About:
ONNX (Open Neural Network Exchange) is an open-source format for representing machine learning models. It enables developers to train models in various frameworks like PyTorch and TensorFlow, then export them for inference in different environments. This interoperability prevents vendor lock-in and streamlines the deployment of AI models across diverse hardware platforms.
Key Features:
  • Cross-framework interoperability
  • Standardized model representation
  • Optimized for inference
  • Extensible computation graph
Use Cases:
  • Deploying trained models to production environments
  • Transferring models between different ML frameworks
  • Running inference on edge devices and hardware accelerators
Alternatives:
  • TensorFlow SavedModel – Framework-specific format, whereas ONNX provides broader cross-framework compatibility
  • PMML – Older standard focused on traditional ML, less suited for deep learning models than ONNX
