Existing deployments may still lack authentication.\n\n**Zep.** Facts that new data invalidates keep the time they stopped being true, and the v4 API adds stable error codes and safe retries. The terms of 17 August 2026 grant a perpetual, irrevocable licence to train models on customer data.\n\n## Before you call either\n\n### AI Memory\n\n1. Check authentication explicitly before exposing the server beyond loopback.\n2. Exclude secrets and sensitive repositories from memory capture.\n3. Back up memory and follow the version 3 migration guide.\n\n### Zep\n\n1. Use the 4.0 SDKs and store the UUID each create call returns. v4 calls take Zep UUIDs, not your own user or thread IDs\n2. Set `return_context` when adding messages to skip a second round trip\n3. Keep episodes short. Every 350 bytes past the first costs another credit\n4. Branch on `error.code`. On a 429, wait for Retry-After with jitter. Free accounts over quota drop to 5 requests a minute\n5. Send an `Idempotency-Key` on any create call your code may repeat, and expect a delay after an add (202 Accepted) before new facts show up in search\n\n## Questions\n\n### Which is better for AI agents, AI Memory or Zep?\n\nZep scores 73.9 (BB) on agent readiness against AI Memory's 55.7 (C), and leads in 6 of 7 scored categories. AI Memory leads on payments \u0026 pricing.\n\n### Do AI Memory and Zep need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call AI Memory and Zep without installing anything?\n\nAI Memory runs on your own machine, with no hosted endpoint listed. Zep has a hosted endpoint at https://api.getzep.com/api/v4.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/ai-memory-vs-zep.json, and with the fewest tokens: https://www.anchorterminal.com/compare/ai-memory-vs-zep.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"ai-memory\", \"b\": \"zep\"}`.
