UnverifiedEven if a model supports a context window of 128K or longer, stuffing all historical information into the prompt does not guarantee the model will correctly utilize that information, as attention dilution can cause critical information to be overlooked.79% similarUnverifiedLarge models lack true long-term memory; every conversation starts from scratch, and they can only compensate by relying on external databases such as RAG (Retrieval-Augmented Generation).72% similarUnverified现有向量数据库记忆方案缺乏时效性衰减机制,无法区分记忆是否被采纳并产生正向效果,也没有机制合并冗余或删除有害记忆72% similarUnverifiedEven models with a 128K or larger context window cannot automatically perceive project directory structure, existing database schemas, team coding standards, or historical decisions.71% similarUnverified当记忆量级达到万级以上、尤其是非结构化长文本记忆时,暴力搜索延迟线性增长至无法接受,此时应引入向量数据库的语义索引71% similar
