What is OpenVINO toolkit?

OpenVINO™ is an open-source toolkit for optimizing and deploying AI inference.

  • Boost deep learning performance in computer vision, automatic speech recognition, natural language processing and other common tasks
  • Use models trained with popular frameworks like TensorFlow, PyTorch and more
  • Reduce resource demands and efficiently deploy on a range of Intel® platforms from edge to cloud

This open-source version includes several components: namely Model Optimizer, OpenVINO™ Runtime, Post-Training Optimization Tool, as well as CPU, GPU, MYRIAD, multi device and heterogeneous plugins to accelerate deep learning inference on Intel® CPUs and Intel® Processor Graphics. It supports pre-trained models from Open Model Zoo, along with 100+ open source and public models in popular formats such as TensorFlow, ONNX, PaddlePaddle, MXNet, Caffe, Kaldi.

Components

  • OpenVINO™ Runtime - is a set of C++ libraries with C and Python bindings providing a common API to deliver inference solutions on the platform of your choice.
    • core - provides the base API for model representation and modification.
    • inference - provides an API to infer models on the device.
    • transformations - contains the set of common transformations which are used in OpenVINO plugins.
    • low precision transformations - contains the set of transformations that are used in low precision models
    • bindings - contains all available OpenVINO bindings which are maintained by the OpenVINO team.
      • c - C API for OpenVINO™ Runtime
      • python - Python API for OpenVINO™ Runtime
  • Plugins - contains OpenVINO plugins which are maintained in open-source by the OpenVINO team. For more information, take a look at the list of supported devices.
  • Frontends - contains available OpenVINO frontends that allow reading models from the native framework format.
  • Model Optimizer - is a cross-platform command-line tool that facilitates the transition between training and deployment environments, performs static model analysis, and adjusts deep learning models for optimal execution on end-point target devices.
  • Post-Training Optimization Tool - is designed to accelerate the inference of deep learning models by applying special methods without model retraining or fine-tuning, for example, post-training 8-bit quantization.
  • Samples - applications in C, C++ and Python languages that show basic OpenVINO use cases.
