Product Description

Zep is a novel AI agent memory layer service that dynamically synthesizes unstructured conversational data and structured business data through its core component, Graphiti (an open-source temporal knowledge graph engine), while maintaining historical relationships. Unlike simple vector stores, Zep constructs temporal knowledge graphs that not only know "what you said" but also "when you said it" and "how it relates to the context before and after." In the DMR benchmark, Zep outperforms state-of-the-art systems like MemGPT.

Core Features/Characteristics

  • Temporal Knowledge Graph: Each memory is time-anchored, tracking changes in facts over time
  • Graphiti Engine: Open-source temporal knowledge graph engine
  • Context Assembly: Connects data sources to build a unified user context graph, assembling the correct context for agents
  • Entity Types: Developers can precisely define and recall domain-specific information
  • Custom Extraction Instructions: Attribute-level search filtering, exclusion filtering, Webhook support
  • Hybrid Data Processing: Handles both unstructured conversational and structured business data simultaneously
  • Cross-Session Information Synthesis: Capable of synthesizing information across multiple sessions

Performance

  • Accuracy improvement of up to 18.5% (compared to baseline implementations)
  • Response latency reduced by 90%
  • Excels in enterprise-critical tasks such as cross-session information synthesis and long-term context maintenance

Business Model

  • Graphiti Open Source: Core graph engine is open-source
  • Zep Cloud: Hosted memory service
  • Free Tier: Basic features
  • Pro: Additional features and quotas
  • Enterprise: Enterprise-level deployment and support

Relationship with OpenClaw Ecosystem

Zep's temporal knowledge graph architecture provides OpenClaw with an advanced memory management solution. For personal AI agents, tracking changes in user preferences and facts over time is crucial—for example, a user who previously worked in Shanghai but later moved to Beijing. Zep's Graphiti engine can help OpenClaw build a time-aware user knowledge graph, offering more accurate personalized services.
