MongoDB Guide Defines Memory Engineering for AI Agents
TheTuringPost · x · 2026-08-23
MongoDB released a practical guide on AI Agent memory, proposing "Memory Engineering" as a new discipline. It defines Agent Memory as the persistent system enabling agents to accumulate knowledge, maintain context, and adapt behavior.
Core Concepts:
- Memory goes beyond RAG or chat history.
- Memory units should include context, strength, and relationships, decaying over time instead of deletion.
Memory Types:
- Short-term: Working Memory, Semantic Cache.
- Long-term: Episodic, Semantic, Procedural, and Associative Memory, plus Shared Memory.
Application Modes:
- Assistant Mode (conversational)
- Workflow Mode (multi-step processes)
- Deep Research Mode (comprehensive analysis)
