Introducing Voice Agent Builder: a no-code platform to create human-like voice agents with Grok Voice. Available today at $0.05 / min.

It's for operators and developers who want production voice agents without building from scratch. Comes with telephony, knowledge retrieval, tools, guardrails, and observability. You can also use what you already have: Bring existing phone numbers, APIs, and MCPs.

Most voice stacks stitch together three APIs: speech-to-text, a language model, and text-to-speech—often with each stage hosted by a different provider. Every hop adds cost, latency, and new failure modes. Voice Agent Builder is one interface built for Grok Voice, tightly coupled to the model.

Every account includes a free phone number to get started. We're launching today in beta: Try it now → Read more →

includes a free phone number this is massive

so if i wanna talk to my agent for 1h a day, thats $3. not bad actually, when you consider voice clonning could record the background of a movie with any actor you like

wow you guys cooked🤯

Weekly limits on Grok for SuperGrok subscribers??? You guys are really making things difficult! Seriously? Weekly limits for subscribers?

Please revert to the old method for tracking limits. With the new weekly limits, even those of us on the SuperGrok subscription are hitting the cap extremely quickly. To avoid this, I'm forced to resort to using other AI tools, which makes my Grok subscription pointless. Look at the feedback from hundreds of users. This is clearly creating obstacles for your paying subscribers.

@HarshitKhemani whoa

such great work by the team 🙇 feel free to send any feedback my way!

This meme is still undefeated

It works really well! I also made a video of how it works 🤣

Really amazed by @xai consistently shipping updates 🚀

Very cool!

Is this the future of voice AI? 🤔 A no-code Voice Agent Builder with human-like voices feels like a huge step for creators and businesses

When I preview my custom voice it sounds great, but when I actually call the agent (with the same voice attached) it sounds nothing like my custom voice. What gives?

We're adding Grok Voice to the board right now. We benchmark voice agents on thousands of calls, grading what agents said vs what they actually did. Grok Voice results coming soon:

I would say it's very inexpensive compared to the average person's monthly salary and the number of minutes it takes to communicate with clients, colleagues, that annoying wife and her mother.😃😉

the new hello world is going to talk back

@wholemars The real Siri or even better Jarvis from Iron Man.

HUGE release. congratulations team 👏

Yet the X API charges 20 cents for a post with a link. Make it make sense.

Wonder how human it actually sounds... might be time to start replacing customer support agents

xAI is making voice agents stupidly easy. New Voice Agent Builder lets you go from idea to production voice agent in under 2 minutes. No code, built-in phone system, tools, and safety layers. They’re doing speech-to-speech natively, which should make these agents feel way more natural. This one actually feels like a real step forward.

About to cook with this

for 3 dollars an hour if you are agent is talking for the whole 60 mins you can fire your entire customer service department!
