Tesla Optimus Gen3 Production Ramps Up: Fremont Factory Targets 1 Million Units/Year
Tesla has officially begun mass production of its Optimus Gen3 humanoid robot at the Fremont, California facility. The company's Q1 2026 roadmap confirms production will ramp up significantly starting July-August 2026, with a target annual capacity of 1 million units per year from the first-generation production line.
The Optimus Gen3 represents a significant leap forward in humanoid robotics technology. Key specifications include 22 degrees of freedom in each hand, enabling precision tasks such as threading a needle or handling fragile electronics. The robot stands at approximately 173 cm tall and weighs 57 kg, featuring an integrated black shell design that gives it a more human-like appearance.
**Production Strategy** Tesla is transforming its Fremont Model S/X production line into a dedicated Optimus manufacturing facility. Simultaneously, groundwork has begun at Giga Texas for a second-generation production line with long-term capacity targets of up to 10 million units annually. Total investments for the expansion are estimated between $5 billion and $10 billion.
CEO Elon Musk reiterated during the Q1 earnings call that humanoid robots will become Tesla's most important product ever and potentially one of the most significant in human history. The company expects commercial sales to begin by late 2027, with prices projected between $20,000 and $30,000.
**AI Integration** Optimus Gen3 runs on Tesla's FSD computer—the same neural network infrastructure powering Tesla's autonomous vehicles. The robot can learn new tasks through observation, similar to how Tesla vehicles learn from human driving footage. Currently, Optimus units are deployed in Giga Texas performing battery cell sorting, component kitting, and inventory management tasks.
