Single-pass retrieval (one call, no agentic loops).\n\nWhat changed: - Single-pass ADD-only extraction -- one LLM call, no UPDATE/DELETE. Memories accumulate; nothing is overwritten. - Agent-generated facts are first-class -- when an agent confirms an action, that information is now stored with equal weight. - Entity linking -- entities are extracted, embedded, and linked across memories for retrieval boosting. - Multi-signal retrieval -- semantic, BM25 keyword, and entity matching scored in parallel and fused. - Temporal Reasoning -- time-aware…\n\nSee the migration guide for upgrade instructions. The evaluation framework is open-sourced so anyone can reproduce the numbers.\n\nmem0 is an open-source project written primarily in Python, with 61k stars on GitHub. It was last updated in July 2026.\n\n```\nnpm install -g @mem0/cli      # or: pip install mem0-cli\n```\n\n## mem0 vs. the alternatives\n\n[All 22 alternatives →](/alternatives/mem0)", "url": "https://wpnews.pro/news/mem0-shipped-an-update", "canonical_source": "https://agentsearchengine.app/agents/mem0", "published_at": "2026-07-21 12:44:35+00:00", "updated_at": "2026-07-21 13:36:30.274041+00:00", "lang": "en", "topics": ["ai-agents", "ai-tools", "ai-infrastructure", "developer-tools"], "entities": ["mem0", "GitHub"], "alternates": {"html": "https://wpnews.pro/news/mem0-shipped-an-update", "markdown": "https://wpnews.pro/news/mem0-shipped-an-update.md", "text": "https://wpnews.pro/news/mem0-shipped-an-update.txt", "jsonld": "https://wpnews.pro/news/mem0-shipped-an-update.jsonld"}}
