@raveharpaz do you want to add any tests? Seems scary to update core functionality with no tests.

---

Separately, would you be interested in publishing an Oracle OSS integration package (e.g., langchain-oracle or langchain-oci)? We've published a walkthrough on this process here:

https://python.langchain.com/docs/contributing/how_to/integrations/

We are encouraging contributors of LangChain integrations to go this route. This way we don't have to be in the loop for reviews, you're able to properly integration test the model, and you have control over versioning.

Docs would continue to be maintained in the langchain repo.

Let me know what you think!

Hi @ccurme , thanks for the feedback

1. new features have been thoroughly tested with our services/models. these tests cannot be shared due to confidential connection details, and the existing unit tests (based on mocked io) cover the essentials.
2. Yes, the package version is in the works and should be available soon
