Impressive Intelligence vs. Cost for Grok 4.5

I think given terafab + the Tesla FSD team's expertise in making very efficient AI models, this advantage will only continue to compound

Consistent with the simulation hypothesis.

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

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

President Trump called for a celebration worthy of our great nation’s 250th birthday, and @SecWar and the Department of War delivered an unforgettable tribute.

NASA was honored to play a small part. Here’s a behind-the-scenes look from the cockpit. 🇺🇸✈️

July 12 will mark four years of science from @NASAWebb!

To celebrate this science anniversary, Webb’s vision cut through the thick dust of the galaxy Centaurus A to give us a clearer, more detailed view of its starry center than ever before.
