UnverifiedIn engineering implementation, the persistent memory layer typically exists independently of the large language model itself, as an external service or database75% similarUnverifiedConversational memory is stored in the form of memory summaries, which can become skewed as conversations grow, whereas global personalization instructions are hard-coded into the system prompt of every request and are not affected by memory degradation.74% similarUnverifiedCross-session memory systems are typically divided into several layers: short-term context memory, long-term explicit memory, and implicit preference memory.73% similarVerifiedThe memory of large language models fundamentally relies on the attention mechanism of the Transformer architecture, and its effective information capacity is limited by the number of tokens in the context window.71% similarUnverified实际开发中通常在存储长期记忆前让大模型对对话做总结摘要，提炼核心信息后再持久化，以节省空间并提高检索精确度71% similar
