Tesla starts building production-quality Optimus robots, with a slow ramp ahead

Tesla says its Fremont, California, factory is now producing its first production-quality Optimus humanoid robots. Disclosed in the company’s third-quarter 2026 shareholder update, the milestone comes with a qualification: Elon Musk describes an early production phase that will ramp slowly, even as he sets a much larger output target for late 2027.

A manufacturing milestone, not a finished design

The production line occupies manufacturing space previously used to build electric vehicles. Tesla’s disclosure concerns both the robots coming off that line and the process used to make them: the company says it has established a manufacturing method suitable for a commercial Optimus product.

That does not mean Tesla has frozen the design or settled every factory step. It expects to keep changing both the robot hardware and its manufacturing methods. The company is describing a process it considers commercially suitable while acknowledging that further engineering and production improvements are still needed.

While we will continue to iterate on the hardware and manufacturing process, we have proven that the current manufacturing process for Optimus is suitable for a commercial product.

More robots and more dependable robots

Musk is targeting 20,000 Optimus robots per week by the end of 2027, according to Interesting Engineering’s account of the earnings call. That is a future production goal, not Tesla’s current output. Musk warned that scaling would involve setbacks as engineers work through the difficulties of building humanoid robots in large numbers.

The remaining engineering work also concerns how long each robot can operate dependably. Musk acknowledged that the design needs further refinement to support safe, extended operation without frequent repairs or component failures. Increasing the number of units built therefore sits alongside a separate task: improving the durability of the machines themselves.

Software is another unfinished part of the product. Musk said substantial work remains before Optimus can independently perform a broad range of activities. Tesla still needs to develop the capabilities that let the robot handle unfamiliar tasks reliably. A production-quality body does not resolve that software challenge.

For prospective buyers, the manufacturing announcement does not yet supply a timetable for broad availability. Tesla has not established when Optimus will be commercially available at scale. The Fremont milestone puts production on a new footing, but the date when customers can obtain the robots in large numbers remains unresolved.
