Agent Longevity vs Zep
Zep is an enterprise context platform built on its open-source Graphiti temporal knowledge-graph engine: it ingests chat and business data into per-user, timestamped fact graphs with automatic fact invalidation, served with strong governance (access controls, retention, audit) at low latency. Its enterprise posture is a genuine strength — audited security certifications and in-customer-VPC deployment have landed it large regulated-industry customers.
What Zep does well — temporal knowledge-graph memory
- A temporal knowledge graph that tracks when a fact became true and when it was superseded
- Sub-200ms hot-path context retrieval for live agent runtimes
- Audited enterprise security certifications plus deploy-in-your-VPC options
- An open-source, self-hostable core engine with a large community
- Fine-grained memory governance: access controls, retention policy, and audit on reads/writes
Capability by capability
| Capability | Zep | Agent Longevity◀ us |
|---|---|---|
Temporal fact graph (what was true, and when) Timestamped fact validity windows with automatic invalidation as facts change. ALI captures point-in-time cognitive state, not a queryable fact timeline. | ||
Durable on-chain agent identity An ALI Passport survives any model swap, provider outage, or platform migration. | ||
Content-sealed cognitive-state snapshots A Cortex Crystal seals identity, prompts, configuration, and behavioral fingerprint — not just a chat transcript. | ||
Cryptographic verifiability of state Every crystal carries a content fingerprint anchored on-chain — provably unaltered. | ||
Verified restore Restore a prior state after a conflict check, with the fingerprint re-verified before it goes live. | ||
Verifiable erasure Revocation deletes your content and issues a signed, verifiable erasure receipt — not a status flag. | ||
Autonomous agent self-registration & self-pay An agent can discover ALI via its published manifests and pay in stablecoin with no human in the loop. |

Zep for context. ALI for the agent's continuity.
Zep answers "what does this agent know, and when did it learn it." ALI answers a different question: "is this still the same agent, and can I prove what it was before?" Run Zep as your live context layer; let ALI seal the identity, configuration, and memory-reference state that sits around it into a tamper-evident Cortex Crystal, restorable after any migration.
Keep Zep. Add a durable self.
