Is Complex Agentic Memory Always Needed? Naive RAG Is Stronger Than We Thought

One-line takeaway

A naive RAG baseline (dense retrieval plus reranking over raw history) ranks first in six of seven settings across LoCoMo, LongMemEval, MEME and MemoryAgentBench, beating the strongest agentic memory system by 0.13–5.53 points thanks to higher evidence coverage.

论文发现朴素 RAG（对原始对话历史做稠密检索加重排）在 LoCoMo、LongMemEval 等长期记忆评测的 7 个设置里 6 个排第一，比最强的复杂智能体记忆系统高 0.13–5.53 分，原因是它对必要证据的覆盖更高。
