Tesla begins mass production of Optimus robots
The automaker has shifted its Fremont factory to a high-volume robot line, aiming for commercial delivery by the end of next year.

Tesla has officially started producing its Optimus humanoid robots on a dedicated high-volume assembly line within its Fremont, California, facility. In a third-quarter shareholder letter, the company confirmed that the units rolling off this new line represent the first production-quality versions of the robot. Tesla stated that it has validated the current manufacturing process as suitable for a commercial product, marking a significant transition from prototype development to industrial output.
The production shift required a rapid reconfiguration of the factory floor. The space previously used to build the Model S and Model X sedans and SUVs was cleared in 46 days earlier this spring. This area has been converted to a robot production setup capable of handling one million units annually. During an earnings call on Wednesday, CEO Elon Musk indicated that most of the necessary equipment for this capacity is already installed in Fremont. He noted that output is expected to rise toward roughly 20,000 robots per week as the line reaches full speed.
Musk characterized the production increase as following a classic S-curve, noting that the initial growth phase will be relatively shallow. The engineering team is currently focused on refining the robot's artificial intelligence, electromechanical design, reliability, and service life. Tesla plans to complete these refinements by the end of next year. At that point, the company intends to begin delivering Optimus units to external companies for tasks that are dangerous, repetitive, or require around-the-clock operation.
A central challenge in scaling the robot has been the lack of a large fleet to generate training data, unlike Tesla's autonomous vehicle program which relies on millions of cars. To address this, Tesla is implementing an internal program dubbed the Optimus Academy. This initiative involves using between 10,000 and 20,000 robots to practice a wide variety of tasks. The data generated by these units will be fed back into the system to improve the next version of the AI model, with every robot produced in Fremont contributing to this learning cycle.
Hardware upgrades are also imminent. Tesla plans to integrate its AI5 chip into the Optimus platform next year. Musk stated that a new video demonstration is expected within one or two months, which will show the robot completing tasks driven by AI rather than preprogrammed motions. He contrasted this approach with rival humanoid robot demonstrations that often rely on scripted routines, arguing that such methods would not hold up in real-world conditions.
The supply chain for the program is also becoming established. In September, Tesla certified Tuopu, Joyson, and Sanhua as mass production partners for Optimus components. Simultaneously, a much larger facility dedicated to Optimus is under construction at Giga Texas. Recent drone footage showed the steel frame of that plant nearing completion, with Musk setting a long-term production target of 10 million robots per year for that location.
Company executives noted that Optimus production costs are trending toward the expected manufacturing cost of the Cybercab, indicating the robot is engineered for high-volume efficiency from the outset. Despite these advancements, the robot's hands remain the most difficult component of the design. Musk highlighted this challenge at the X Takeover event earlier this month, noting that a significant portion of current engineering efforts is focused on solving this specific issue.
Next steps for Tesla include the continued ramp-up of the Fremont line and the completion of the AI and reliability testing phase by the end of next year. The company will also proceed with the construction of the Giga Texas plant and the integration of the AI5 chip. Commercial deliveries to outside partners are targeted to begin once these internal milestones are achieved.
