# 🔐 Smart Contract Security Auditor — GRPO vs Base

Side-by-side comparison of a GRPO-trained smart contract security auditor vs the base Qwen2.5-Coder-0.5B-Instruct model.

**GRPO Model**: [oxdev/security-auditor-grpo](https://huggingface.co/oxdev/security-auditor-grpo) — Qwen2 0.5B fine-tuned with Group Relative Policy Optimization on smart contract audit data.

**Training Data**: [oxdev/smart-contract-security-audit-v2](https://huggingface.co/datasets/oxdev/smart-contract-security-audit-v2) — 50,902 real audit findings from top security firms.

## Features
- 🔍 Side-by-side audit comparison (GRPO vs Base)
- 📋 Pre-loaded test cases with known vulnerabilities (reentrancy, access control, oracle manipulation, etc.)
- 📊 Automated scoring of audit output quality
- ⚡ Runs on CPU (0.5B model fits comfortably)
