The 7 Types of Agent Memory: A Technical Guide
Large language models are stateless by default, requiring memory mechanisms to retain context across interactions. The seven types of agent memory—working, semantic, episodic, procedural, retrieval, parametric, and prospective—categorize memory by form and duration, enabling agents to plan, learn, and act over time. Each type serves distinct use cases, from storing user preferences to scheduling future goals, and together they form a comprehensive system for long-horizon, context-aware AI agents.
