Memory system
Infrastructure that saves and reloads information so an agent can retain useful state across sessions.
Illustrative conversation
- Why did the agent forget the preference I gave it yesterday?
- Check whether it was saved, retrieved, and still current. Even correctly loaded memory can be used incorrectly; the answer alone cannot locate the failure.
Definition
A memory system persists selected information from one agent run and makes it available to later runs. It may store full conversation items, compact summaries, user preferences, or learned project facts, with different retention and retrieval rules. Memory is not the model's context window: stored material has to be retrieved and inserted into a future run, and applications must manage staleness, privacy, isolation, and deletion deliberately.
