Grok Build is now fully open source, and SpaceXAI has made its privacy-first approach even stronger
SpaceXAI has officially:
• Open-sourced the Grok Build harness CLI
• Reset usage limits for all users
• Disabled data retention by default
• Deleted all previously retained coding data
• Made the harness fully local-first, allowing you to run it with your own inference
Since launch, Grok Build has supported Zero Data Retention (ZDR) for users who opted in
Now, based on community feedback, SpaceXAI has gone a step further: Data retention is now OFF by default for everyone
Your coding sessions remain private by default, with retention entirely under your control
By combining an open-source harness, local-first execution, zero retention by default, and the deletion of previously retained coding data, SpaceXAI is setting a new standard for privacy in AI coding tools
Transparent, open, and built to give users complete control over their data
SpaceXAI@SpaceXAI· Jul 15, 2026We've open-sourced Grok Build and have reset usage limits for all users.
Open sourcing Grok Build allows anyone to support making a reliable and robust harness. Check out our code, including the Git repo for the Grok Build CLI.

orbital data centers have one glaring constraint few are discussing publicly: inference network coherence. We tackled it this week in our analysis "The Orbital Inference Containment Tax"
tbf we mostly hand-waved coherence in our early ODC models (other things to learn first),

GPU average power consumption if it’s doing inference over the course of 24 hours is ~2/3 of its peak power, even if you’re super efficient.
SpaceX AI Sat V1 peak power spec has been raised to ~250kW (battery-assisted), with average power of ~160kW. Will be able to handle an NVL72 Ruben rack.
This is just version 1.

An important piece from Demis. We need more of this kind of thinking. A good reminder that the goal is a frontier ecosystem that promotes innovation and choice, while avoiding any one model drop that breaks the world!

Showing more content from people you follow has been one of the fixes.
The algorithm not barraging you with similar content due to a few likes is another.
i like teslas@iliketeslas· Jul 15, 2026The only thing that needs correcting in the algorithm is that if I like a World Cup post it doesn’t mean I want to be flooded with World Cup posts , same with other topics. Give me 90% people I follow and random other topics please.

He was anti-human. He made things up about population growth to persuade people that fewer humans should exist.
How many fewer millions of humans knew and enjoyed parents, children, friends, life because of Paul Ehrlich?
He was the grand priest of extinctionism.

An initial startup idea can't usually be both grand and precise. In practice they're usually either grand and vague or precise and small. Precise and small is better. You know who your initial users are, and you expand outward. With grand and vague you can't even get started.

I've inspected the open-sourced Grok Build so you don't have to. Here's exactly what data it sends (and what stays local):
Core (unavoidable)→ Your prompts/conversations + tool calls go to xAI's inference API. That's the whole point of the CLI.
Everything else is off by default — no Mixpanel, no Sentry, no product telemetry unless you explicitly turn it on. Even the auto-update check is a simple version GET you can disable in config.
Purely local stuff (crash reports, debug logs, secret redaction, auth) never touches the network. All telemetry paths also scrub secrets before anything is sent.
