The Four Types of Memory

Unlike standard apps, Agents need memory modeled somewhat like a human brain:

  1. Working Memory: The current LLM context window. Temporary, fast, but limited by token limits.
  2. Episodic Memory: Logs of past actions taken during this specific session.
  3. Semantic Memory: Facts, entity profiles, and user preferences stored in a vector DB.
  4. Procedural Memory: "How-to" knowledge (system prompts, tool definitions).
