Build Your Own Background Agent: The infra that scales it to millions

A quick tour of Modal's serverless AI infrastructure — inference, training, batch jobs, sandboxes — followed by a live build. You'll see Modal Sandboxes running background agents and safely executing untrusted code, walk through GPU availability and enterprise-readiness considerations, and follow a hands-on tutorial that builds a background agent on Modal from scratch: autoscaling functions, running Claude Code inside a Modal Sandbox, and wiring it all into a service that scales from one user to millions.
