The Open Neural Network Exchange (ONNX) format, released in 2017, is a portable file format for describing machine learning models. ONNX models are self-contained files (.onnx) that can be easily exported from all the major training frameworks and are supported by many hardware architectures and operating systems enabling improved efficiency at inference time. The ONNX Runtime in particular, developed in the open by Microsoft, is cross-platform and high performance with a simple API enabling you to run inference on any ONNX model exactly where you need it: VM in cloud, VM on-prem, phone, tablet, IoT device, you name it!
