Ray is a high-performance distributed computing framework that enables companies to scale machine learning training workloads by up to 10x compared to existing tools like Celery, AWS Batch, SageMaker, Vertex AI, Dask, and more. Ray's flexible scheduling and unification capabilities make it an ideal solution for training many models, as demonstrated by companies like Instacart, Ecommerce, and B2B analytics firms that have seen order-of-magnitude performance and scalability wins using the framework. By leveraging Ray's built-in libraries and resource-based scheduling, developers can efficiently train multiple models in parallel, reducing training times and improving overall performance. Additionally, Ray integrates with other machine learning ecosystems and frameworks, including PyTorch, TensorFlow, Horovod, XGBoost, Scikit-learn, Hugging Face, and LightGBM, making it a versatile solution for building scalable machine learning workflows.
