What is Ray Serve?
Ray Serve is a scalable model serving library for building online inference applications, offering features like model composition, model multiplexing, and built-in autoscaling.
Because Ray Serve is framework-agnostic, you can use a single toolkit to serve everything from deep learning models built with any ML framework, including PyTorch, TensorFlow, and other popular frameworks.
Plus, Ray Serve has several features and performance optimizations for serving LLMs such as response streaming, dynamic request batching, multi-node/multi-GPU serving, and more.

Ray Serve Feature Highlights
Model Composition
Integrate multiple ML models with separate resource requirements and auto-scaling needs within one deployment. Orchestrate processing workflows at scale with Ray Serve.
