Overview

ONNX Runtime executes models exported from PyTorch, TensorFlow and Keras, TensorFlow Lite, scikit-learn and other frameworks through the ONNX format. Hardware vendors plug in execution providers such as CUDA and DirectML, which makes it a common portability layer across edge silicon.

Typical use cases

  • Cross-vendor edge deployment
  • AI PC applications
  • Server and device parity

Deployment environment

Edge device, client PC or server
