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.

usable, real-world software is the only eval that matters Benji’s work on terafab.ai shows what the current, still-beta version of Grok Build is capable of.

Gave the Terafab website a makeover. Designed and built entirely with Grok Build → terafab.ai

beyond web design, our improvements to Grok Build are primarily validated on actual use cases – everything from brake testing to writing performant C, generating graphs, and working on windows

Grok Build is able to write code, deploy to a phone on revyl, and look at the screen to check its own work. no human in the loop. watching it edit, hot-reload, and screenshot to verify in real time is genuinely wild.

In this version of the Grok Build created game Space Groks, Grok has again used Imagine Image and Video for the assets & cutscenes and this time, it features a first-person cockpit view that is very reminiscent of Rebel Assault II, which was a 32-bit game.

grok-build-0.1 is now available via the xAI API in public beta. This is the same model that powers the Grok Build CLI and excels at agentic coding. Priced at $1/m input and $2/m output, it’s extremely cost effective, intelligent, and fast.
