BREAKING: SpaceX’s Starship just got another lunar customer. Japan’s ispace will use SpaceX’s Starship for Moon cargo missions.
• ispace signed an agreement with SpaceX to secure 500 kg of payload capacity on Starship.
• First mission is targeted to launch as early as 2030 through ispace’s new Lunar Access Integration service.
• The service is designed to make it easier for companies, governments, and research organizations to send payloads to the Moon.
• Customers can fly payloads ranging from a few kilograms up to 500 kg on shared Starship missions.
“We are very pleased to be able to offer the new Lunar Access Integration service utilizing Starship’s payload space… High-capacity, relatively low-cost lunar transport… is essential to realizing the sustainable lunar economy that ispace aims to create.”
— ispace Founder & CEO Takeshi Hakamada

Grok 4.5 is actually insane.
I'm one step closer to launching my new 3D Home Plan Builder. Powered by Grok 4.5 and Grok Imagine. 🚀
Grok 4.5 just crushed it: designed the entire 2D + 3D plan inside the app in under 1 minute at a fraction of the cost of Opus.
Launching tomorrow! 🔥

Cool that Grok 4.5 is #1 in some respects, even with respect to Fable 5
Artificial Analysis@ArtificialAnlys· Jul 9, 2026SpaceXAI's Grok 4.5 takes the #1 spot on AutomationBench-AA with a score of 51%, ahead of Claude Fable 5 (49%) and Claude Opus 4.8 (48%) at roughly a quarter of their cost per task - the first model to complete more than half of workflow objectives without breaking any business

Wow… within 5 minutes my kids built this game called the Tesla City with Grok 4.5.
It’s a simple Tesla arcade game in SF where:
1/ You can choose a Tesla (3 / Y / S / X / Cybertruck / Roadster / Semi / Cybercab)
2/ Give robotaxi rides - pickup and drop people off for $
3/ Can upgrade your car with the $ (buy new weapons, etc.)
4/ Fight gas cars with blasters, homing missiles, EMP & plasma, as they try to attack you to prevent you from completing Robotaxi rides.
GROK 4.5 is next level! 🔥
Teslaconomics@Teslaconomics· Jul 8, 2026My 5 and 7 yr old are ready to cook with Grok 4.5!
It’s going to be a fun summer…

Grok 4.5 delivering Fable level performance at like 1/17th the cost! 😮 @elonmusk

In fairness, Fable is definitely better than Grok 4.5, but most tasks don’t require Fable-level capability

BREAKING: Tesla Cybertruck’s bulletproof body helped protect a toddler, an infant, and neighbors during a shooting.
Cybertruck became a real-life shelter during a chaotic 4th of July neighborhood party.
• Owner says guns were drawn after an altercation
• Cybertruck sheltered a toddler, an infant & neighbors until police arrived
• Earlier, the truck was even powering the block party
• “You hope you never need that kind of protection, but in that moment, I was very glad it was there.”

Rate of improvement is 🚀🚀
Aman Sanger@amanrsanger· Jul 8, 2026Very excited for this model. It’s an enormous improvement over composer 2.5 and trained entirely from scratch. It’s been a pleasure working with the SpaceXAI team on it.
Even more excited by the slope of the effort and the models to come.

Rate of improvement is accelerating.
Users should notice a meaningful improvement in the usefulness of the Grok Build harness with our V9 foundation model (aka Grok 4.5) every week.
Gavin Baker@GavinSBaker· Jul 8, 2026Grok 4.5.
Pareto dominant for coding by the numbers.
We will see on the all-important vibes.
Instinct is the benchmarks are likely directionally accurate given the stated focus on real world utility.

Grok 4.5 is not yet using our internally developed C/C++ inference software that exact maps to the GB300 hardware. Doubling or more of the current speed is probably achievable.
Farzad 🇺🇸 🇮🇷@farzyness· Jul 8, 2026I think AI has just hit a gigantic threshold, and Grok 4.5 is the PERFECT example as to why that is.
One of the hardest parts of working with AI is iterating on a project or task that you're working on.
As the models have gotten smarter (and more expensive), it's taking longer

Artificial Analysis@ArtificialAnlys· Jul 8, 2026SpaceXAI’s Grok 4.5 scores 54 to place fourth on the Artificial Analysis Intelligence Index following only Fable 5, GPT-5.5, and Opus 4.8. It scores on par with GPT-5.5 in Codex on the Artificial Analysis Coding Agent Index in the Grok Build harness, at much lower cost

Grok 4.5 in Grok Build also stands out for its efficiency. Grok 4.5 in Grok Build cost $2.49 per task while Fable 5 in Claude Code cost $11.80 and GPT-5.5 in Codex $5.07. This is driven by relatively low token pricing and the model using far fewer tokens than comparable models (1.9M average tokens used per task), significantly less than Fable 5 in Claude Code (7.2M) and GPT-5.5 in Codex (6.2M)

Danny Limanseta@DannyLimanseta· Jul 8, 2026I got to try Grok 4.5 in early access in Cursor for the past few days and I absolutely enjoyed it.
It feels like Opus 4.8 at 2x the speed at a much cheaper price point.
I tasked it to brainstorm > plan > implement a big feature for my game (this act 1 boss fight) and it did
