MGTBench

MGTBench provides the reference implementations of different machine-generated text (MGT) detection methods. It is still under continuous development and we will include more detection methods as well as analysis tools in the future.

Supported Methods

Currently, we support the following methods (continuous updating):

• Metric-based methods:
  • Log-Likelihood [Ref];
  • Rank [Ref];
  • Log-Rank [Ref];
  • Entropy [Ref];
  • GLTR Test 2 Features (Rank Counting) [Ref];
  • DetectGPT [Ref];
  • LRR [Ref];
  • NPR [Ref];
• Model-based methods:
  • OpenAI Detector [Ref];
  • ChatGPT Detector [Ref];
  • ConDA [Ref] [Model Weights];
  • GPTZero [Ref];
  • LM Detector [Ref];

Supported Datasets

• Essay;
• WP;
• Reuters;

Note that our datasets are constructed based on Verma et al., you can download them from Google Drive.

Installation

git clone https://github.com/xinleihe/MGTBench.git;
cd MGTBench;
conda env create -f environment.yml;
conda activate MGTBench;

Usage

To run the benchmark on the Essay dataset:

# Distinguish Human vs. Claude:
python benchmark.py --dataset Essay --detectLLM Claude --method Log-Likelihood

# Text attribution:
python attribution_benchmark.py --dataset Essay

Note that you can also specify your own datasets on dataset_loader.py.
