LLM agent memory is evolving to include persistent storage, retrieval, updating, consolidation, and lifecycle governance. Assessing these systems requires looking beyond the final task result.
The analysis notes that existing evaluations often use end-to-end metrics and treat memory as a black box. This can obscure which memory capabilities a benchmark actually measures.
When studying a benchmark, identify which stages of the memory lifecycle it evaluates and which it leaves out. Where possible, distinguish final-task performance from the quality of storage, retrieval, updating, and consolidation.
