Ray

Ray is an open-source unified compute framework, stewarded by Anyscale, that scales Python and AI workloads from a laptop to a cluster. It consists of Ray Core (a distributed runtime) and a set of AI libraries (Ray Train, Ray Data, Ray Tune, Ray Serve, RLlib) for training, batch inference, hyperparameter search, and model serving. Ray clusters expose a Dashboard and Jobs REST API on the head node (default port 8265) for submitting jobs, inspecting actors and tasks, and serving deployed applications via Ray Serve HTTP endpoints.

Ray publishes 2 APIs on the APIs.io network: Jobs API and Version API. Tagged areas include Distributed Computing, Machine Learning, AI Infrastructure, Python, and Model Serving.

Ray’s developer surface includes documentation, engineering blog, and 10 more developer resources.
