Grok 4.5
Kevin Bass@kevinnbass· Jul 9, 2026Grok 4.5 scores significantly better than other frontier models Opus 4.8 and GPT 5.5 across ALL professional work benchmarks.
It performs exceptionally well at law.

New renderings of SpaceX's AI satellite, called AI1.
• AI chip vendor agnostic. System architecture supports compute modules from any provider.
• 150 kW peak compute payload
• 120 kW average compute payload
• 70 kW per ton
• Wingspan: 70 meters
• Deployed height: 20 meters
• 110 m² deployable liquid radiator
• Redundant pumping loops
• Integrated micrometeoroid shielding
• 150 kW solar array
• 250 W/m²
• High-speed laser links interconnect satellites and beam AI results back to Earth through Starlink. Low-latency, high-bandwidth connection
• SpaceX-manufactured solar technology from Bastrop, Texas
Sawyer Merritt@SawyerMerritt· Jul 9, 2026SpaceX has introduced a new website for Starmind, the company's AI satellite constellation.
Back in January of this year, @SpaceX filed a request with the FCC to launch and operate a constellation of 1 million AI satellites.
The website provides info about their AI1 satellite,

Try @Grok 4.5!
Artificial Analysis@ArtificialAnlys· Jul 9, 2026Grok 4.5 is the top non-Anthropic model on AA-Briefcase, combining frontier agentic knowledge work capabilities with leading cost and time-efficiency
Yesterday @SpaceXAI released Grok 4.5, a new frontier-level model with strengths in agentic coding and knowledge work. On

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

Aaron Burnett@aaronburnett· Jul 8, 2026Grok 4.5 is looking like a success with help from Cursor data but underneath the surface we expect future Grok/Cursor model training is likely to speed up in the coming months.
We've spent several months getting up to speed on the SpaceXAI business, especially the tech

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.
Mark Zuckerberg@finkd· Jul 9, 2026(1) Today we're releasing Muse Spark 1.1 -- a strong agentic and coding model at a very low price. It's available through our new Meta Model API and in Meta AI.
