This is much broader than ONNX its closer to ONNX Runtime + ONNX but it has some important advantages. StableHLO is the IR already supported by most HW accelerators including Inferentia/Trainium and TPU.

Much of this code is not "new" in the sense that much of the OpenXLA effort has been extracting the existing XLA representations and compiler from the TensorFlow codebase so it can be more modularly used by the ecosystem (including PyTorch).

A better frame is TensorFlow exporting its stable representation that many vendors have already built around, more than a "new" standard.
