+Using this package, you can augment the model analysis & explanation feature
+on top of the existing OpenVINO inference pipeline with a few lines of code.

+> * [OpenVINO IR branch insertion not working for models converted directly from torch models with OVC (#26)](https://github.com/openvinotoolkit/openvino_xai/issues/26)
+> A simple workaround is to convert Torch models to ONNX models and then convert to OpenVINO models to feed to OpenVINO XAI. Please refer to [the code example](openvino_xai/utils/model_export.py).

 > **_NOTE:_**  GenAI / LLMs would be also supported incrementally in the upcoming releases.
