Building the Agent Cloud: Introducing Baseten Sandboxes

Baseten introduced Sandboxes, stateful agent runtimes built on microVMs that snapshot filesystem, memory, and running processes on disconnect and resume in about 25 ms, with boot from standby in 25 ms and scaling to thousands of sandboxes within seconds. They are the first piece of a planned agent cloud, to be followed by Agent Drive (a shared distributed filesystem) and Agent Proxy (external network control with credential injection, permissions, and audit logging). Sandboxes are free to run until November 16th.
