Episodic Memory (Agent)

Reviewed 9 April 2026 Canonical definition

Episodic memory in an AI agent is the retention of specific past events — interactions, completed tasks, or decision outcomes — that the agent can retrieve and reason about in future sessions. Unlike semantic memory, which stores general facts, episodic memory stores experiences with temporal context. It enables agents to personalise behaviour based on history but requires careful governance of what is stored and for how long.
