AssemblyAI Universal-3.5 Pro Realtime — the flagship streaming model, with native mid-sentence code-switching across 18 languages and conversation context carried across turns. Word-level timestamps and stable partials that are not rewritten as they arrive; speaker diarization is available on the batch model, not this streaming one.
