Introduction

PromptBench is a Pytorch-based Python package for Evaluation of Large Language Models (LLMs). It provides user-friendly APIs for researchers to conduct evaluation on LLMs. Check the technical report: https://arxiv.org/abs/2312.07910.

What does promptbench currently provide?

1. Quick model performance assessment: We offer a user-friendly interface that allows for quick model building, dataset loading, and evaluation of model performance.
2. Prompt Engineering: We implemented several prompt engineering methods. For example: Few-shot Chain-of-Thought [1], Emotion Prompt [2], Expert Prompting [3] and so on.
3. Evaluating adversarial prompts: promptbench integrated prompt attacks [4], enabling researchers to simulate black-box adversarial prompt attacks on models and evaluate their robustness (see details here).
4. Dynamic evaluation to mitigate potential test data contamination: we integrated the dynamic evaluation framework DyVal [5], which generates evaluation samples on-the-fly with controlled complexity.
5. Efficient multi-prompt evaluation: We integrated the efficient multi-prompt evaluation method PromptEval [8]. This method uses the performance of LLMs on a small amount of data to build an IRT-like model. This model is then used to predict the performance of LLMs on unseen data. Tests on MMLU, BBH, and LMentry show that this method requires sampling only 5% of the data to reduce the error between estimated and actual performance to around 2%.

Installation

Install via pip

We provide a Python package promptbench for users who want to start evaluation quickly. Simply run:

pip install promptbench

Note that the pip installation could be behind the recent updates. So, if you want to use the latest features or develop based on our code, you should install via GitHub.

Install via GitHub

First, clone the repo:

git clone git@github.com:microsoft/promptbench.git

Then,

cd promptbench

To install the required packages, you can create a conda environment:

conda create --name promptbench python=3.9
conda activate promptbench

then use pip to install required packages:

pip install -r requirements.txt

Note that this only installed basic python packages. For Prompt Attacks, you will also need to install TextAttack.

Usage

promptbench is easy to use and extend. Going through the examples below will help you get familiar with promptbench for quick use, evaluate existing datasets and LLMs, or create your own datasets and models.

Please see Installation to install promptbench first.

If promptbench is installed via pip, you can simply do:

import promptbench as pb

If you installed promptbench from git and want to use it in other projects:

import sys

# Add the directory of promptbench to the Python path
sys.path.append('/home/xxx/promptbench')

# Now you can import promptbench by name
import promptbench as pb

We provide tutorials for:

1. evaluate models on existing benchmarks: please refer to the examples/basic.ipynb for constructing your evaluation pipeline. For a multi-modal evaluation pipeline, please refer to examples/multimodal.ipynb
2. test the effects of different prompting techniques:
3. examine the robustness for prompt attacks, please refer to examples/prompt_attack.ipynb to construct the attacks.
4. use DyVal for evaluation: please refer to examples/dyval.ipynb to construct DyVal datasets.
5. efficient multi-prompt evaluation using PromptEval: please refer to examples/efficient_multi_prompt_eval.ipynb
