A new study has revealed that fine-tuning large language models with benign, non-adversarial data can unexpectedly increase their susceptibility to unsafe prompts. This phenomenon, termed "safety drift," is particularly pronounced in multilingual settings, where fine-tuning in non-English languages can lead to a four-fold increase in adversarial compliance. The research highlights that safety outcomes are highly sensitive to the language used for fine-tuning and evaluation, and that assessing models solely in English provides insufficient safety assurance. To address this, the study introduces the Multilingual-Benign-Tune dataset and the SORRY-Bench-Multilingual evaluation suite to further investigate these cross-lingual safety blind spots. AI
