 This repo is the java conversion of the well known [ChatGPT + Enterprise data code sample](https://github.com/Azure-Samples/azure-search-openai-demo) originally written in python.
 It demonstrates a few approaches for creating ChatGPT-like experiences over your own data using the Retrieval Augmented Generation pattern. It uses Azure OpenAI Service to access the ChatGPT model (gpt-35-turbo), and Azure Cognitive Search for data indexing and retrieval.
