The Open Neural Network Exchange is an 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.
Many people are working on great tools, but developers are often locked in to one framework or ecosystem. ONNX is the first step in enabling more of these tools to work together by allowing them to share models.

ONNX’s goal is to make it possible for developers to use the right combinations of tools for their project. It wants everyone to be able to take AI from research to reality as quickly as possible.
ONNX is available on GitHub.
