Actress Milla Jovovich has co-created Mem-Palace, a free, open-source AI memory system that hit roughly 7,000 Github stars within days of its April 2026 release.
Key Takeaways:
Milla Jovovich co-created Mem-Palace, an open-source artificial intelligence (AI) memory tool that reached ~7,000 Github stars by April 7, 2026. Mem-Palace scored 96.6% on LongMemEval R@5, outperforming paid rivals Mem0 and Zep at roughly 85%. Ben Sigman engineered the v3.0.0 release, with MCP integration supporting 19 tools for Claude, ChatGPT, and other LLMs. Milla Jovovich Designs AI Memory Architecture Inspired by Ancient Greek Memory TechniquesThe system organizes memory using a structure borrowed from ancient Greek orators, who memorized long speeches by placing information inside imagined physical spaces. Mem-Palace applies that same logic digitally, sorting data into Wings, Rooms, Halls, and Drawers.
Performance benchmarks from version 3.0.0, released around April 6, 2026, place Mem-Palace at 96.6 percent on LongMemEval R@5 without an API call, and at 100 percent when using a lightweight Haiku rerank. Paid competitors Mem0 and Zep score around 85 percent on the same benchmark.
“The claimed 100% LongMemEval score uses targeted fixes for the 3 failing questions and LLM reranking (held-out score: 98.4%). The 100% LoCoMo score uses top-k=50 exceeding session count with reranking (honest top-10 no rerank: 88.9%).”
The system’s palace structure alone improves retrieval by 34 percent over flat storage. A four-layer memory stack loads only relevant context on startup, keeping token usage to roughly 170 tokens for wake-up.
Mem-Palace also includes AAAK Compression, a lossless dialect that compresses data at 30 times the original size while remaining readable by any text-based LLM. A Temporal Knowledge Graph built on SQLite and ChromaDB tracks entity relationships with validity windows, meaning facts can expire or be invalidated over time.
For developers building AI agents, Jovovich’s Mem-Palace tool ships with Model Context Protocol integration across 19 tools, including auto-save functionality inside Claude Code.
The project is MIT-licensed and available via pip install mem-palace. Jovovich is listed as the repository owner under the Github username milla-jovovich.
Separately, in December 2025, Jovovich participated in a viral Instagram reel series by director Sergio Cilli titled “Will AI Replace Us?!” The videos showed her auditioning head-to-head against an AI-generated actor for a role in an action thriller, drawing tens of thousands of views across platforms.
Mem-Palace remains under active development as of April 7, 2026, with recent updates adding narrative palace walkthroughs and expanded benchmark documentation.
