What is Modal?

Modal is a serverless platform that lets you run GPU-accelerated and batch Python workloads without managing any infrastructure. It abstracts away servers, containers, and scaling, letting developers focus on code. With native Python decorators, you can define functions that automatically execute on CPUs or GPUs, pay only for the exact compute time used, and monitor performance through an integrated dashboard.
