Beam

freemium

4.2 / 5.0

Beam is a serverless GPU cloud platform that lets Python developers deploy AI functions and machine learning models as scalable APIs in seconds, without managing any infrastructure. Developers annotate their Python functions with Beam decorators specifying GPU requirements, and Beam handles provisioning, scaling, and billing automatically on a pay-per-second basis. It is optimised for fast iteration cycles, making it popular for deploying fine-tuned models, running inference pipelines, and building AI backends.

Best for: Python developers who need to quickly deploy AI models and inference pipelines as APIs without any infrastructure management.
