AI Agents Need Four Types of Memory to Mimic Human Capabilities
_jaydeepkarale · x · 2026-08-25
The author argues that AI agents should mirror the human memory system by incorporating four distinct types of memory for different tasks:
- Working Memory: What you are thinking about right now.
→ For agents: current conversation, context, and tool results.
- Semantic Memory: What you know.
→ Facts, concepts, documentation, and knowledge bases.
- Procedural Memory: What you know how to do.
→ Skills, workflows, tool-use patterns, and instructions.
- Episodic Memory: What you remember experiencing.
→ Past conversations, successes, failures, and important events.
A simple way to remember:
- Working → What am I doing?
- Semantic → What do I know?
- Procedural → How do I do it?
- Episodic → What happened before?
