Open Inference Protocol Specification

The Open Inference Protocol(OIP) specification defines a standard protocol for performing machine learning model inference across serving runtimes for different ML frameworks. The protocol facilitates the implementation of a standardized and high performance data plane, promoting interoperability among model serving runtimes. The specification enables the creation of cohesive inference experience, empowering the development of versatile client or benchmarking tools that can work with all supported serving runtimes.
