Summary

Modal is presented as a virtual computer rather than simply an AI infrastructure platform, cloud provider, or inference service, running programs across resources supplied by many cloud providers. Its architecture is compared to that of a conventional computer: containers execute functions, sandboxes, or HTTP servers; container memory and disks support active workloads; object storage provides durable capacity; and caching layers, volumes, and ephemeral disks balance speed and storage scale. Modal converts container image definitions into reusable filesystems, similarly to how conventional systems compile source code into shared executable components, while its runtime schedules and isolates containers across underlying infrastructure. Its Input/Output Plane and Routing Plane handle function, sandbox, and HTTP-server communications, with Tunnels offering more direct TCP or UDP connections for performance-sensitive workloads. By virtualizing compute resources at a higher level than individual cloud platforms, Modal aims to aggregate, multiplex, and isolate demand across clouds while making large-scale compute more accessible to engineering teams.
