Korean Response-Style Tuning Alters Abstention in 27B Model
Researchers post-trained a 27B Qwen model to adopt a Korean response style covering verbosity, list and markdown formatting, discourse structure and register. They then measured two behaviors the training objective never targeted, including abstention on ambiguous social questions in the KoBBQ benchmark. The study reports that style-focused alignment produced measurable side effects on these untrained behaviors.
