When Does Memory Help? A Cost-Aware Evaluation of Long-Term Memory in Tool-Using LLM Agents
MERIT tests whether long-term memory changes what tool-using agents do—and whether the gains justify the cost.
Why it matters: For teams building tool-using agents, the result is that adding memory is not enough: the implementation can move task success by up to 60 points, and evaluation should account for both task outcomes and memory-operation costs.
