Ray is an open-source AI compute engine for distributed Python workloads such as training, batch inference, hyperparameter tuning, and serving. Anyscale, the company behind Ray, offers hosted Ray with credits, but Ray itself is the framework orchestrating clusters on any accelerator.
ML engineers scaling Python AI jobs from laptops to clusters who need unified distributed training, tuning, and serving.
Managed Anyscale hosting bills compute separately; ray.io focuses on the open framework rather than listing monthly seat prices.
Ray.io presents Ray as the center of large-scale AI platforms, unifying development and production distributed workloads across accelerators.

Ray is an open-source framework; Anyscale marketing offers $100 credit to try hosted Ray but Ray itself has no seat fee.
CerebriumCerebrium is a serverless GPU platform for deploying real-time AI workloads such as voice agents, video models, and LLMs with sub-second cold starts and elastic scaling. Teams run Python apps on managed GPUs across multiple regions and pay for compute by the second rather than reserved capacity.
