Excited to release Grok 4.5 with @SpaceXAI.
It's an Opus-class model that's fast and low cost. It's a significant step up over any model we've developed so far, including Composer 2.5, and has become the daily driver for many on our team.
First of many releases. More soon.
Cursor@cursor_ai· Jul 8, 2026We've partnered with SpaceXAI to train Grok 4.5.
It’s our most powerful model yet and the first we've built for more than software engineering.

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.

An inspiring vision of the future is needed
Samo Burja@SamoBurja· Jul 8, 2026Alex Karp is right. There is a deep nihilism among European elites to an extent European citizens would find shocking.
The shopkeeper, the farmer, and the car mechanic think there will be an England or a Poland in 2100; the university professor, journalist, and prime minister

There was literally a Bolshevik takeover of the Smithsonian.
Democrats can never be allowed to take power again.
Rapid Response 47@RapidResponse47· Jul 7, 2026This is just a sample; the full 162-page report lays out the entire Radical Left ideological capture of the Smithsonian — which the Trump Administration is rightfully correcting.

Has been my regular work horse for weeks. Impressive indeed.
Elon Musk@elonmusk· Jul 8, 2026Based 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.

We will continue to make refinements to the Grok Build harness and the 1.5T foundation model almost every day in response to user requests.
The 2T model will finish training this month and be available to customers next month.

Correct
tetsuo@tetsuoai· Jul 8, 2026Grok 4.5 goes public tomorrow. Here’s everything that’s known.
The model runs on V9, xAI’s new 1.5 trillion parameter foundation, roughly three times the size of the v8-small architecture behind Grok 4.3. It’s the largest model the company has shipped, trained on Blackwell GPUs

America, the Beautiful
Dustin@r0ck3t23· Jul 7, 2026Elon Musk just said the one thing about America they made sure you’d never learn.
The one thing that should’ve made you proud, not ashamed.
Musk: “After World War 2, the US could have basically taken over the world and any country. Like we got nukes, nobody else got nukes. We

With full autonomy and maximized ride-hailing, Cybercab is projected to nearly halve emissions per mile compared to Model 3 + Model Y
Also, a personal car sits parked ~95% of the time. Cybercab keeps driving, doing the work of several cars. This means fewer cars needed, more people moved, less emissions overall

With just one year in orbit, the first FireSat satellite has already spotted wildfires invisible to existing satellites. After a successful launch early this morning, 3 more satellites joined the constellation, bringing us one step closer to our ultimate goal of near real-time wildfire updates every 20 minutes.
Thanks to @EarthFireAll @MuonSpace @MooreFound @BezosEarthFund for the partnership, & @SpaceX for the ride up!

SpaceX says over 90% of its future market is AI, not space. @DMaguireARK, ACA breaks down what that means: orbital data centers, a potential $28.5 trillion Total Addressable Market (TAM), and why Starship is the only vehicle that can get there.
