Elon Musk: “The reason I felt that it was important to acquire Twitter was because I could feel the walls closing in. It was outrageous that they suspended the account of a sitting president.

I think it was only a matter of time before they suspended my account.

Twitter and pretty much all the social media companies, Google and everyone are controlled by far-left activists. That’s the truth of it.

How do you know what’s real when it’s all filtered through a far-left San Francisco Berkeley lens?

They just manipulate the truth constantly."

In the UK, a Tunisian immigrant tried to sexually assault a 14-year-old girl and was caught by a local patriot group.

He claimed raping non-Muslim women is allowed under Sharia Law.

Deport radical Islamists and ban their immigration before it’s too late?

A. Yes
B. No

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.

[Elon Musk @elonmusk]

Try @Grok 4.5!

The upcoming wave of SpaceXAI Grok updates is insane

Grok 4.5:
The 1.5T foundation model is being refined almost daily, and its context window is expected to jump to 1M tokens, possibly as soon as next week

Next model:
The 2T foundation model is expected to finish training this month and become available to customers next month

Grok Build:
The harness is getting refinements almost every day based on user feedback. New features, fixes, and workflow improvements are landing at ridiculous speed

Inference:
SpaceXAI is working on internally developed C/C++ inference mapped directly to GB300 hardware, which could double speed or more

Agentic Imagine:
Grok will be able to call Imagine as a tool in agentic mode for image and video generation

That is going to be huge for game developers, designers, builders, and anyone creating interactive worlds

But the biggest thing is this:
Grok is being built for real-world engineering

Grok 4.5 early beta access was given to Tesla and SpaceX engineers, with feedback coming from real engineering teams solving real-world problems

Next month’s release is expected to be another massive step-change improvement as SpaceXAI closes the loop on real-world engineering problems at Tesla, SpaceX, Neuralink, and Boring Company

And from now through the end of 2026, Elon said a new from-scratch foundation model is expected to ship every month

Consistent with the simulation hypothesis.

Like a video game, objects are randomly generated, with positional certainty only when observed.

grok 4.5 is seriously good. it's going in the direction which i'm hoping to see more of -- an emphasize on speed as well as intelligence. i'm noticing in my own work that speed is often the bottleneck now. the grok build tui is also very well done. bullish!

but the bigger signal beyond the model is that the team over there has officially propped up the model factory. they have the compute, the talent, the data, and leaders in place to make a run for the top. never bet against elon, @milichab, and team. they're the real deal. we love some good competition.

Mark Zuckerberg hasn’t posted since 2023.

X is the global town square — this is where news happens.

Interesting comparison of Grok & Opus

1M+ context window coming soon

Kardashev II or we’re not a serious civilization

Moon and Mars are necessary steps to this

Good review of Grok 4.5

[Elon Musk @elonmusk]

Try out Grok 4.5!
