REVEAL_think_2class

REVEAL-think-2class 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 binary classification (<answer>...</answer>).

This model is introduced in the paper: Reasoning-Aware AIGC Detection via Alignment and Reinforcement.

🌟 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).

🚀 How to Use

To run inference, simply use the 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.

python think.py \
    --model_path "bmbgsj/REVEAL_think_2class" \
    --text "The rapid advancement of Large Language Models has ushered in an era where AI-generated content is increasingly pervasive..."
