Anatomy of Persistent Memory's 3 Layers: Comparing ContextNest, Mem0 and Zep
Summary
The article argues that production-grade AI agents require a three-layer persistent memory stack (Zep for session logs, Mem0 for personalization, ContextNest for governed corporate knowledge). It explains each layer's role, governance, and learning mechanisms, and advocates deploying all three together to avoid hallucinations and ensure deterministic, auditable context for LLMs. The piece also offers FAQs, comparisons, and deployment guidance.
