## What This Model Does

Granite 20B Code SecureCode generates security-aware code by teaching the model to recognize vulnerability patterns and produce secure implementations. Every training example includes:

- **Real-world incident grounding** — Tied to documented CVEs and breach reports
- **Vulnerable + secure implementations** — Side-by-side comparison
- **Attack demonstrations** — Concrete exploit code
- **Defense-in-depth guidance** — SIEM rules, logging, monitoring, infrastructure hardening

## Quick Start

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

base_model = AutoModelForCausalLM.from_pretrained(
    "ibm-granite/granite-20b-code-instruct-8k",
    device_map="auto",
    load_in_4bit=True
)
model = PeftModel.from_pretrained(base_model, "scthornton/granite-20b-code-securecode")
tokenizer = AutoTokenizer.from_pretrained("scthornton/granite-20b-code-securecode")

prompt = "Write a secure JWT authentication handler in Python with proper token validation"
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=512, temperature=0.7)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```
