Holistic Evaluation of Memory Substrates for LLM Agents
August 14, 2026
This study evaluates various memory substrates, including dense/sparse indices, structural stores, and parametric updates, across three backbone models. The results demonstrate that no single memory architecture is universally optimal for all agentic operating regimes.
HOW THIS AFFECTS YOU
