I’m proud to be joining SpaceX and xAI with @milichab
It has become clear that software is changing fundamentally. More and more, people can shape the tools they use directly, and the ceiling of what can be built keeps rising.
What makes xAI special is the scale of its ambition: to build from first principles all the way out to the stars.
I’m especially grateful to work on products that expand human agency and freedom. That mission is deeply personal to me. My family came to the United States fleeing communism, and the belief that freedom should be part of the next generation of the internet has driven me every day since Andrew and I started Skiff. Now, we get to work on intelligence, understanding, and freedom on a universal scale.

Grok Voice agents can. redirect calls to your new Grok Voice agent, he can screen and send back to you or take a message or even troll scammers lol.. Unlimited possibilities. It’s so good now on Voice 3.0 (best in the world btw) model
You can create your own Grok Voice agent here: console.x.ai/team/default/vo…

Introducing Grok Voice 3.0, the world’s most intelligent speech-to-speech model.
It excels at resolving customer calls, responds in under a second, and costs less than other frontier models.
The internet runs on email. Now (along with buying things) your Bot can do anything you can do online, for you.
You can even just tag @bot on X, and your Bot will set it all up for you.
If you get stuck on anything let us know and we will fix it.

I'm hiring for our Talent Engineering team at @spacexai!
Looking for people who love working with exceptional humans as much as (or more than) building product. A few things that we look for:
1) You’re an engineer who can build things to get the job done, being able to 80/20 most things.
2) You care about people and you've been making intros, supporting founders, and bringing great people together for years, without calling it a job. Your skillset aligns with that of a VC (and you might be one someday!)
3) You’re naturally magnetic in communities. People take your calls because you genuinely love to help and care about them!
4) You don’t wait to be told what to do, you've been a go-getter and can get shit done.
If any of these resonate and you want to be a critical part to the inner workings of a frontier lab, then I'd love to meet!
👋 Warm intros through a mutual otherwise feel free to email me at [email protected]!

Grok @bot is now integrated into Tesla. Thanks to all the teams working hard on this.
It can handle:
- DoorDash / OpenTable / Uber Eats for pickup and restaurants on your way home or to work, while discussing what to order with family
- Discussing your work and even spinning up a PR
- Prepping documents on the way to meet clients
And more!
Tesla + Grok @bot placed the coffee order when a Cybercab drove me to work.
.@Grok in your Tesla can now do meaningful work for you
