Right now we're struggling with the...

the final design of the hardware.

Like I said, it's really primarily the hand.

Not to just dismiss the rest of the robot, the rest is also important, but the hands are, the hands inclusive of the forearm are a majority of the engineering difficulty of the entire robot.

Oh, yeah.

Yeah, no problem.

Not that long.

Maybe I went a little over the top promoting Grok Imagine, but...

Well, if you wanted to do all the things that a human can do, it turns out you need a humanoid robot.

So if you wanted to do a subset, that's much easier.

But it turns out humans evolved to the shape and capabilities that we have for good reasons.

Actually, there is...

There's value to having four fingers and a thumb.

And even the pinky, actually, is quite useful.

Yeah, so at Tesla we basically had two...

different chip programs, one Dojo on the training side, and then what we call AI4, our inference chip.

The AI4 is currently shipping in all vehicles, and we're finalizing the design of AI5, which will be an immense jump from AI4.

By some metrics, the improvement in AI5 will be 40 times better than AI4.

So 40%, 40 times.

And this is because we work so closely at a very fine-grained level on the AI software and the AI hardware.
