Digital Optimus is computer-use: real-time video of a screen with controls out, the same photons-in/controls-out loop as a self-driving car, so a physical Optimus can operate any computer. SpaceX's large model assigns it tasks.
"we have digital Optimus which is basically driving a computer screen"
"Digital Optimus is different: real-time video human emulation"
"We’re making interesting progress here. Digital Optimus can play about halfway through the Diablo campaign so far just by looking at the screen like a human. Skill at Counter-Strike and other fast games is good too. League is also in training. Goal is to generalize across all games."
