Non-English users sometimes saw responses that were mostly in their language but still contained stray English phrases — status updates ("Filing your ticket…"), confirmations, and live-agent handoff messages that the assistant had been instructed to repeat verbatim. We've updated the AI Assistant so these phrases are now produced in the user's own response language instead of being copied in English, for a more consistent multilingual experience.In offline evaluation on previously-affected conversations, the assistant went from leaking English in every case to correctly localizing ~90% of them, with no regressions. The improvement rolls out in a phased way across model-upgrade tiers. (A small set of fixed workflow status messages follows a separate localization path and isn't covered by this fix.)
