On April 6, Resident Evil and The Fifth Element star Milla Jovovich announced that she was teaming up with crypto bro Ben Sigman, owner and CEO of “Bitcoin lending” marketplace Libre, to create MemPalace, an open-source “AI memory system.” According to Sigman, MemPalace has earned “a perfect score on the standard benchmark – beating every product in the space, free or paid.”
The most surprising thing about MemPalace’s announcement is that, according to both its GitHub page and a post on Jovovich’s official Instagram, Milla Jovovich herself is one of its primary architects and coders. Jovovich stated that she decided to start work on MemPalace after running into some issues with AI coding during a “big gaming project” she’s been working on, which prompted her to team up with Sigman.
Many aren’t buying Sigman’s and Jovovich’s friendship, however, as they believe that Sigman is simply using the Resident Evil actresses’ fame to promote his latest AI-slop project. “A crypto bro and an actress decided to do AI. It was shredded within minutes,” writes one user on X. “Do it properly. Study math. Teach your kids math.”
Sigman has made some pretty huge claims about MemPalace, like for instance that it scored a “100% recall on LongMemEval,” which is supposedly the “first perfect score ever recorded.” For context, LongMemEval is a benchmark devised to test the “long-term memory abilities of chat assistants,” such as ChatGPT and Claude. LLMs have selective memories, so those who use them often have to remind AI of conversations they’ve previously had. According to Sigman’s claim, MemPalace suffers from no such forgetfulness.
The problem is that, according to those who tested the code in MemPalace’s GitHub repository, Sigman’s claims are complete rubbish. “Tested the currently viral MemPalace on MABench (Long Memory Eval),” writes user parcadei on X. “When you plug it in and have an LLM answer questions, you get the right answer 17% of the time.” “Real score, but measured in ‘raw mode’ — uncompressed verbatim text stored in ChromaDB, standard nearest-neighbor retrieval,” writes lhl on GitHub. “The palace structure (wings/rooms/halls) is not involved. This measures ChromaDB’s default embedding model performance, not MemPalace.”
2/ LongMemEval_s has ~50 sessions per question.
MemPalace retrieves at session granularity with n_results=50 (all of them). So R@5 asks: “is the right session in your top 5 out of ~50?”

The other issue is that many have called Jovovich’s involvement in the coding process into question, as a now-deleted user was initially credited with much of the work, and their name can still be found in MemPalace’s GitHub files. “No git author history, no account connected to whoever wrote the code of this codebase. It doesn’t add up,” writes Aimar Haddadi on X. “The account who pushed the original repo, named: aya-thekeeper, under aya-thekeeper/mempal got deleted right after the repo got published.”
To Sigman’s credit, the claim that he and Jovovich are “good friends” does have some basis—by which I mean that she promoted his cryptocurrency book for him back in October of 2025.
So, with all of this in mind, what would the grift be here? If Jovovich’s involvement in the project is purely promotional and MemPalace isn’t as “perfect” as Sigman has claimed, it’s hard to see how they’d get any money out of all this, considering that MemPalace itself is purely open-source.
Well, it is a little bit suspicious that a cryptocoin called MemPalace, for which Jovovich and Sigman have a 50-percent creator reward split, was pumped and subsequently dumped within 24 hours of MemPalace’s announcement. That being said, as with all things crypto, it’s not possible to prove that they’re actually directly involved with the MemPalace coin; still, Sigman’s shady crypto bro marketplace and Jovovich’s promotion of said marketplace via Sigman’s book certainly aren’t doing either of them any favors.
Kotaku has reached out to both Jovovich and Sigman to verify the extent of their involvement in MemPalace, and to find out if they’re in any way associated with the MemPalace crypto coin.
