Tesla Shifts Fremont Factory to High-Volume Optimus Production
The automaker has converted its legacy vehicle line to mass-produce humanoid robots, aiming for 20,000 units per week by next year.

Tesla has officially begun manufacturing its Optimus humanoid robot on a high-volume assembly line within its Fremont, California facility, marking the first time the company has produced units it considers ready for commercial sale. In its third-quarter shareholder letter, the company stated that the robots rolling off this new line meet the quality standards required for a real product, confirming that the current manufacturing process is viable for a commercial item. This move signals a significant pivot from prototype testing to industrial-scale production for the humanoid division.
The production line occupies the same space within the Fremont plant that was previously dedicated to building the Model S and Model X sedans and crossovers. Tesla cleared out the old vehicle assembly equipment in just 46 days earlier this year to make room for the robot infrastructure. The facility is currently sized to handle one million units annually, and executives indicated that the bulk of the necessary equipment is already installed. Output is expected to rise steadily, with the company targeting a production rate of roughly 20,000 robots per week as the line reaches full capacity.
During Wednesday’s earnings call, Elon Musk described the production ramp-up as following a classic S-curve trajectory. He noted that while long-term growth is substantial, the initial phase involves a shallow slope as the team refines critical systems. The engineering focus is currently on improving the robot’s artificial intelligence, electromechanical design, and overall reliability. Tesla expects to complete these refinements by the end of next year, at which point it plans to begin delivering Optimus units to external companies for tasks that are dangerous, repetitive, or require around-the-clock operation.
A major strategic shift involves how the robots learn to perform tasks. Unlike Tesla’s vehicles, which gather training data from a vast fleet of millions of cars on the road, Optimus does not yet have a large user base to provide real-world data. Musk acknowledged this gap, noting that the lack of a broad fleet limits the available training data. To solve this, the company is implementing a program called the Optimus Academy, where 10,000 to 20,000 robots will practice a wide variety of tasks. Every unit produced at Fremont will contribute to this dataset, feeding the lessons learned back into the next version of the AI model.
Hardware upgrades are also in progress to support this learning process. Tesla plans to integrate its AI5 chip into the Optimus platform next year to enhance processing capabilities. Musk indicated that a new video demonstrating the robot completing tasks driven by AI, rather than preprogrammed motions, should be released within one or two months. He contrasted this approach with rival humanoid demonstrations that often rely on scripted routines, arguing that such scripted movements would not hold up in the unpredictable real world.
The supply chain is also expanding to support the growing demand. In September, Tesla certified Tuopu, Joyson, and Sanhua as mass-production partners for key Optimus components. Simultaneously, construction is underway on a much larger dedicated factory at Giga Texas. Recent drone footage shows the steel frame of the new plant nearing completion. Musk has set an ambitious long-term target for the Giga Texas facility, aiming for a production capacity of 10 million robots per year.
Executives also highlighted cost efficiencies, noting that Optimus production costs are trending toward the expected manufacturing costs of the Cybercab vehicle. This suggests the robot is being engineered for volume production from the outset, similar to Tesla’s automotive approach. However, the company acknowledged that the robot’s hands remain the most complex part of the design. Much of the current engineering effort is focused on solving the challenges associated with dexterity and durability in the hand mechanism.
As the transition from vehicle production to robot manufacturing continues in Fremont, the focus remains on balancing speed with quality. The company is working to ensure that the rapid increase in output does not compromise the reliability of the units. The upcoming months will be critical for validating the AI improvements and hardware upgrades, setting the stage for the first external deliveries planned for late next year.
