Tesla has built an "Optimus Academy" where robots can learn through "self-play," Musk told investors.

The EV giant said on Wednesday that it had begun production of Optimus.

Tesla is sending its Optimus humanoid robot back to school.

Speaking on the company's earnings call on Wednesday, CEO Elon Musk compared training the EV maker's humanoid robot to raising a toddler.

Musk said that while Tesla's autonomous driving models can learn from data collected by its massive fleet of vehicles, its Optimus robot has to learn by watching people do tasks and practicing them itself, a process similar to how humans learn.

"You can see this when you have a toddler, and they initially are sort of wobbly, and they don't know how to do things, and eventually, they learn to wipe their own ass, which is a big milestone," Musk told investors.

"They learn to read and do all sorts of things, and they learn this by playing.

And we actually need Optimus to play at scale in order to have it be really good at tasks in the real world," Musk said.

Musk said Tesla expects to begin delivering Optimus to consumers by the end of 2027.

"For Optimus to get the training data we need, we actually need to make a lot of Optimi.

So we need to make, I think, on the order of 10,000 or 20,000 bots and then have them do self-play," said Musk.
