Thanks for the contribution @OpenVINO-dev-contest -- haven't taken a closer look yet, but just wondering would LogProbs be available for this LLM integration?

Is the class name HuggingFace_LLM intended, or should it be something like OpenVino_LLM?

[Javtor]

General comment: Since OpenVINOLLM is very similar to HuggingFaceLLM (only DEFAULT_HUGGINGFACE_MODEL, the constructor, and class_name change) I would much prefer subclassing to avoid code-duplication, and changing the Pydantic fields default values and constructor as needed.

Pydantic

This is great idea, and thanks for your review, have updated it accordingly.

LogProbs

Hi since this implementation is a subclass of huggingface LLM, its functions will be aligned with HF.

[Javtor]

Thanks for the change!
There seems to be a dependency conflict with the huggingface_hub version. This pyproject.toml requires huggingface_hub<0.23.0 and >=0.22.2, but the one from llama-index-llms-huggingface requires it to be <0.21.0 and >=0.20.3

dependency

removed the conflict dependency to align with HF.
