Milla Jovovich, the female lead of "Resident Evil," has open-sourced an AI memory system called MemPalace, which achieved the first-ever perfect score in industry benchmark tests. The famous Hollywood actor, widely known for her role as Alice in the "Resident Evil" series, recently open-sourced a project called MemPalace on GitHub. This project scored 100% (the first perfect score) on the industry standard benchmark test LongMemEval and performed well on other tests such as ConvoMem and LoCoMo, surpassing many paid AI memory products.
Milla discovered that after using AI for several months, a large amount of decision-making and thinking results were lost due to existing memory systems. These systems often let AI decide what is worth remembering, which was not what she wanted. She hoped that AI could retain and retrieve memories more organically, so she and her friend Ben Sigman spent months developing MemPalace using Claude Code.
The system draws inspiration from the ancient Greek method of loci, organizing memories into navigable spatial structures with levels such as "wings, halls, and rooms," forming an intuitive architecture similar to human memory. It also uses AAAK lossless compression technology, which can compress 1000 English tokens to about 120, allowing LLMs to read directly without a decoder, achieving about 30 times compression efficiency. In addition, it includes features such as contradiction detection and time-effective knowledge graphs, supporting semantic search, enabling AI to quickly load user context (such as family, projects, preferences) before dialogue.
MemPalace runs entirely locally, based on SQLite and ChromaDB, requiring no API key, no cloud dependency, and no subscription fee, with data remaining entirely on the user's device. The project is released under the MIT open-source license and has been launched on GitHub (repository: milla-jovovich/mempalace), quickly attracting community attention. A Hollywood action star has developed a memory product that surpasses many professional AI companies, which undoubtedly demonstrates the limitless imagination and open innovation spirit of the current AI era. Interested users can directly access the GitHub repository to download and experience it for free.
