Data is converted into embeddings — numerical representations of meaning — stored in a vector database, and agents can search it to retrieve only relevant information. This pattern enables agents to answer questions about documents and recall long-term facts even when the context window is full. ## Full article daily.dev links to this article rather than hosting it.
