Build a RAG System for an AI Chatbot
An AI engineer is tasked with creating a knowledgeable chatbot for customer support. They use a Postgres database with the pgvector extension to store vector embeddings of their entire knowledge base. When a user asks a question, the system first converts the query into a vector, then uses Postgres to perform a similarity search to find the most relevant document chunks. These chunks are then fed to a Large Language Model (LLM) as context, allowing the chatbot to provide accurate, context-aware answers based on internal documentation, significantly reducing hallucinations.
