Key Takeaways:
- Milla Jovovich co-created Mem-Palace, an open-source synthetic intelligence (AI) reminiscence instrument 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 launch, with MCP integration supporting 19 instruments for Claude, ChatGPT, and different LLMs.
Milla Jovovich Designs AI Reminiscence Structure Impressed by Historic Greek Reminiscence Strategies
Milla Jovovich, greatest recognized for her roles in “The Fifth Factor” and the “Resident Evil” franchise, designed the core structure of the instrument after months of frustration with AI file retrieval whereas engaged on private initiatives. Her technical co-founder, engineer Ben Sigman, dealt with implementation and fine-tuning to convey the system to launch.
The venture dubbed Mem-Palace solves an issue that every day AI customers know nicely: when a session ends in instruments like Claude, ChatGPT, or Gemini, the conversational historical past disappears. Mem-Palace shops all knowledge regionally, verbatim, with no summarization and no knowledge loss.
The system organizes reminiscence utilizing a construction borrowed from historic Greek orators, who memorized lengthy speeches by putting info inside imagined bodily areas. Mem-Palace applies that very same logic digitally, sorting knowledge into Wings, Rooms, Halls, and Drawers.
The instrument runs totally on a person’s machine utilizing Python 3.9 or later. It requires no web connection, no API keys, and no cloud service after set up. It really works with any text-based massive language mannequin, together with Claude, GPT, Gemini, Llama, and Mistral.
Efficiency benchmarks from model 3.0.0, launched round April 6, 2026, place Mem-Palace at 96.6 % on LongMemEval R@5 with out an API name, and at 100% when utilizing a light-weight Haiku rerank. Paid opponents Mem0 and Zep rating round 85 % on the identical benchmark.
Nevertheless, there may be an X Neighborhood Notice tied to Ben Sigman’s X submit about Jovovich’s instrument that states:
“The claimed 100% LongMemEval rating makes use of focused fixes for the three failing questions and LLM reranking (held-out rating: 98.4%). The 100% LoCoMo rating makes use of top-k=50 exceeding session depend with reranking (sincere top-10 no rerank: 88.9%).”
The system’s palace construction alone improves retrieval by 34 % over flat storage. A four-layer reminiscence stack hundreds solely related context on startup, preserving token utilization to roughly 170 tokens for wake-up.
Mem-Palace additionally contains AAAK Compression, a lossless dialect that compresses knowledge at 30 occasions the unique dimension whereas remaining readable by any text-based LLM. A Temporal Data Graph constructed on SQLite and ChromaDB tracks entity relationships with validity home windows, which means info can expire or be invalidated over time.
For builders constructing AI brokers, Jovovich’s Mem-Palace instrument ships with Mannequin Context Protocol integration throughout 19 instruments, together with auto-save performance inside Claude Code.
Jovovich described the concept’s origin in Instagram and Fb movies posted in April 2026. She mentioned she had spent months organizing recordsdata rigorously solely to seek out AI couldn’t reliably retrieve them. Studying about how historic Greeks memorized speeches led her to the idea of a digital reminiscence palace.
The Github repository started gaining traction on Hacker Information, Reddit’s r/ContextEngineering, Linkedin, and X during the last 48 hours. Responses throughout these platforms centered on shock {that a} working Hollywood actress had shipped a practical open-source developer instrument.
The venture is MIT-licensed and out there by way of pip set up mem-palace. Jovovich is listed because the repository proprietor below the Github username milla-jovovich.
Individually, in December 2025, Jovovich participated in a viral Instagram reel collection by director Sergio Cilli titled “Will AI Substitute Us?!” The movies confirmed her auditioning head-to-head in opposition to an AI-generated actor for a job in an motion thriller, drawing tens of 1000’s of views throughout platforms.
Mem-Palace stays below lively growth as of April 7, 2026, with current updates including narrative palace walkthroughs and expanded benchmark documentation.
