DirectRobotics & physical AI
What it does

Tesla's AI and robotics division develops the Full Self-Driving (FSD) autonomous-driving software used in its cars and the Optimus humanoid robot, both built on Tesla's own custom-designed AI chips.

Why it matters

Tesla is one of very few companies simultaneously mass-manufacturing a humanoid robot (Optimus) and a widely deployed driver-assistance AI system (FSD), and it designs its own AI silicon rather than buying it from merchant chipmakers.

How it makes money

Tesla sells FSD as a paid software option/subscription to car buyers; Optimus remains in prototype and pilot production and had not yet begun broad commercial sales as of the latest reporting.

Geography

United States (Austin, Texas)

AI stack position
