What is Modal?

Modal lets you run Python functions in the cloud as serverless jobs with a single decorator. It handles container builds, GPU provisioning, scaling, and scheduling automatically — designed for ML engineers who want cloud power without DevOps.

Our Review

Modal has the most elegant developer experience for cloud ML workloads. The decorator-based API means you can run GPU-accelerated code in the cloud with almost no configuration change from local code. For batch inference and training jobs, it's often the most productive choice.
