ELON MUSK: Grok will act as the manager for Optimus. Optimus need to be able to walk up to a computer or touchscreen and use it just like a human. That requires a generalized ability to understand live video, control screens and operate computers in real time. This is being developed in partnership with SpaceXAI's Grok. The large Grok model would act as the manager, giving Optimus a series of tasks and telling it what to do.
