This sample 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-4o-mini), and Azure AI Search for data indexing and retrieval.
The repo includes sample data so it's ready to try end to end. In this sample application we use a fictitious company called Contoso Real Estate, and the experience allows its customers to ask support questions about the usage of its products. The sample data includes a set of documents that describe its terms of service, privacy policy and a support guide.
The application is made from multiple components, including:
- **Search service**: the backend service that provides the search and retrieval capabilities.
- **Indexer service**: the service that indexes the data and creates the search indexes.
- **Web app**: the frontend web application that provides the user interface and orchestrates the interaction between the user and the backend services.
## Features
- Chat and Q&A interfaces
- Explores various options to help users evaluate the trustworthiness of responses with citations, tracking of source content, etc.
- Shows possible approaches for data preparation, prompt construction, and orchestration of interaction between model (ChatGPT) and retriever (Azure AI Search)
- Settings directly in the UX to tweak the behavior and experiment with options
- Optional performance tracing and monitoring with Application Insights
