Tesla has begun producing its long-awaited humanoid robot, Optimus, at its Fremont factory, the company said in its quarterly earnings report.

"The bots coming off this line are the first production-quality bots that we have manufactured," Tesla said, saying the current manufacturing process is "suitable for a commercial product."

"There's still some things we need to tweak about the design, because you need to deliver a robot that is safe and reliable and has long duration," CEO Elon Musk said on Tesla's Q3 earnings call. "It can't, like, wear out after a month."

Musk said the company will take at least a year to scale up Optimus production to 20,000 units a week in Fremont. He said he expects to begin delivering Optimus to customers at the end of next year.

Musk tempered expectations about how quickly Tesla can scale up Optimus production because it is "such a radically new product." He said the early stages of production will be "somewhat bumpy" because "there's like 10,000 things that have to go right" to build the robot. One of the big challenges Musk outlined is building robot hands.

Musk said Tesla is building an "Optimus Academy," where robots will practice tasks and generate data to improve the AI models that power them. The company also plans to install its next-generation AI5 chip in Optimus in April, which will give the robots more computing power and be a "big step change in intelligence," Musk said.

The latest version of Optimus has not been unveiled. Musk said he expects to release a video of Optimus within one or two months. He previously said Tesla was keeping the robot under wraps to prevent competitors from copying its design.

Tesla stopped producing the Model S and Model X at its Fremont, California, plant earlier this year to make room for an Optimus line designed to eventually produce a million robots a year. A second line under construction in Austin is planned to have an annual capacity of 10 million robots.

Tesla is competing in a crowded humanoid market. Agility Robotics, which plans to go public, has deployed its Digit robot across nine customer facilities, while Figure AI has announced deployments in logistics and distribution centers this year. Sunday Robotics, 1X, and Weave Robotics are preparing to ship robots into homes this fall.
