Embeddings are the technical foundation for making RAG (AI with your data) work, transforming text into numbers that represent meaning. Without them, your AI is dumb or too expensive. This practical guide with Python and sentence-transformers shows how to implement semantic search, solve synonym problems, and understand why they're essential for building intelligent and efficient chatbots.
