A 36-second explainer on the standard pattern for agent long-term memory: convert your data into embeddings — numerical representations of meaning — store them in a vector database, and give the agent a search tool so it retrieves only the relevant pieces for the task at hand. Tech With Tim names this as RAG (retrieval-augmented generation) and frames it as the answer to a specific problem — the context window is already full of the current conversation, so documents, Q&As and long-term facts have to live somewhere the agent can query on demand.
