Thanks @kunal-vaishnavi -- can you trigger a re-run of the checks? I don't think that this MacOS failure is related to this changeset. |

@kunal-vaishnavi -- any insight into why this MacOS build is failing? I also see similar failures in another PR: #1900 I don't think it's related to these changesets, so perhaps there is some instability in MacOS builds currently? |

I am still investigating. The CI failure is in the latest commit on the main branch and in an older commit as well. |

@kunal-vaishnavi -- I rebased against latest main that included MacOS fixes, and pipeline is passing now. |

…coder are stateful. (#1857) This will mainly be used to support EPCtx-wrapped OpenVINO IR's -- the same set of models that are compatible with OpenVINO GenAI. In this case, unlike the default pipeline, the encoder doesn't pull in KV cross projection -- it only outputs encoder_hidden_states. For the decoder portion of the pipeline, the cross & self KV cache tensors are managed internal to the model (attached to the session).
