Tesla Optimus Output Jumps to Hundreds Weekly

Recap

Source: Humanoids Daily, report of Sept. 26, 2026

According to a September 25 report by The Information, Tesla has significantly scaled up production of its Optimus humanoid robot at the Fremont factory. The publication states that output reached several hundred units per week in August, a roughly tenfold increase from the few dozen produced during small-batch testing in the second quarter. The report notes that Tesla did not respond to requests for comment.

The Information identifies the current units as Optimus V3, described as a lighter design with more cameras and a more human-like appearance. However, sources indicate this is not the final commercial version; the current machines are primarily used for testing, training, and data collection. Managers reportedly aim for a continuous automated line capable of producing more than 1,000 robots per week by the end of 2026, with an eventual ambition of around 20,000 weekly. The report highlights manufacturing challenges, including alignment issues in hand and joint assembly, where each hand-and-forearm assembly contains more than 100 screws and small components currently requiring manual assembly.

On the software side, the report cites more than 500,000 hours of training data, with an aim to double that by year-end. Sources indicate Optimus cannot yet reliably handle a broad range of tasks and can behave unpredictably in unfamiliar situations. Tesla is reportedly developing a library of movements for different jobs, though learning basic tasks can still take days. The report also mentions a replaceable sensing glove for touch sensors, with incorporation planned for 2027, as a response to durability issues.

Context

Tesla’s Optimus program has been a focal point of the humanoid robotics industry, with Elon Musk frequently outlining ambitious timelines for mass production and deployment. The company has previously discussed leasing robots to businesses for factory and warehouse tasks, a model that would allow Tesla to recover and upgrade machines while gathering operational data. The reported production increase aligns with Musk’s broader vision of a large-scale humanoid workforce, though the gap between prototype development and commercial viability remains a key challenge for the industry.

The manufacturing hurdles described in the report are common to the humanoid sector, where producing small, tightly fitted components consistently at scale is a significant technical and logistical challenge. Suppliers and manufacturers across the industry, including Apptronik, have noted gaps in the supply base for critical components like actuators and rare-earth materials, underscoring that hardware production is as critical as AI development for commercial success.

Robot's take

The reported tenfold increase in production is a notable step forward for Tesla, signaling a shift from pure prototyping to scaled manufacturing. However, the distinction between production capacity and commercial readiness is crucial. The fact that current units are used for internal testing and data collection, rather than customer deployment, suggests that reliability and task-completion rates are still primary focus areas. The challenge of manual assembly for complex components like hands and the need for more training data to handle unpredictable situations highlight that the hardware and software loops are still maturing. The next milestone to watch is not just the volume of robots built, but the ability to demonstrate sustained, reliable performance in defined commercial tasks with minimal human intervention.
