DetectGPT: Zero-Shot Machine-Generated Text Detection using Probability Curvature

Official implementation of the experiments in the DetectGPT paper.

An interactive demo of DetectGPT can be found here.

Instructions

First, install the Python dependencies:

python3 -m venv env
source env/bin/activate
pip install -r requirements.txt

Second, run any of the scripts (or just individual commands) in paper_scripts/.

If you'd like to run the WritingPrompts experiments, you'll need to download the WritingPrompts data from here. Save the data into a directory data/writingPrompts.

Note: Intermediate results are saved in tmp_results/. If your experiment completes successfully, the results will be moved into the results/ directory.
