Grok Bot can now place and manage phone calls for users

From chat to real-world tasks

Elon Musk recently announced that Grok's @Bot assistant can now place phone calls on behalf of its users. This update allows the AI to move beyond simple text interactions into the realm of practical task automation. Users can describe a specific need, and the bot handles the dialing and conversation.

The workflow is designed to be end-to-end, meaning the user does not need to manage the middle steps of the call. Grok Bot can speak with whoever answers the phone, handle specific requests, and then report back to the user. This represents a significant step toward autonomous personal assistants.

While other major tech companies have signaled ambitions for similar features, xAI is shipping a consumer-facing product. The goal is to let users delegate repetitive tasks like making restaurant reservations or checking on warranty service inquiries. It aims to remove the friction of manual phone interactions from the user's daily routine.

Navigating menus and transcripts

One of the most functional aspects of this update is the bot's ability to handle complex phone systems. According to reports from 247wallst.com, the agent can sit on hold and navigate interactive voice response (IVR) menus by pressing keys. It can even be transferred between different departments without dropping the task.

A key differentiator for Grok Bot is the way it handles information after a call concludes. Unlike some previous attempts at AI calling, Grok Bot provides a live transcript as the conversation unfolds. It then sends back a clean, written summary of the entire interaction for the user to review.

This pattern ensures that the user remains informed even when they are not actively speaking. It creates a reviewable record of what was discussed and agreed upon. This transparency is intended to build trust as the AI takes on more responsibility for personal communications.

The technology of Grok Voice 3.0

The engine powering these capabilities is Grok Voice 3.0, which was released publicly on October 14. This model was designed to handle natural two-way conversation without the awkward pauses that often give away a robot. It achieved a 97% success rate on the Full Duplex Bench, a metric used to measure conversational flow.

Speed is a critical component of making these calls feel human. xAI reports that Grok Voice 3.0 delivers initial responses in under 800 milliseconds. This is a 40% reduction in latency compared to the previous version, which helps the bot stay in sync with a human caller.

The model has already been stress-tested in high-volume environments before reaching the general public. It currently handles millions of daily conversations inside Tesla vehicles. It also powers Starlink call centers, where it resolves about 70% of customer calls without needing a human agent.

Access and enterprise potential

Users can access Grok Bot through various subscription paths, including paid individual Cursor plans and several SuperGrok tiers. For those who want to build their own voice agents, xAI offers the Grok Voice 3.0 API. The pricing for this API is set at $0.08 per minute, which remains the same as the previous version.

While the calling feature is currently an app-based tool, there is significant potential for broader integration. Because Tesla vehicles already run on the Grok Voice 3.0 infrastructure, owners may see these capabilities move into the car eventually. For now, the primary use case is using the mobile app to delegate calls and receive summaries.

Looking forward, xAI is likely to pitch the Voice Agent API to third-party businesses. The success seen at Starlink suggests that the technology is ready for large-scale enterprise use. This could lead to a wider adoption of AI agents handling customer service across various industries.
