Recently, there has been a rapid advancement in research on Large Language
Models (LLMs), resulting in significant progress in several Natural Language
Processing (NLP) tasks. Consequently, there has been a surge in LLM evaluation
research to comprehend the models' capabilities and limitations. However, much
of this research has been confined to the English language, leaving LLM
building and evaluation for non-English languages relatively unexplored. There
has been an introduction of several new LLMs, necessitating their evaluation on
non-English languages. This study aims to expand our MEGA benchmarking suite by
including six new datasets to form the MEGAVERSE benchmark. The benchmark
comprises 22 datasets covering 81 languages, including low-resource African
languages. We evaluate several state-of-the-art LLMs like GPT-3.5-Turbo, GPT4,
PaLM2, and Llama2 on the MEGAVERSE datasets. Additionally, we include two
multimodal datasets in the benchmark and assess the performance of the
LLaVa-v1.5 model. Our experiments suggest that GPT4 and PaLM2 outperform the
Llama models on various tasks, notably on low-resource languages, with GPT4
outperforming PaLM2 on more datasets than vice versa. However, issues such as
data contamination must be addressed to obtain an accurate assessment of LLM
performance on non-English languages.
