It’s time.

As usual, legacy media is misrepresenting the situation.

I just asked Tesla & SpaceX to try out Grok 4.5 to see if it solves their task, not use it no matter what!

They should continue to use other AI models if those models outperform Grok.

Grok 4.5 even ranks slightly above Fable, which is an incredibly good model, on some software benchmarks!

@brivael It’s great that they’re writing about it

Grok Build is now open source

[Jason Ginsberg @JasonBud]

We've appreciated your feedback on X. Limits are reset, Grok 4.5 is available in the EU, and Grok Build is now open source.

[Tesla Owners Silicon Valley @teslaownersSV]

BREAKING: Grok 4.5 has climbed to #2 on the FrontierSWE benchmark.

The result places Grok 4.5 among the world's top-performing AI models for software engineering tasks, highlighting its growing strength in real-world coding and agentic developer workflows.

Another milestone as xAI continues advancing Grok's coding capabilities.

Tesla has partnered with 7-Eleven Japan to begin installing Superchargers at the country’s largest convenience store chain.

The 150th Supercharger site in Japan was also the first of this new partnership, which opened on July 11 at the 7-Eleven Kawasaki Shimokodanaka East store in Kanagawa Prefecture. https://t.co/g2YFmnsqyJ

Top ⁠computer ⁠chip equipment ⁠maker ASML said its capacity expansion ​plans in 2027 and 2028 unveiled ‌today take into ⁠account ⁠demand for its tools from Elon Musk's planned ​Terafab chip production facility in Texas.

"We're in dialogue with all our customers and ​we know ... what their building plans are," ⁠CFO Roger ⁠Dassen ​said on a call. "Terafab is also part of ​those plans."

Dassen also said ASML was close to fully booking its 2027 EUV capacity and ⁠had already secured a substantial number of 2028 extreme ultraviolet lithography (EUV) orders.

Grok 4.5 is built for real-world engineering. It excels in large codebases and handles long-running tasks that span multiple repositories, hundreds of skills, and a variety of tools.

Look at these photos

Falcon 9 soaring into the sky. Falcon Heavy and Starship ready for the next mission. Starlink antennas simple, clean, ready for any terrain. The Boring Company’s machine that looks like industrial sculpture. Futuristic tunnels full of Teslas. And the man whose vision stands behind it all.
It’s not a coincidence. It’s not just “technology.”
It’s class itself.

Zero unnecessary ornaments. Zero exaggeration. Just a pure, very high-quality product. You hold it in your hand, step inside, or look at it and immediately feel that everything is refined to the last detail. It works. It looks right. It lasts.

Elon Musk has this rare quality: he’s a man with class. He doesn’t flaunt luxury or add things just “because they photograph well.” He chooses simplicity but the kind that’s executed perfectly. And he transferred exactly that same philosophy to his companies.

The result? Engineering at the level of fashion. Design that’s modern yet has timeless elegance. Products that don’t just do the job they impress with their quality and quiet confidence.

It’s no accident that the rocket looks like a work of art.

That a Tesla interior feels minimalist yet luxurious.
That a Starlink dish looks like it was designed by someone who understands aesthetics, not just connectivity.

They all share one common thread: class.
Not the loud, flashy kind.
The real kind quiet, self-assured, and uncompromising.

If you value things that are simply well-made without unnecessary bling, but full of character and top-tier quality this is the essence of what Elon has built.

INSANE Drone Flyover of Tesla Giga Texas!

I flew my FPV drone right over Tesla’s massive Gigafactory in Texas and captured epic aerial views of the factory.

The sheer size of this place is mind-blowing!

Watch the full flyover and see why Giga Texas is one of the biggest factories in the world.

Good reason to try Grok 4.5 with Grok Build. It gets better every day!

That’s how making a startup succeed goes

"@elonmusk is working on the most important areas of A.I. xAI is working on foundation cognitive intelligence A.I., Tesla is working on autonomous vehicles. Optimus is for humanoid robotics. He is very optimistic about the future of A.I."
