A guide details how to build a Retrieval-Augmented Generation (RAG) chatbot over a weekend using PostgreSQL with the pgvector extension, FastAPI, and Anthropic's Claude model. The process involves embedding user questions and documents using a separate embedding model, storing these embeddings in PostgreSQL, and then using Claude to generate answers based on the retrieved context. The guide highlights that Claude does not offer its own embeddings API, necessitating the use of third-party services like Voyage AI or OpenAI for this crucial step. AI
