arXiv:2606.15643v1 Announce Type: new Abstract: Multilingual benchmarks are central to evaluating large language models (LLMs) across languages, but they suffer from three issues: exhaustive evaluation scales linearly with the number of languages, automatic translation introduces errors that are easily missed at scale, and some items conflate general and culture-specific knowledge. We address all three with a unified statistical framework, Multilingual-IRT, which extends Item Response Theory with per-language difficulty deviations, split discriminability separating content from language effect
The proliferation of advanced LLMs and their deployment across diverse linguistic contexts necessitates more robust and efficient evaluation methods to ensure reliability and trust.
This development offers a standardized and more accurate way to evaluate multilingual LLMs, reducing bias and improving cross-cultural applicability, which is critical for global AI adoption and trust.
Current fragmented and often flawed multilingual evaluation methods can be replaced or significantly augmented by a unified statistical framework that accounts for language-specific nuances and content effects.

More accurate and efficient evaluation of multilingual LLMs becomes possible.
Improved LLM performance in non-English languages and culturally diverse contexts accelerates global AI adoption.
Increased global competition in AI development as language barriers to model efficacy are better understood and addressed.
