 [Zep's](https://www.getzep.com) context infrastructure for AI agents. Zep manages context graphs at scale, providing
 governed, low-latency context retrieval and assembly for production agent deployments.
 
+Under the hood, Zep is powered by a proprietary graph database — the
+[Context Graph Engine](https://www.getzep.com/platform/context-graph-engine/) — built for millions of context graphs
+with low-latency retrieval, so production deployments don't require a separate third-party graph database.
