Try it out x.ai/api/voice
Grok Voice Agent is absolutely insane
Watch how it handles a dinner reservation flawlessly - felt exactly like talking to a real human host
This is what AI-powered customer support looks like in 2026:
→ First response in under 1 second - 5× faster than rivals
→ 5 ultra-natural voices that talk, think, and act on your behalf
→ Full-duplex WebSocket for real-time, zero-lag conversations
→ Built-in live Web & 𝕏 search MCP support
→ Auto-detects & switches between 20 languages mid-conversation
→ 24/7 - never sleeps, never calls in sick
And the base price is just $0.05/min
For $3/hour, you get a 24/7 worker that never sleeps, never burns out, and treats every single customer with infinite patience
Build voice agents for your business right now and replace your entire support queue
Customer support is about to change forever
xAI's voice agent is hands down the most impressive AI voice agent out there right now

We have open-sourced our new 𝕏 algorithm, powered by the same transformer architecture as xAI's Grok model.
Check it out here: github.com/xai-org/x-algorit…
We will make the new 𝕏 algorithm, including all code used to determine what organic and advertising posts are recommended to users, open source in 7 days.
This will be repeated every 4 weeks, with comprehensive developer notes, to help you understand what changed.
