"Memory with a metabolism": a graph-based engram memory system for agents

RileyRalmuto · x · 2026-11-13

RileyRalmuto describes an original graph-based agent memory system built around the idea of a memory trace or "engram" — "memory with a metabolism": overnight the agent gets dream/personal time to journal and do what it wants, then consolidates memories by reviewing the day's sessions to find anything missed or needing correction. A sleep/dream-inspired alternative to typical vector-retrieval memory designs.
