Our internal assessment is that Grok 4.5 is roughly comparable to Opus 4.7, but much faster. The combination of capability, faster speed and lower cost is what makes it competitive.

We are closing the loop on real-world usefulness, not benchmarks. Hardcore engineers at Tesla & SpaceX find Grok 4.5 genuinely useful, which is what actually matters.

We will be releasing a new @CommunityNotes feature that sends you an 𝕏 Chat message if a post you interacted with is corrected

Based on strong positive feedback from customers in our beta test program, @SpaceXAI will make Grok 4.5 available to the public tomorrow.

It is an Opus-class model, but faster, more token-efficient and lower cost.

DRIVE-BY MEDIA: Most Americans believe that black women are primarily murdered by racist white men. It turns out that 99% are committed by blacks. 91% are committed by black men and 8% are committed by black women. It turns out that 0% are committed by white supremacists. Why does the media want us to think white men are the problem?

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

Last year, @elonmusk brought national attention to the paper-based federal retirement process hidden deep underground in Boyers, Pennsylvania.

The Last Day of Paper is more than a milestone, it is proof that government modernization can deliver real results for the American people.

Thank you @POTUS and @elonmusk for the initial discussions that led to this important accomplishment: https://t.co/JwdiLEt0Ko

Teams recently completed build and acceptance testing of our 1,000th Merlin 1D engine for Falcon’s first stage! With Falcon’s reusability, recovering these engines has enabled continued reliability enhancements, making Merlin one of the most reliable rocket engines ever manufactured

BREAKING: Japan is testing Starlink-powered fire hydrant signs as emergency communication hubs.

• Japan has approximately 120,000 fire hydrant signs installed nationwide.

• The technical demonstration was conducted by Shokasen Hyoshiki Co., Ltd., a company that manages fire hydrant signs across Japan.

• The test explored mounting Starlink equipment on a fire hydrant sign to provide satellite internet connectivity.

• The goal is to transform existing fire hydrant signs into temporary Wi-Fi and emergency communication hubs during disasters.

• Residents could use them to access emergency information and stay connected if cellular and terrestrial internet networks go down.

• The project is currently an early-stage technical verification and has not yet been deployed commercially or nationwide.

This demonstration shows how @elonmusk's Starlink could help keep communities connected when traditional networks are unavailable.
