Developing the intelligence for Optimus requires an incredibly power + high compute efficient chip to process the physical world with low latency. This chip is going to be magnitudes better than what we currently have, the team is very excited to get our hands on it soon!

[Elon Musk @elonmusk]

Congrats to the @Tesla_AI chip design team on taping out AI5!

AI6, Dojo3 & other exciting chips in work.

De toekomst van mobiliteit is aangebroken

FSD Supervised has been approved in the Netherlands 🇳🇱 & will begin rolling out in the country shortly! 

Trained on billions of kilometers of real-world driving data, it can drive you almost anywhere under your supervision – from residential roads to city streets & highways

No other vehicle can do this. 

We're excited to bring FSD Supervised to more European countries soon

[Tesla Optimus @Tesla_Optimus]

Optimus will be the biggest product ever made.

A general-purpose humanoid robot that can do useful work at scale will change the economics of labor & manufacturing.

Goal is to get Optimus to high-volume production as fast as possible.

If you’re great at AI, engineering, or manufacturing & want to build this, join us!

Congrats to @Tesla_AI. It’s gonna work. FSD has been so nice! I just hit 1k FSD miles myself since 14.2 with 98% miles driven with FSD

I am in a robotaxi without safety monitor

[Jim Fan @DrJimFan]

I was very late to own a Tesla but among the earliest to try out FSD v14. It's perhaps the first time I experience an AI that passes the Physical Turing Test: after a long day at work, you press a button, lay back, and couldn't tell if a neural net or a human drove you home.

Despite knowing exactly how robot learning works, I still find it magical watching the steering wheel turn by itself.

First it feels surreal, next it becomes routine. Then, like the smartphone, taking it away actively hurts. This is how humanity gets rewired and glued to god-like technologies.

Just set a new PR in the lab

Finally. Pretty late to the party

With FSD Supervised engaged, you're 7x less likely to be involved in an accident

I picked up my new Model Y a month ago taking a robotaxi to Fremont factory to pick it up. The robotaxi is just another Model Y and it drove me all the way from Palo Alto to the Fremont factory. I then FSD-ed back home both rides no interventions. The really cool thing here is you can just buy a “robotaxi” these days and have it drive you around smoothly. And once official robotaxis go driverless, my personally owned Model Y will be no different than the robotaxi fleet giving rides to customers. It’s amazing work by the AI team here.

I took delivery of a beautiful new shiny HW4 Tesla Model X today, so I immediately took it out for an FSD test drive, a bit like I used to do almost daily for 5 years. Basically... I'm amazed - it drives really, really well, smooth, confident, noticeably better than what I'm used to on HW3 (my previous car) and eons ahead of the version I remember driving up highway 280 on my first day at Tesla ~9 years ago, where I had to intervene every time the road mildly curved or sloped. (note this is v13, my car hasn't been offered the latest v14 yet)

On the highway, I felt like a passenger in some super high tech Maglev train pod - the car is locked in the center of the lane while I'm looking out from Model X's higher vantage point and its panoramic front window, listening to the (incredible) sound system, or chatting with Grok. On city streets, the car casually handled a number of tricky scenarios that I remember losing sleep over just a few years ago. It negotiated incoming cars in tight lanes, it gracefully went around construction and temporarily in-lane stationary cars, it correctly timed tricky left turns with incoming traffic from both sides, it gracefully gave way to the car that went out of order in the 4-way stop sign, it found a way to squeeze into a bumper to bumper traffic to make its turn, it overtook the bus that was loading passengers but still stopped for the stop sign that was blocked by the bus, and at the end of the route it circled around a parking lot, found a spot and... parked. Basically a flawless drive.

For context, I'm used to going out for a brief test drive around the neighborhood to return with 20 clips of things that could be improved. It's new for me to do just that and exactly like I used to, but come back with nothing. Perfect drive, no notes. I expect there's still more work for the team in the long march of 9s, but it's just so cool to see that we're beyond finding issues on any individual ~1 hour drive around the neighborhood, you actually have to go to the fleet and mine them. Back then, I processed the incredible promise of vehicle autonomy at scale (in the fully scaleable, vision only, end-to-end Tesla way) only intellectually, but now it is possible to feel it intuitively too if you just go out for a drive. Wait, of course surround video stream at 60Hz processed by a fully dedicated "driving brain" neural net will work, and it will be so much better and safer than a human driver. Did anyone else think otherwise?

I also watched @aelluswamy 's new ICCV25 talk last week (https://t.co/RdaM23kvez) that hints at some of the recent under the hood technical components driving this progress. Sensor streams (videos, maps, kinematics, audio, ...) over long contexts (e.g. ~30 seconds) go into a big neural net, steering/acceleration comes out, optionally with visualization auxiliary data. This is the dream of the complete Software 1.0 -> Software 2.0 re-write that scales fully with data streaming from millions of cars in the fleet and the compute capacity of your chip, not some engineer's clever new DoubleParkedCarHandler C++ abstraction with undefined test-time characteristics of memory and runtime. There's a lot more hints in the video on where things are going with the emerging "robotics+AI at scale stack". World reconstructors, world simulators "dreaming" dynamics, RL, all of these components general, foundational, neural net based, how the car is really just one kind of robot... are people getting this yet?

Huge congrats to the team - you're building magic objects of the future, you rock! And I love my car <3.
