🤖 AI Summary
Existing multilingual benchmarks primarily target fundamental language understanding tasks, failing to enable fair cross-lingual evaluation of large language models (LLMs) on advanced capabilities—such as instruction following, reasoning, long-context comprehension, and code generation.
Method: We introduce MLMA, the first multilingual benchmark covering 17 languages and explicitly designed to assess these four core competencies. MLMA features a novel tripartite native-speaker collaborative annotation protocol to systematically model semantic shifts introduced by translation, alongside multidimensional task design and rigorous bias-mitigation procedures.
Contribution/Results: Empirical evaluation reveals substantial, persistent cross-lingual performance gaps across mainstream LLMs—gaps that cannot be closed merely through model scaling. MLMA is publicly released to serve as a standardized, capability-oriented evaluation framework for multilingual LLMs.
📝 Abstract
Previous multilingual benchmarks focus primarily on simple understanding tasks, but for large language models(LLMs), we emphasize proficiency in instruction following, reasoning, long context understanding, code generation, and so on. However, measuring these advanced capabilities across languages is underexplored. To address the disparity, we introduce BenchMAX, a multi-way multilingual evaluation benchmark that allows for fair comparisons of these important abilities across languages. To maintain high quality, three distinct native-speaking annotators independently annotate each sample within all tasks after the data was machine-translated from English into 16 other languages. Additionally, we present a novel translation challenge stemming from dataset construction. Extensive experiments on BenchMAX reveal varying effectiveness of core capabilities across languages, highlighting performance gaps that cannot be bridged by simply scaling up model size. BenchMAX serves as a comprehensive multilingual evaluation platform, providing a promising test bed to promote the development of multilingual language models. The dataset and code are publicly accessible.
