LIBMoE: A Library for comprehensive benchmarking Mixture of Experts in Large Language Models

Summary

This paper introduces LIBMoE, a new library designed to help researchers study and benchmark Mixture of Experts (MoE) algorithms in large language models (LLMs). It aims to make it easier for researchers to train and evaluate these complex models efficiently.

What's the problem?

Studying large-scale MoE algorithms is challenging because they require significant computing resources, making them inaccessible to many researchers. Traditional approaches to training and evaluating these models can be complicated and time-consuming, limiting the ability of researchers to experiment and innovate.

What's the solution?

LIBMoE provides a comprehensive and modular framework that simplifies the research process for MoE algorithms. It is built on three core principles: modular design, efficient training, and comprehensive evaluation. This means that researchers can easily customize their experiments, train models more efficiently, and evaluate their performance across various tasks. The library allows for benchmarking multiple state-of-the-art MoE algorithms on different datasets, helping researchers understand how these models perform in various scenarios.

Why it matters?

This research is important because it democratizes access to advanced MoE techniques in LLMs, enabling a wider range of researchers to contribute to the field. By standardizing the training and evaluation processes, LIBMoE can accelerate progress in developing more efficient and effective AI systems, ultimately leading to better applications in natural language processing and other areas.

Abstract

Mixture of Experts (MoEs) plays an important role in the development of more efficient and effective large language models (LLMs). Due to the enormous resource requirements, studying large scale MoE algorithms remain in-accessible to many researchers. This work develops LibMoE, a comprehensive and modular framework to streamline the research, training, and evaluation of MoE algorithms. Built upon three core principles: (i) modular design, (ii) efficient training; (iii) comprehensive evaluation, LibMoE brings MoE in LLMs more accessible to a wide range of researchers by standardizing the training and evaluation pipelines. Using LibMoE, we extensively benchmarked five state-of-the-art MoE algorithms over three different LLMs and 11 datasets under the zero-shot setting. The results show that despite the unique characteristics, all MoE algorithms perform roughly similar when averaged across a wide range of tasks. With the modular design and extensive evaluation, we believe LibMoE will be invaluable for researchers to make meaningful progress towards the next generation of MoE and LLMs. Project page: https://fsoft-aic.github.io/fsoft-LibMoE.github.io.
