How Physical Intelligence runs remote, real-time, robotic inference on Modal.
Physical Intelligence (Pi) is building a general-purpose robotic intelligence system capable of operating any robot across any task. Their core model—a Visual-Language-Action (VLA) architecture—takes visual observations, natural-language instructions, and the robot’s proprioceptive state, then outputs motor commands for the next fraction of a second. Every arm movement in their system flows through this closed loop of continuous inference. To evaluate progress, Pi doesn’t just rely on simulation. Every model revision must be validated on real robots performing real tasks. That means…
