Powered by Ray

Companies of all sizes and stripes are scaling their most challenging problems with Ray. Recommendation engines, ecosystem restoration, large-scale earth science, automated traffic monitoring, flying boats — these are just a few of the many use cases that engineers, scientists and researchers like you are tackling with Ray.



Uber consolidated and optimized their end-to-end deep learning workflows by using Ray as the distributed backend for their machine learning platform. Ray's flexibility, extensibility and low maintenance overhead made Ray a clear winner over alternatives.
