Jack: The Secure Code Agent (Llama-3 8B)

**Jack** is a specialized fine-tune of Llama-3 8B, engineered to detect and fix security vulnerabilities in Python code. It acts as an automated security auditor, taking insecure code as input and outputting a hardened, secure version.

## Key Metrics
| Metric | Score | Description |
| :--- | :--- | :--- |
| **Bandit Pass Rate** | **88.0%** | Percentage of fixes that pass the Bandit static analysis security tool. |
| **BLEU Score** | **69.27** | High structural similarity to human-expert security patches. |

## Quick Start
You can use this model directly via the Hugging Face Inference API or load it locally.

### Inference API (Serverless)
```python
import requests

API_URL = "[https://api-inference.huggingface.co/models/oke39/llama3-8b-secure-code](https://api-inference.huggingface.co/models/oke39/llama3-8b-secure-code)"
headers = {"Authorization": "Bearer YOUR_HF_TOKEN"}

payload = {
    "inputs": """<|begin_of_text|><|start_header_id|>system<|end_header_id|>

You are Jack, a Secure Code Agent. Fix the security vulnerability in the provided code.<|eot_id|><|start_header_id|>user<|end_header_id|>

def login(username, password):
    # Vulnerable SQL Injection
    query = "SELECT * FROM users WHERE username = '" + username + "' AND password = '" + password + "'"
    cursor.execute(query)<|eot_id|><|start_header_id|>assistant<|end_header_id|>
"""
}

response = requests.post(API_URL, headers=headers, json=payload)
print(response.json())
```
