ONNX Model Format

ONNX (Open Neural Network Exchange) is an open-source format for representing machine learning models. It's framework-agnostic: train in PyTorch, convert to ONNX, and run on any platform (mobile, web, edge, cloud) using ONNX Runtime. The format defines a standard computation graph: inputs → operators (Conv, ReLU, etc.) → outputs. The value: train once, deploy anywhere. No vendor lock-in. Enables cross-platform inference, model optimization, and industry standardization.
