About this paper

Jiatao Li, Mao Ye, Cheng Peng, Xunjian Yin, Xiaojun Wan

Peking University researchers developed AGENT-X, a zero-shot multi-agent framework that detects AI-generated text without external thresholds, achieving an average accuracy of 86.0% for ChatGPT and 85.9% for GPT-4 by leveraging linguistic guidelines and confidence-aware aggregation.

Key insights

  • Integrating explicit linguistic theories (rhetoric, functional linguistics) provides a robust and interpretable foundation for AI-generated text detection.
  • Dynamic selection of relevant detection guidelines via a router agent, combined with specialized base agents, significantly improves adaptability and efficiency.
  • Semantic-steering confidence calibration and confidence-weighted aggregation enable truly threshold-free and reliable classification for diverse texts.
