threat Defense**: Simulating attacks, prioritizing vulnerabilities, mapping TTPs, and modeling attacker behavior.
- **Engineering Enablement**: Providing security assistance, validating configurations, assessing compliance evidence, and improving security posture.

Rather than re-uploading or replicating the entire training details, please refer to the original model card for foundational architecture, training data, evaluation results, and known limitations. 

## Quantization Details

- **Quantization Scheme:** 8-bit, "Q8_0" (8-bit quantization with minimal precision loss)  
- **Toolchain:** Converted via [llama.cpp's export utilities](https://github.com/ggml-org/llama.cpp) (commit `v0.1.81` or newer) to GGUF format.
- **Resulting File Size:** ~ 8.54 GB on disk (raw GGUF blob)   
- **Runtime Footprint:** 
  - Memory: ≈ 8.54 GB of RAM when loaded on CPU with llama.cpp  
- **Format:**
  - File extension: `.gguf`  
  - Internally contains:  
    1. Metadata (architecture, tokenizer vocab, hyperparameters)  
    2. Vocabulary list (BPE tokens)  
    3. Weight tensors (for each layer and head) stored in 8-bit quantized form  
  - Compliant with LlamaCpp Python wrapper (`llama_cpp`) and C++ CLI (`llama.cpp`) inference engines  

## How to Use
[The cookbook](https://github.com/cisco-foundation-ai/cookbook) provides example use cases, code samples for adoption, and references.

### Install llama.cpp on Mac

Use Homebrew:
```bash
brew install llama-cpp
```

or install from scratch:

```bash
# Install dependencies
brew install cmake
# Clone and build llama.cpp
git clone https://github.com/ggml-org/llama.cpp.git
cd llama.cpp
make
# Add to PATH (optional)
sudo cp llama-cli /usr/local/bin/
```

### Run the Model

```bash
llama-cli -m foundation-sec-8b-reasoning-q8_0.gguf -p "CVE-2021-44228 is a remote code execution flaw in Apache Log4j2 via unsafe JNDI lookups (\"Log4Shell\").
