AI Fraud Detection

AI fraud detection combines ML models with LLM reasoning for better accuracy.

python
from openai import OpenAI
client = OpenAI()
def assess_transaction_risk(transaction: dict) -> dict:
    prompt = f"Assess fraud risk for: {transaction}"
    r = client.chat.completions.create(
        model="gpt-4o-mini",
        messages=[{"role":"system","content":"You are a fraud detection expert."},{"role":"user","content":prompt}]
    )
    return {"risk_assessment": r.choices[0].message.content}

Integrate with transaction monitoring, real-time scoring.
