Introduction to MarkLLM

Overview

MarkLLM is an open-source toolkit developed to facilitate the research and application of watermarking technologies within large language models (LLMs). As the use of large language models (LLMs) expands, ensuring the authenticity and origin of machine-generated text becomes critical. MarkLLM simplifies the access, understanding, and assessment of watermarking technologies, making it accessible to both researchers and the broader community.

Key Features of MarkLLM

Implementation Framework: MarkLLM provides a unified and extensible platform for the implementation of various LLM watermarking algorithms. It currently supports nine specific algorithms from two prominent families, facilitating the integration and expansion of watermarking techniques.

How to use the toolkit in your own code

Setting up the environment

python 3.9
pytorch
pip install -r requirements.txt

Tips: If you wish to utilize the EXPEdit algorithm, you will need to import for .pyx file,

run python watermark/exp_edit/cython_files/setup.py build_ext --inplace
move the generated .so file into watermark/exp_edit/cython_files/

# Generate and detect
watermarked_text = myWatermark.generate_watermarked_text(prompt)
detect_result = myWatermark.detect_watermark(watermarked_text)
unwatermarked_text = myWatermark.generate_unwatermarked_text(prompt)
detect_result = myWatermark.detect_watermark(unwatermarked_text)

Visualizing Mechanisms

Assuming you already have a pair of watermarked_text and unwatermarked_text, and you wish to visualize the differences and specifically highlight the watermark within the watermarked text using a watermarking algorithm, you can utilize the visualization tools available in the visualize/ directory.

Leveraging example scripts for evaluation

In the evaluation/examples/ directory of our repository, you will find a collection of Python scripts specifically designed for systematic and automated evaluation of various algorithms. By using these examples, you can quickly and effectively gauge the d etectability, robustness and impact on text quality of each algorithm implemented within our toolkit.

Note: To execute the scripts in evaluation/examples/, first run the following command to set the environment variables.

export PYTHONPATH="path_to_the_MarkLLM_project:$PYTHONPATH"

More user examples

Additional user examples are available in test/. To execute the scripts contained within, first run the following command to set the environment variables.

export PYTHONPATH="path_to_the_MarkLLM_project:$PYTHONPATH"

Demo jupyter notebooks

In addition to the Colab Jupyter notebook we provide (some models cannot be downloaded due to storage limits), you can also easily deploy using MarkLLM_demo.ipynb on your local machine.
