GeneGPT

This directory contains code and data for GeneGPT, a tool-augmented LLM for improved access to biomedical information.

Introduction

While large language models (LLMs) have been successfully applied to various tasks, they still face challenges with hallucinations, especially for specialized knowledge. We propose GeneGPT, a novel approach to address this challenge by teaching LLMs to exploit biomedical tools, specifically NCBI Web APIs, for answering information-seeking questions. Our approach utilizes in-context learning, coupled with a novel decoding algorithm that can identify and execute API calls. Empirical results show that GeneGPT achieves state-of-the-art (SOTA) performance on eight GeneTuring tasks with an average score of 0.83, largely surpassing previous SOTA (0.44 by New Bing), biomedical LLMs such as BioGPT (0.04), and ChatGPT (0.12). Further analyses suggest that: Firstly, API demonstrations are more effective than documentations for in-context tool learning; Secondly, GeneGPT can generalize to longer chains of API calls and answer multi-hop questions; Lastly, the unique and task-specific errors made by GeneGPT provide valuable insights for future improvements. Our results underline the potential of integrating domain-specific tools with LLMs for improved access and accuracy in specialized knowledge areas.

Requirements

The code has been tested with Python 3.9.13. Please first install the required packages by:

pip install -r requirements.txt

You also need an OpenAI API key to run GeneGPT with Codex. Replace the placeholder with your key in config.py:

$ cat config.py 
API_KEY = 'YOUR_OPENAI_API_KEY'

Using GeneGPT

After setting up the environment, one can run GeneGPT on GeneTuring by:

python main.py 111111

where 111111 denotes that all Documentations (Dc.1-2) and Demonstrations (Dm.1-4) are used.

To run GeneGPT-slim, simply use:

python main.py 001001

which will only use the Dm.1 and Dm.4 for in-context learning.

Evaluating GeneGPT

One can evaluate the results by running:

python evaluate.py ${RESULT_DIRECTORY}

For example, we also put our experimental results in geneturing_results and geneturing_results. By running:

python evaluate.py geneturing_results/001001/

The user can get the evaluation results of GeneGPT-slim:
