Effortlessly scale your most complex workloads
Ray is an open-source unified compute framework that makes it easy to scale AI and Python workloads — from reinforcement learning to deep learning to tuning, and model serving. Learn more about Ray’s rich set of libraries and integrations.
Deep learning
Accelerate your PyTorch and Tensorflow workload with a more resource-efficient and flexible distributed execution framework powered by Ray.
Hyperparameter tuning
Accelerate your hyperparameter search workloads with Ray Tune. Find the best model and reduce training costs by using the latest optimization algorithms.
Model serving
Deploy your machine learning models at scale with Ray Serve, a Python-first and framework agnostic model serving framework.
Reinforcement learning
Scale reinforcement learning (RL) with RLlib, a framework-agnostic RL library that ships with 30+ cutting-edge RL algorithms including A3C, DQN, and PPO.
General Python apps
Easily build out scalable, distributed systems in Python with simple and composable primitives in Ray Core.
Data processing
Scale data loading, writing, conversions, and transformations in Python with Ray Datasets.
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
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.
