The Personal Small Model (PSM): Memory as a Learned Cognitive Primitive

The Problem With Every Memory System Today mem0, Zep, Letta, MemPalace - they all make the same foundational assumption: Memory is a storage problem. Build a good enough database. Implement a smart enough retrieval mechanism. Inject the results into the LLM’s context. The model consumes the fragments. The model forgets. The cycle repeats. This post argues that assumption is architecturally wrong, and proposes an alternative. The Insight: Memory Is a Cognitive Skill, Not a Database The human brain didn’t solve long-term memory by building a perfect database.
