Our blogpost: https://sites.google.com/berkeley.edu/mast/ This repository contains the code and the data for the paper "Why Do Multi-Agent Systems Fail?" [https://arxiv.org/pdf/2503.13657](https://arxiv.org/pdf/2503.13657v2) In this paper, we present the first comprehensive study of MAS challenges: MAST (Multi-Agent Systems Failure Taxonomy).   ## News! We just released our dataset with over 1K annotated MAS traces [https://arxiv.org/pdf/2503.13657v2](https://huggingface.co/datasets/mcemri/MAD) For LLM-as-a-Judge annotated traces: ``` from huggingface_hub import hf_hub_download import pandas as pd import json REPO_ID = "mcemri/MAD" FILENAME = "MAD_full_dataset.json" file_path = hf_hub_download(repo_id=REPO_ID, filename=FILENAME, repo_type="dataset") with open(file_path, "r") as f: data = json.load(f) print(f"Loaded {len(data)} records (full dataset).") ``` For human annotated traces: ``` FILENAME = "MAD_human_labelled_dataset.json" file_path = hf_hub_download(repo_id=REPO_ID, filename=FILENAME, repo_type="dataset") with open(file_path, "r") as f: data = json.load(f) print(f"Loaded {len(data)} records (human labelled).") ``` If you find this work useful, please cite it as follows: ```bibtex @article{cemri2025multi, title={Why Do Multi-Agent LLM Systems Fail?}, author={Cemri, Mert and Pan, Melissa Z and Yang, Shuyi and Agrawal, Lakshya A and Chopra, Bhavya and Tiwari, Rishabh and Keutzer, Kurt and Parameswaran, Aditya and Klein, Dan and Ramchandran, Kannan and others}, journal={arXiv preprint arXiv:2503.13657}, year={2025} } ```
