The Open Neural Network Exchange (ONNX) []
is an Open-source software, open-source artificial intelligence ecosystem
of technology companies and research organizations that establish open standards for representing machine learning algorithms and software tools to promote innovation and collaboration in the AI sector. ONNX is available on

In November 2019 ONNX was accepted as graduate project in Linux Foundation AI.
In October 2020 Zetane Systems became a member of the ONNX ecosystem.
Intent
The initiative targets:
Framework interoperability
Allow developers to more easily move between frameworks, some of which may be more desirable for specific phases of the development process, such as fast training, network architecture flexibility or inferencing on mobile devices.
Shared optimization
Allow hardware vendors and others to improve the performance of
artificial neural network
Artificial neural networks (ANNs), usually simply called neural networks (NNs) or neural nets, are computing systems inspired by the biological neural networks that constitute animal brains.
An ANN is based on a collection of connected unit ...
s of multiple frameworks at once by targeting the ONNX representation.
Contents
ONNX provides definitions of an extensible computation graph model, built-in operators and standard
data types, focused on inferencing (evaluation).
Each computation
dataflow graph is a list of nodes that form an
acyclic graph. Nodes have inputs and outputs. Each node is a call to an operator. Metadata documents the graph. Built-in operators are to be available on each ONNX-supporting framework.
