Optimus Gen 3: what we know about Tesla's next humanoid robot

Tesla's third-generation Optimus is the version that is supposed to turn the humanoid robot from a demo into a product. Its public debut has been delayed more than once, but a fair amount is already known.

The delay

Tesla originally aimed to show Optimus Gen 3 before the end of the first quarter of 2026. On March 31, Musk said the robot was already walking around but needed some finishing touches before it could be shown. The reveal was then expected around the middle of the year, and it has still not taken place as a full public presentation. Musk has also said he is wary of showing the design too early because competitors might copy it.

What is new

• Hands: the biggest upgrade. The new hands reportedly have 22 degrees of freedom, allowing far more precise movements than earlier versions.
• Learning by watching: Tesla trains Optimus partly through imitation. Workers wear camera-equipped gear while doing everyday tasks, so the robot can learn from their movements.
• More training locations: training has expanded from Fremont to Gigafactory Texas.

What it does today

According to Tesla, early versions of Optimus perform simple tasks in its own factories. Musk expects more complex factory work by the end of 2026 and, possibly, first consumer uses from 2027. Outside observers note that the robots still work under supervision and struggle with tasks they were not trained for.

Why Gen 3 matters

Gen 3 is the design Tesla wants to mass-produce, first on former Model S and X lines in Fremont and later in a dedicated factory in Texas. If the hands and the learning approach deliver, Optimus becomes useful at scale. If not, the gap between Tesla's robot ambitions and reality will become harder to explain.

What to watch

A full public reveal, real figures on units built, and a first price for outside customers. Tesla's quarterly calls are the most likely place for each of these.
