The MemPalace local AI structured memory system launched by the open source community aims to solve the problems of easy forgetting of large model sessions, high cost and slow response of long context APIs. This method draws on the logic of the ancient Greek "memory palace" to build a four-layer memory stack architecture and adhere to high-granularity word-for-word original storage. Experimental data shows that the system achieves a retrieval accuracy of 96.6%, requires only 170 Tokens to start, and has a text compression ratio of 30 times. This not only allows AI to achieve permanent memory across sessions at zero API cost, but also allows local AI assistants to be more economical, more accurate, and better aware of user preferences while ensuring factual restoration, effectively expanding the application boundaries of personal AI knowledge bases.
