# REVEAL_think_3class

**REVEAL-think-3class** is a reasoning-driven AI-Generated Content (AIGC) detection model based on Qwen3-8B. It uses a **Think-then-Answer** paradigm, generating a transparent reasoning chain (`<think>...</think>`) before outputting the final fine-grained classification (`<answer>...</answer>`).

This model is introduced in the paper: **[Reasoning-Aware AIGC Detection via Alignment and Reinforcement](https://arxiv.org/abs/2604.19172)**.

📚 **Associated Dataset:** [AIGC-text-bank](https://huggingface.co/datasets/bmbgsj/AIGC-text-bank)

## 🌟 Model Overview

This model performs fine-grained detection, discriminating between three categories:
- **Human**: Authentic human-authored text.
- **AI-Native**: Fully machine-generated text.
- **AI-Polish**: Human-authored text refined by AI to improve fluency and style while preserving original semantics.

## 🚀 How to Use

To run inference, simply use the [`think.py`](https://github.com/microsoft/AnthropomorphicIntelligence/blob/main/REVEAL/inference/think.py) script provided in our GitHub repository. It handles prompt formatting, `vLLM` acceleration, and automatically extracts the final prediction along with fine-grained confidence scores.

```bash
python think.py \
    --model_path "bmbgsj/REVEAL_think_3class" \
    --text "The rapid advancement of Large Language Models has ushered in an era where AI-generated content is increasingly pervasive..."
```
