Tesla just revealed a new Optimus prototype, and this one runs on Grok, xAI’s in-house language model. In this episode, we break down the quiet debut hidden inside a recruitment video, the robot’s improved design, and why task automation — not flashy stunts — is the real milestone here. We also look at how Grok changes the way Optimus learns and adapts, what this means for Tesla’s factories, and how it fits into Elon Musk’s push to unify AI across robots, cars, and software.
