Complete Context Engineering vs. Basic Memory Storage

Move beyond basic memory storage. Zep provides complete context engineering that combines agent memory, Graph RAG, and automated context assembly with temporal knowledge graphs and business data integration.

Zep: Complete Context Engineering

  • •Agent Memory: Temporal knowledge graphs that track fact evolution over time
  • •Graph RAG: Semantic, keyword, and graph traversal search combined
  • •Automated context assembly: Relevant context delivered to LLMs automatically
  • •Custom entity schemas: Domain-specific entities and relationships
  • •Enterprise data ingestion: Native JSON, text, and message processing
  • •Multi-level memory: User, group, and session-level graphs

Mem0: Basic Memory Storage

  • •Three-store system: Graph (paid add-on), vector, and key-value stores
  • •Basic relationships: Simple entity connections via custom prompts
  • •Mutated memories: In-place updates with no versioning or history
  • •Conversation-focused: Chat history and user preferences
  • •Manual retrieval: No automated context assembly

Far More Accurate, Faster, More Efficient

Zep leads on the LoCoMo benchmark with single-shot retrieval. No slow agentic loops. Multiple configurations let you optimize for accuracy, latency, and token efficiency.
