America needs to build again, and it is building.

We kick off our @corememory 4th of July American manufacturing extravaganza with the latest temple to metal built by @elonmusk and the @tesla_semi team.

This is an hour+ tour of the Tesla Semi factory in Nevada alongside @danWpriestley.

Uranus is finally getting the attention it deserves 🔵😄

Scientists want to send a mission called Uranus Orbiter and Probe — a spacecraft that would travel all the way to Uranus, drop a probe into its atmosphere, and then stay behind in orbit to study the planet, its rings, moons, magnetic field, and what’s going on deep inside.

Why Uranus? Because we’ve barely seen it up close. The only spacecraft to visit it was Voyager 2 in 1986, and that was just a quick flyby. Since then, Uranus has remained one of the Solar System’s biggest mysteries.

And it’s a weird one:
💙 it spins almost on its side
🧊 it’s one of the coldest planets in the Solar System
💎 diamonds rain down on Uranus’ core
🌀 and its magnetic field is exceptionally chaotic, tilted, and lopsided

This mission could help scientists understand not only Uranus itself, but also a whole class of planets called ice giants — which may be common around other stars, too.

So yes, NASA really does want to go much deeper into Uranus. Would you want to see a mission like this finally launch? 🚀

Another major Grok Build update just landed, packed with new features, extensive bug fixes, and meaningful performance improvements

Release Notes: v0.2.84 — 2026-07-03

Features:
• Announcements now update live during active sessions without restart or /new.
• Hiding an announcement no longer suppresses later criticals; new ones reappear automatically.
• run_terminal_cmd now requires a one-sentence description rationale in every invocation.
• ask_user_question timeout policy is now configurable in config.toml and /settings.
• Ask-Question timeout can now be toggled from /settings (Agent & Approval).
• Thinking/reasoning blocks are now shown by default while the model is working.
• Critical announcements now show a red title with a clickable [hide] button and aligned message.
• Added remote_fetch option under [features] in config.toml to disable all backend catalog and settings fetches for air-gapped environments.

Bug Fixes:
• Images pasted or read from GIF, BMP or TIFF files are now automatically converted so they work with image generation.
• Queue panel now shows action buttons on hover and the status bar displays a compact done/total task count.
• Hook matchers now correctly see the real MCP tool name instead of the internal dispatcher name.
• Copy now succeeds when running inside containers even when the terminal brand cannot be detected.
• Tool result previews no longer paint opaque panels in grok --minimal.
• grok wrap now correctly handles quoted strings and shell aliases.
• Text selection settings now correctly honor explicit keep_text_selection values even when legacy keys remain.
• Fixed a freeze that could occur when editing and sending the last message in the queue.
• Fixed a startup crash on minimal Linux systems lacking system CA certificates.

Performance:
• Grep now stops early on broad searches, returning faster results with far less memory use.
• Idle CPU and memory usage after long sessions or resume is now dramatically lower.

Finally, Grok’s Speech-to-Text is now live in Grok Build

You can now just dictate prompts directly to your coding agents using /voice or Ctrl + Space, powered by Grok Voice

Just talk naturally for like 15 minutes straight. Grok transcribes everything in real-time and gets to work instead of stopping to type every instruction

This makes it so much easier to:
• Brainstorm ideas while coding
• Describe complex changes conversationally
• Stay in flow without switching between keyboard and voice
• Interact with coding agents more naturally

As AI coding assistants get more capable, voice is becoming a first-class workflow in Grok Build

Huge unlock for anyone who thinks out loud or hates context switching

Looking forward to the long weekend

Paraguay is entering a new era of connectivity 🇵🇾

Paraguay is working with Starlink through MITIC and COPACO to bring high-speed internet to more than 1,600 schools in isolated areas

This will connect 50,000+ students and teachers to online learning, digital libraries, collaboration tools, and new opportunities

A satellite in orbit can now change the future of a classroom full of students on the ground
