Promptolution

Promptolution is a library that provides a modular and extensible framework for implementing prompt tuning experiments. It offers a user-friendly interface to assemble the core components for various prompt optimization tasks.

In addition, this repository contains our experiments for the paper "Towards Cost-Effective Prompt Tuning: Evaluating the Effects of Model Size, Model Family and Task Descriptions in EvoPrompt".

This project was developed by Timo Heiß, Moritz Schlager and Tom Zehle.

Installation

Use pip to install our library:

pip install promptolution

Alternatively, clone the repository, run

poetry install

to install the necessary dependencies. You might need to install pipx and poetry first.

Core Components

• Task: Encapsulates initial prompts, dataset features, targets, and evaluation methods.
• Predictor: Implements the prediction logic, interfacing between the Task and LLM components.
• LLM: Unifies the process of obtaining responses from language models, whether locally hosted or accessed via API.
• Optimizer: Implements prompt optimization algorithms, utilizing the other components during the optimization process.
• Exemplar Selectors: Implements algorithms for the search of few shot examples that are added to the prompt.

Key Features

• Modular and object-oriented design
• Extensible architecture
• Easy-to-use interface for assembling experiments
• Parallelized LLM requests for improved efficiency
• Integration with langchain for standardized LLM API calls
• Detailed logging and callback system for optimization analysis

Getting Started

Take a look at our getting started notebook: getting_started.py

Reproduce our Experiments

We provide scripts and configs for all our experiments. Run experiments based on config via:

poetry run python scripts/experiment_runs.py --experiment "configs/<my_experiment>.ini"

where <my_experiment>.ini is a config based on our templates.

This project was developed for seminar "AutoML in the age of large pre-trained models" at LMU Munich.
