Researchers developed a framework separating language proficiency from cultural knowledge access in large language models across 13 locales and 80 models. The study reveals that while English outperforms local languages on culture-agnostic questions, local languages consistently show advantages for accessing culture-specific knowledge once proficiency gaps are controlled for. This finding challenges the assumption that weaker local-language LLM performance indicates weaker cultural knowledge.
