Tesla is preparing a more capable Optimus Gen 3 humanoid robot with major upgrades to hands, sensors, computing, battery and mobility, while signaling that leasing may be offered before broad retail sales.
Optimus Gen 3 has not been officially launched, but it is expected to debut by late 2026, with wider external deliveries targeted around the end of 2027. The new version is described as more humanlike, with a smoother outer shell that reduces exposed joints, wiring and gaps, while redesigned hips, knees and ankles aim to improve body proportions and motion.
The most important upgrade is in the hands. Earlier versions were described as having about 11 degrees of freedom, rising to roughly 20 in Optimus 2.5, while Gen 3 is reportedly targeting 22, closer to the 27 in a human hand. That matters because more finger articulation could expand the robot’s use from basic lifting to delicate work such as food preparation, household organization and small-part electronics assembly.
Tesla is also said to be developing a 3D hand sensor system with sensor counts potentially increasing by nearly three times. A published patent points to tactile sensing that could let the robot detect pressure and contact force across different parts of the hand. That would allow Optimus to react not only through vision, but also through touch when gripping or manipulating objects.
The target for Gen 3 reportedly includes lifting objects of around 40 pounds or more than 18 kilograms. The challenge is to combine that strength with fine control, allowing the same machine to move shipping boxes and handle fragile items. The complexity of the hand system helps explain why it has been treated as one of the hardest parts of the program.
Another major upgrade is the move to the AI5 chip, replacing AI3 hardware used in earlier prototypes. Performance targets previously discussed for AI5 suggest roughly 8 times the computing power of AI4, more than 9 times the memory capacity and about 5 times the memory bandwidth. For a humanoid robot, that extra local processing matters because it must balance, perceive objects, track people, understand commands and control many joints in real time.
Gen 3 is expected to keep a battery pack of about 2.3 kWh, but attention has shifted to the cell format inside it. Tesla is reportedly considering its 4680 cells instead of a more conventional LFP setup, which could improve energy density, lower weight and reduce cell count. With a projected body weight of about 125 pounds or 57 kilograms, the robot is expected to run for up to 6 hours in typical work, or closer to 4 hours under heavier loads.
Mobility is another focus, with reported running speeds of up to 4 mph. That would make Optimus more useful across larger work areas, letting it move materials and respond faster to instructions rather than staying near a fixed station. The robot is also expected to return automatically to a charger when power runs low, with recharge times estimated at 1 to 2 hours through a rear charging port.
Tesla has started early production at Fremont on a high-volume line occupying space previously used for Model S and Model X assembly. The line’s design capacity is around 1 million robots per year, though the company expects it will take at least another year or longer to approach that level. The slow ramp reflects the difficulty of validating roughly 10,000 elements spanning mechanics, durability, safety and AI.
Before large outside deliveries, thousands of robots are expected to be deployed inside Tesla facilities. The internal Optimus Academy effort is expected to involve roughly 10,000 to 20,000 robots to gather training data and refine performance. Early external use is likely to center on dangerous, repetitive industrial work and operations that benefit from 24/7 uptime.
Elon Musk has indicated that leasing is likely to come before mass sales, though both options may eventually exist. With a projected purchase price of around $20,000 to $30,000, leasing could lower the barrier for factories and households that want to test the robot before committing. No official price has been announced, but estimates place a potential monthly lease in the $200 to $500 range, a model that would require strong service, repairs, parts support and warranty policies to work at scale.
Optimus Gen 3 is shaping up as a major technical step for Tesla, but its commercial impact may depend as much on manufacturing scale and service support as on robotics performance. If leasing arrives first, the company could turn humanoid robots from a high-cost purchase into a more accessible monthly tool.
