What stands out
What its maker marketed at launch, and what people found later, each with its source.
Streaming speech-to-speech translation
Simultaneous interpretation from 70+ input languages into 13 output languages, emitting translated audio plus transcript deltas while the speaker is still talking.
Dedicated translation endpoint
Served only on v1/realtime/translations (not the general Realtime or Chat endpoints).
Notes
Language counts (70+ in / 13 out) come from press coverage of the launch post; the docs page does not list languages. Latency not specified. Google’s comparable model is gemini-3.5-live-translate-preview (June 2026).
