xAI launches Grok Voice Think Fast 1.0 for voice agents

xAI launched Grok Voice Think Fast 1.0, a flagship voice model for enterprise voice agents.

The model is available via the xAI API and voice playground, and is built for multi-step phone workflows.

It supports 25+ languages and is designed to handle noisy, interruptive calls while collecting structured information.

xAI says it tops the Tau Voice Bench and is already being used in Starlink sales and support.

The release positions xAI more directly in enterprise voice automation for customer service and call handling at scale.
