Grok Voice just got a major upgrade

SpaceXAI released 21 new flagship voices for Grok, joining the original five

All of them are multilingual and available now through:
• Realtime Voice Agent API
• Text-to-Speech API
• Grok Voice Agent Builder

This is not just “more voices”

SpaceXAI is building a full voice layer for AI agents:
Support agents, characters, commentary, advertising, education, wellness, customer service

Every voice is designed for a different use case, with support for 25+ languages

The original Grok voices - Ara, Eve, Leo, Rex, and Sal....also got upgraded with better pacing, phrasing, emphasis, and naturalness

And builders can now create custom voice agents directly inside the SpaceXAI console

Elon Musk is an American by blood

His grandfather, Joshua Haldeman (6’6”) and father to Maye Musk, was born in 1902 in Pequot Lakes, Minnesota, and even paid his way through college by competing in rodeos, the most American thing imaginable.

Teslas are the most American-made cars

🇺🇸 Happy 250th birthday, America 🇺🇸

Project Hail Mary is now on Prime Video, free for Prime members everywhere.

It’s my favorite movie that I've seen in a long time. Truly outstanding and unique. Phil Lord and Chris Miller pulled off something remarkable, Ryan Gosling is amazing, and none of this happens without Andy Weir’s compelling book.

If you missed it in theaters, now's your chance. And, if you already saw it, it's an easy way to rewatch.

Think you'll enjoy.

Happy Birthday America, Land of the Free.

Don’t give up on the First, Second, Fourth, and Ninth Amendments.

They’re unique, and your freedom - and the worlds’ - depends on them.

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? 🚀

Good explanation of why some people find “wealth” inexplicable

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.

• 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.
