Elon Musk’s AI company just made it significantly cheaper to build a voice agent. xAI launched the beta version of its Voice Agent Builder on July 1, offering a no-code platform where users can create custom voice agents powered by Grok Voice in under two minutes.
The pricing is straightforward: $0.05 per minute of audio for agents, plus an additional $0.01 per minute for telephony on provisioned phone numbers.
What the Voice Agent Builder actually does
The platform supports over 25 languages and more than 80 distinct voices, with sub-second latency claims for VoIP production environments.
xAI is positioning this for production deployments across customer support, sales, and other business-critical functions. The platform includes integration with various external tools, provisioned phone numbers at no extra charge, and direct SIP connectivity for enterprises that want to plug voice agents into existing telephony infrastructure.
