<Note>
  Looking for `inworld-tts-1` or `inworld-tts-1-max`? These previous-generation models were discontinued on **June 15, 2026**. Requests to them are now automatically routed to their 1.5 successors (`inworld-tts-1` → `inworld-tts-1.5-mini`, `inworld-tts-1-max` → `inworld-tts-1.5-max`). We recommend migrating to `inworld-tts-2` to improve quality and latency.
