 This repo contains all the work done to develop demos on the integration between [**LangChain**](https://www.langchain.com/) and Oracle [**OCI GenAI**](https://www.oracle.com/artificial-intelligence/generative-ai/large-language-models/) Service.
 
 ## OCI Generative AI Service is in Limited Availability

-Availability**.

-It means that:
-* to test this code you need to apply for the LA
-* during the LA there could be breaking changes, in the OCI SDK or in the signature of the service.
-* integration with LangChain will be published officially. Plans are that it will be published when GenAI Service will be GA.
-
-I'll try to keep the code updated.
