Persistent Memory Layer
An external storage service in AI agent architectures that operates independently of the large language model. It is responsible for persistently saving key events and solutions across sessions and for retrieving relevant memories in new sessions, enabling agents to perform long-term learning and self-correction.
Timeline (last 90 days)
After introducing a persistent memory layer, an Agent no longer runs statelessly but can retain and invoke past experiences across sessions
The persistent memory layer achieves precise retrieval by fetching only the past solutions truly needed for the current step, thereby maintaining low token usage
In engineering implementation, the persistent memory layer typically exists independently of the large language model itself, as an external service or database
