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.

📚 Associated Dataset: 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 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..."
