This repository is the codebase for paper GPT-Sentinel: Distinguishing Human and ChatGPT Generating Content.

1. We collect and publish OpenGPTText - a high quality dataset with approximately 30,000 text sample rephrased by gpt-3.5-turbo (ChatGPT).
2. We construct two detectors with different architectures - the RoBERTa-Sentinel and T5-Sentinel.
3. T5-Sentinel shows SOTA performance (98% accuracy) on OpenGPTText dataset
