Voice
Spoken back-and-forth in the app, and the Voice Agent Builder for phone-style agents.
Voice is a control on the Grok composer and a full Voice Agent Builder on x.ai/voice. Speech-to-speech, transcription, text-to-speech, and cloning are listed there. I have used the mic. I have not deployed a phone number from this overview.

Flagship for chat and code on the pages I opened. SpaceXAI calls it the newest model powering Grok Build.
