ONNX

ONNX (Open Neural Network Exchange) is an open-source format: it standardizes machine learning models, ensuring interoperability across all major frameworks and deployment hardware.

ONNX delivers critical model portability. It defines a standardized computation graph and operator set, allowing developers to train a model in one framework (e.g., PyTorch or TensorFlow) and deploy it seamlessly using a different runtime. This eliminates framework lock-in and optimizes production performance. Founded in 2017 by key industry players (AWS, Microsoft, Facebook), ONNX now boasts contributions from companies like NVIDIA, Intel, and Qualcomm. The high-performance ONNX Runtime, for example, powers AI inference across major Microsoft products, including Windows, Office, and Azure Cognitive Services, demonstrating its enterprise-grade efficiency and cross-platform capability (cloud, edge, mobile).
