Update Summary

Introducing the Voice Agent Builder in beta for Grok Voice. It lets teams create production voice agents with telephony, knowledge retrieval, tools, guardrails, MCPs, and observability in about two minutes.

Update Details

Security

  • Guardrails can restrict unsafe behavior, such as reading back card numbers or discussing off-script topics.

New Features

  • No-code Voice Agent Builder for configuring production voice agents.
  • Built-in telephony, knowledge retrieval, tools, guardrails, MCPs, and observability.
  • Support for bringing existing phone numbers over SIP or connecting a custom client over WebSocket.
  • Knowledge base collections for sharing documents across multiple agents.
  • Real-time call actions such as scheduling, refunds, ticket handling, transfers, and call completion.
  • Built-in and cloned voices, plus browser-based testing without a phone.
  • Call recording, transcription, playback, and tool-use review.

Hints

  • Each account includes a free phone number.
  • Direct SIP can connect an existing number from a major telephony provider.
  • Supported knowledge sources include plain text, Markdown, Word, PowerPoint, Excel, HTML, and JSON.
  • Agents are billed at the API rate of $0.05 per minute of audio, with voices included and no separate platform fee.
