Yeah I've heard of it but never used it. Looks like they have a backend/runtime for ONNX models as well (https://pypi.org/project/onnxruntime-openvino/) neat!

ONNX really is the universal format. If you can get your model exported to ONNX, running it on various platforms becomes much easier.*

*as long as every hardware platform supports the ops you use in your network and you're not doing anything too fancy/custom :P
