What is Modal?

Modal is a serverless compute platform for running AI/ML workloads in the cloud with minimal infrastructure overhead. The platform enables developers to run Python functions at scale, from data processing to model training and inference. Modal provides GPU access, auto-scaling, and pay-per-second billing, making it cost-effective for variable workloads. The platform is particularly popular for AI applications requiring GPU compute without the complexity of cloud infrastructure management. Modal offers a generous free tier and simple pricing that scales with usage.
