ONNX
ONNX.ai is an open source standard for machine learning model interoperability, enabling developers to train models in one framework (like PyTorch or TensorFlow) and deploy them across diverse platforms using a unified format. Its purpose is to streamline AI development and deployment by promoting framework-agnostic model sharing, optimizing performance across hardware, and reducing vendor lock-in through a consistent, extensible representation of neural networks and traditional ML algorithms
