We
– design the chips & hardware
– make the cars w/ said hardware
– collect real-world data at scale
– train the real-world AI model
– built (& continue to expand) the massive supercomputer cluster that trains it
– deploy AI directly to millions of robots on wheels
All that is shared with @Tesla_Optimus for broader applications in both the physical & digital world

@MRpoproppo Silicon comes from sand. Can most people still claim they're smarter than a B200? 🤔
English
When someone says your brain is filled with sand, it’s actually a compliment.

The company that can build its own infrastructure will eventually win, since it can turn things that would otherwise be unscalable into scalable ones.

One of the fundamental limitations of compute is energy. Hence, there is a biological limit to our brains before they get too hot or inefficient.
The same applies to robots, especially if they need to move—there is a physical limit to the thermal management and battery mass you can associate with the computation needs before running out of room for other mechanical parts.
Deploying 2M H100s would roughly take 3-4 GW. In contrast, 2M Tesla vehicles running around while providing essential heating and comfort to the human inside take less than 1/10th of that energy.
Thus, real-world AI is bound by the joules you could carry with you.

Our grandmas are actually professional programmers. 🧶

Before we had silicon chips, we had needle and thread. In the 1960s, NASA didn’t ‘upload’ code; they sewed it. To get Apollo 11 to the moon, skilled weavers (often called ‘Little Old Ladies’) literally hand-stitched software into physical objects.

Amazing abundance will be unlocked when collections of atoms and bits can both self-improve each other.
English
I often think about our winter testing picture. It represents the beauty of the vehicle and the hardness of our grit.
Beauty can grow from hard work.

@elonmusk It has been helpful for comparing products I want to purchase.

What are your initial impressions of Grok 4.20?
Major upgrades are still landing every week.
Testlabor@testerlabor
Grok 4.20 is now officially out of Beta. It's now on Auto, Fast, Expert & Heavy.

@yunta_tsai I’m sure those Lamborghini owners can hardly wait to take a Cybercab ride share rather than their Lambo. 😂😂🤣
English
Even people in Lamborghinis turned their heads at the Cybercab. The radiant magic is like the golden ticket from Charlie’s Chocolate Factory that inspires wild imagination.

Getting closer to Starship launch! 🚀
SpaceX@SpaceX
Initial Super Heavy V3 and Starbase Pad 2 activation campaign complete, wrapping up several days of testing that loaded cryogenic fuel and oxidizer on a V3 vehicle for the first time. While the 10-engine static fire ended early due to a ground-side issue, we saw successful startup on all installed Raptor 3 engines. Next up: preparing the booster for a 33-engine static fire

Humans are the only species that know how to make tools to improve their tool-calling skills in order to lift beyond their limited neuron capacity. This becomes a self-improving loop.
The same applies to digital AIs that know how to code and physical robots that know how to build.

@dannywinner1 Early morning you will be fine. Don’t go there in the middle of the day.

@yunta_tsai I’m going to Yosemite soon and have been nervous about half dome… not because of my own competence but the competence of ppl ahead of me. If they slip, they take out people below them. 😬. Probably some leadership lesson in there.
English
El Capitan seems impossible to climb, but people have climbed it multiple times, even without ropes.
Hard problems might be intimidating. But you can either scale them yourself or watch someone else climb from below.
English
Someone should make AI Oscars that host with AI videos. I'm sure the ratings will be more entertaining than the real one.
In an age where people yearn to be entertained instead of being lectured by celebrities, what a missed opportunity.

@EchoplexSE @kylaschwaberow Driving vs commute are two different things.
English
@yunta_tsai @kylaschwaberow Maybe the FSD team SHOULD include people who actually love driving, just a thought
English
Our teams hate driving. So whenever there's a new vehicle bring-up, we work extra hard until it can take us home and back—not for demo, but for our sanity.
