Personality Traits in Large Language Models

This project contains all the code necessary to verify the results of the paper > Serapio-García, G., Safdari, M., Crepy, C., Sun, L., Fitz, S., Romero, P., > Abdulhai, M., Faust, A., & Matarić, M. "Personality Traits in Large Language > Models." ArXiv.org. https://doi.org/10.48550/arXiv.2307.00184

Getting Started / Installation

Most of the code needed to reproduce the results of the paper are shared here in the form of Jupyter notebooks. The main notebooks and requirements for running the paper's psychometric and statistical analyses are located in analysis.

Inference scripts and requirements for collecting psychometric test and downstream task data from HuggingFace and OpenAI models are located in inference_scripts.

The main custom dependency of this project is the PsyBORGS psychometric test administration framework (https://github.com/google-research/google-research/tree/master/psyborgs). This repo comes with its own version of the PsyBORGS code, but if a more up-to-date version is needed, it can be downloaded from the link above. PsyBORGS-related package dependencies are specified in the requirements.txt file in its root directory. For any other dependencies, they are pip installed in the notebooks themselves.

Data

All the test admininistration sessions - which are input for most of the experiments in the paper - are stored in the admin_sessions/ directory. Some of the data used for visualization is stored in the figures_data/ directory. All other data are linked in the main paper and can be found on Google's open source GCP repository: (https://storage.googleapis.com/personality_in_llms/index.html).
