Memory

Stored information a system can retrieve and reuse later in a workflow.

Definition

Memory, in AI systems, is information a model or agent stores so it can be retrieved and reused later rather than re-derived each time. It may live in the prompt itself, in an external store queried by retrieval, or in structured records of past events and facts. Memory lets a system carry state across turns and sessions, which is essential for any task longer than one exchange.
