SpaceXAI said Grok Voice models can now be used in LiveKit to build voice agents with full zero-data-retention support. LiveKit showed a patient-intake agent that cascades Grok STT, Grok 4.3, and Grok TTS through LiveKit Inference in a single AgentSession, with one set of credentials and billing. For developers, that is a three-string voice stack instead of a glued-together ASR, LLM, and TTS bill.

Key Takeaways

  • βœ“Grok Voice is available in LiveKit with zero-data-retention on every hop.
  • βœ“STT, Grok 4.3, and TTS cascade in one AgentSession with unified credentials and billing.
  • βœ“The reference build is a patient-intake agent for real-time, tool-using voice workflows.
