Ray is a unified framework that makes building machine learning platforms easier than ever by providing scalable libraries and tools for Python developers to build and scale their applications. It has an ecosystem of standalone libraries that can be used to address some of the key features required in modern AI applications, including bridging the gap between development and production, easy ML scaling, and ecosystem integration. Ray is particularly useful for teams struggling with managing the machine learning lifecycle, as it provides a suite of scalable machine learning libraries that can be used and composed like any other Python library, simplifying the gap between ML development and production. Its ability to scale, distribute computing, and support various frameworks such as XGBoost, PyTorch, and TensorFlow makes it an attractive choice for developers building ML platforms and components.
