메모리는 정해진 언어 에이전트가 과거의 경험에서 유용한 차별을 미래의 결정을 통해 유용한 차별을 전달할 수 있도록 해줍니다. 그 틀은 어떤 차별이 생존하는지, 한계된 에이전트가 그들을 사용할 수 있는지, 그리고 요구 사항이 진화함에 따라 복구 또는 수정될 수 있는지에 따라 무엇을 가져올 수 있는지에 따라 달라집니다. 우리는 지속적인 상태, 운영용 사용 및 비용 회복 및 검토를 통해 원래의 상태에서이 값을 따르는 결정 이론 프레임 워크를 개발합니다. 원래와 보존된 값은 방지된 작업 손실의 단위로 표현되며; 위험 비용 경계는 사용 간에 달성 가능한 복구 및 보존을 설명합니다. 알 수 없는 수요는

Memory enables language agents to carry useful distinctions from past experience into future decisions. Its value depends on which distinctions survive, whether a bounded agent can use them, and what can be recovered or revised as demands evolve. We develop a decision-theoretic framework that follows this value from raw history through persistent state, operational use, and costly recovery and revision. Original and retained value are expressed in units of avoided task loss; risk-cost frontiers describe attainable recovery and preservation across uses. Unknown demand yields value profiles, while interactive feedback changes the distribution of future work. A cost-aware simulation condition and five minimal counterexamples expose the roles of information timing, retrieval access, component interaction, feedback and demand uncertainty. In particular, a pointer with zero mutual information about the answer can still reduce the cost of exact recovery. Diagnostics on LoCoMo, a two-project update task and longitudinal cases exhibit failures of preservation, use and measurement. At fixed retrieved evidence, a saved ledger changes subsequent answers; at fixed agent outputs, an evaluator revision changes scores. The framework connects these distinctions to operational risk bounds and testable principles for allocating memory, preserving recovery options and revising evidence dependencies.
