# REVEAL_fast_2class

**REVEAL-fast-2class** is a high-speed AI-Generated Content (AIGC) detection model based on Qwen3-8B. Designed for fast, document-level or block-wise scanning, this variant bypasses the reasoning generation step (`<think>`) and outputs the classification directly, enabling significantly lower inference latency.

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 discriminates between two categories:
- **Human**: Authentic human-authored text.
- **AI**: Machine-generated text (includes both fully AI-generated content and human drafts polished by AI).

*Note: For applications requiring interpretable evidence and logical chain-of-thought analysis, please refer to our `think` variant (`REVEAL_think_2class`).*

## 🚀 How to Use

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

```bash
python fast.py \
    --model_path "bmbgsj/REVEAL_fast_2class" \
    --text "The rapid advancement of Large Language Models has ushered in an era where AI-generated content is increasingly pervasive..."
```
