Embeddings
An embedding is a list of numbers, learned during training, that represents a piece of text so that similar meanings get similar numbers. Embeddings let AI find material by meaning rather than by matching words, but they record that ideas are associated, not how they are related.
Retrieval augmented generation
A technique that improves a language model's answers by retrieving relevant passages from your own documents and adding them to the prompt, so the model answers from sources instead of from memory alone.
Single-hop reasoning
Answering a question in one step, by retrieving the passages most similar to it and generating a response from them. It's the default pattern in RAG systems, reliable when the answer sits in one place and weak when it has to be assembled from several.
Vector database
A database that stores embeddings, so that it can find content by meaning instead of by matching words. It's the storage layer behind most RAG systems.
