Chatbots

Overview​

Chatbots are one of the most popular use-cases for LLMs. The core features of chatbots are that they can have long-running, stateful conversations and can answer user questions using relevant information.

Architectures​

Designing a chatbot involves considering various techniques with different benefits and tradeoffs depending on what sorts of questions you expect it to handle.

For example, chatbots commonly use retrieval-augmented generation, or RAG, over private data to better answer domain-specific questions. You also might choose to route between multiple data sources to ensure it only uses the most topical context for final question answering, or choose to use a more specialized type of chat history or memory than just passing messages back and forth.
