What Modal is
Modal is a serverless runtime for Python workloads built on gVisor, with its own scheduler and years of aggressive container-start engineering behind it. The Sandbox API exposes that infrastructure for running untrusted or agent-generated code, including on GPUs. It is the strongest option here if the sandbox needs to sit next to real ML work, and an awkward fit if you just want a plain Linux box.
