Docs Chat is a document Q&A chatbot that demonstrates basic retrieval-augmented generation (RAG) with large language models. At its core, it leverages OpenAI's language models to provide intelligent responses to user queries. It also has the ability to incorporate relevant context from user-provided documents into the conversation. By retrieving and including semantically similar document passages in the prompts, the system can provide more accurate and up-to-date responses. This approach enables a wide range of applications, from querying proprietary business documents to accessing current information beyond the LLM's training cutoff date.
