OpenVINO is an open-source software toolkit for optimizing and deploying deep learning models. It enables programmers to develop scalable and efficient AI solutions with relatively few lines of code. The supported models come from several existing frameworks and support different categories, including large language models, computer vision, and generative AI.
Actively developed by Intel, it prioritizes high-performance inference on Intel hardware but also supports ARM/ARM64 processors[2] and encourages contributors to add new devices to the portfolio.
OpenVINO is cross-platform and free for use under Apache License 2.0.[3]
Overview
The high level pipeline of OpenVINO consists of two parts: generate IR (Intermediate Representation) files via Model Optimizer using your trained model or public one and execute inference on Inference Engine on specified devices.
OpenVINO has different sample types: classification, object detection, style transfer, speech recognition, etc. It is possible to try inference on public models. There are a variety of models for tasks, such as:
- classification
- segmentation
- object detection
- face recognition
- human pose estimation
- monocular depth estimation
- image inpainting
- style transfer
- action recognition
- colorization
OpenVINO model format
OpenVINO IR[4] is the default format used to run inference. It is saved as a set of two files, *.bin and *.xml, containing weights and topology, respectively. It is obtained by converting a model from one of the supported frameworks, using the application's API or a dedicated converter.
Models of the supported formats may also be used for inference directly, without prior conversion to OpenVINO IR. Such an approach is more convenient but offers fewer optimization options and lower performance, since the conversion is performed automatically before inference.
The supported model formats are:[5]
- PyTorch
- TensorFlow
- TensorFlow Lite
- ONNX (including formats that may be serialized to ONNX)
- PaddlePaddle
Programming language
OpenVINO is written in C++ and Python.
OS support
OpenVINO runs on the following desktop operation systems: Windows, Linux and MacOS.[citation needed]
