• Changed the default Inworld TTS model from inworld-tts-1.5-max to inworld-tts-2 (Realtime TTS-2) across InworldHttpTTSService, InworldTTSService, and the InworldRealtimeLLMService cascade. Existing users can pin the prior model explicitly via the model/tts_model argument; both inworld-tts-1.5-max and inworld-tts-1.5-mini remain valid model IDs.
