GlotEval: A Test Suite for Massively Multilingual Evaluation of Large Language Models
This addresses the challenge for academia and industry in assessing LLM performance in multilingual and lower-resource scenarios, which are often overlooked by existing English-centric frameworks.
The paper tackles the problem of evaluating large language models (LLMs) in diverse linguistic environments, especially low-resource languages, by introducing GlotEval, a lightweight framework for massively multilingual evaluation across seven key tasks spanning dozens to hundreds of languages, enabling precise diagnosis of model strengths and weaknesses.
Large language models (LLMs) are advancing at an unprecedented pace globally, with regions increasingly adopting these models for applications in their primary language. Evaluation of these models in diverse linguistic environments, especially in low-resource languages, has become a major challenge for academia and industry. Existing evaluation frameworks are disproportionately focused on English and a handful of high-resource languages, thereby overlooking the realistic performance of LLMs in multilingual and lower-resource scenarios. To address this gap, we introduce GlotEval, a lightweight framework designed for massively multilingual evaluation. Supporting seven key tasks (machine translation, text classification, summarization, open-ended generation, reading comprehension, sequence labeling, and intrinsic evaluation), spanning over dozens to hundreds of languages, GlotEval highlights consistent multilingual benchmarking, language-specific prompt templates, and non-English-centric machine translation. This enables a precise diagnosis of model strengths and weaknesses in diverse linguistic contexts. A multilingual translation case study demonstrates GlotEval's applicability for multilingual and language-specific evaluations.
