🗣️Retrieval-Augmented Generation (RAG)

Combining LLMs with external knowledge retrieval. Instead of relying solely on training data, RAG retrieves relevant documents and passes them to the LLM, reducing hallucinations and adding current information. Contextual retrieval prepends document context to each chunk before embedding, a simple fix for chunks that lose their meaning alone.
