Semantic Memory — AI Glossary
Memory of generalized facts and relationships extracted from prior interactions, stored in a knowledge graph or structured store.
Overview
Used to give agents domain knowledge that persists across episodes without re-stuffing the prompt each time. Contrast with episodic memory (event-level) and working memory (current context window).

Commonly confused with
The counterpart to episodic memory: generalised facts rather than a record of events. It differs from a knowledge base in provenance — a knowledge base is authored and reviewed, whereas these facts were extracted by a model from conversation and inherit that model's errors. Treat entries as claims with a source, not as ground truth.
