Episodic Memory
Stored records of specific past interactions — what happened in previous conversations or task runs — that an agent can retrieve and reference. Without episodic memory, an agent has no recall of "last Tuesday you told me to always format reports as PDFs." With it, agents can adapt their behavior based on what they've learned about you or your team over time. Technically, this is external storage that the agent reads, not a feature built into the model.
In practice
You're building a personal assistant that should remember what you worked on last Tuesday. Episodic memory stores specific past events — "last Tuesday you drafted a proposal for Acme Corp" — so the assistant can reference them later. It's different from general knowledge; it's memory of specific things that happened in your interactions.
