New research questions multilingual LLM alignment, citing 'Language Unalignability'

A new research paper introduces the concept of "Language Unalignability," challenging the assumption that semantic structures across languages are perfectly mappable for multilingual LLMs. The authors propose a "usage-cloud framework" to formalize this, defining unalignability as the impossibility of preserving both lexical faithfulness and structural faithfulness in translations. Evidence from FLORES-200 translation failures and a case study on the Yami language suggests that current multilingual alignment objectives may inadvertently erase cultural divergence. AI

IMPACT Challenges current approaches to multilingual LLM evaluation and alignment, suggesting a need to better respect cultural divergence.
