Modal powers real-time inference for Physical Intelligence robots

Physical Intelligence (Pi) runs its Visual-Language-Action robot models on Modal, adding only ~10-15ms of network overhead. Pi worked with Modal to build a QUIC-based portal over UDP with automatic NAT traversal, replacing TCP Tunnels to avoid request-response stalls in the robot control loop. Checkpoints stored in Modal Volumes load in under 30 seconds, and region-pinned deployments keep inference close to robots.
