Beam is an innovative serverless GPU platform tailored for developers to effortlessly deploy AI workloads with minimal setup and swift iteration. It allows for the execution of custom models with container start times of less than a second and eliminates idle GPU costs, meaning users can focus on their code while Beam takes care of the underlying infrastructure. With the ability to launch containers in just 200 milliseconds through a specialized runc runtime, it enhances parallelization and concurrency by distributing workloads across numerous containers. Beam prioritizes an exceptional developer experience, offering features such as hot-reloading, webhooks, and job scheduling, while also supporting workloads that scale to zero by default. Additionally, it presents various volume storage solutions and GPU capabilities, enabling users to run on Beam's cloud with powerful GPUs like the 4090s and H100s or even utilize their own hardware. The platform streamlines Python-native deployment, eliminating the need for YAML or configuration files, ultimately making it a versatile choice for modern AI development. Furthermore, Beam's architecture ensures that developers can rapidly iterate and adapt their models, fostering innovation in AI applications.
