Milla Jovovich is an actress, model, and AI developer. In 2026, she co-created MemPalace, an open-source AI memory system that achieved the first perfect score on the LongMemEval benchmark. The project earned 19,500+ GitHub stars and sparked global discussion about celebrity involvement in open-source software. Jovovich built the system using Claude Code alongside developer Ben Sigman, establishing herself as one of the most unexpected figures in the AI development community.
The Tech Story: How Milla Jovovich Learned to Code
Milla Jovovich's path into programming started with a problem, not a passion project. In early 2026, she was using AI assistants — ChatGPT, Claude, Gemini — for everything from business decisions to creative brainstorming. She poured thousands of conversations into these systems. Then she'd open a new session and all of it was gone.
Every existing solution she tried — Mem0, Zep, and others — used AI to decide what was worth keeping. They'd summarize, extract “key facts,” and discard the rest. The nuance, the reasoning, the context that made those conversations valuable? Gone.
Jovovich had a different idea: store everything verbatim. Don't let AI rewrite your memories before filing them away. She partnered with developer Ben Sigman in February 2026, and they spent months building MemPalace using Claude Code, Anthropic's AI-assisted coding environment.
The result launched on April 5, 2026. Within 48 hours, MemPalace had 7,000+ GitHub stars. Within a week, it had crossed 19,000 — making Milla Jovovich's GitHub profile one of the most-starred in the AI category.
Milla Jovovich's GitHub: What She's Actually Shipped
Milla Jovovich's GitHub is github.com/milla-jovovich. It's the answer a lot of people type into Google when they first hear the story — and yes, it's a real profile with real commits. The headline repository is milla-jovovich/mempalace, an open-source AI memory framework that crossed 19,000 stars within its first week.
The repository structure is unusual for a celebrity-associated project in that it is genuinely production-grade:
- Language: Python 3.9+ with optional Rust extensions for vector search acceleration.
- Storage layer: ChromaDB for vector embeddings, SQLite for metadata and timestamps.
- Retrieval: BM25 lexical search combined with semantic vector retrieval — a 4-layer stack labeled L0 through L3.
- Compression: AAAK, a custom lossless dialect that achieves ~30x compression ratios on stored conversation history.
- Integrations: 19 MCP tools exposing the memory engine to Claude Code, plus adapters for ChatGPT, Cursor, and local LLMs like Llama and Mistral.
- License: MIT, with no optional paid tier — a deliberate choice Jovovich has publicly defended in comment threads.
The commit history is where skepticism usually ends. Early commits land in bursts that match Jovovich's public schedule — long gaps around press days and film shoots, dense batches on weekends. Ben Sigman's commits are interleaved throughout, which is consistent with the “vibe coding” workflow she describes: she drafts direction and reviews outputs while Sigman handles the harder systems-level work.

MemPalace: What Milla Jovovich Built
MemPalace is an open-source AI memory system designed around one principle: never throw anything away. While competing systems like Mem0 compress and summarize, MemPalace stores every conversation verbatim and uses a multi-layered retrieval engine to surface relevant context on demand.

The Internet's Reaction to Milla Jovovich Coding
When Milla Jovovich's GitHub repository started climbing the trending charts, the developer community had strong opinions. Some praised the architecture. Others questioned whether a celebrity could genuinely build software. The discussion spanned Hacker News, Reddit, and X (Twitter).
“Milla Jovovich having a GitHub with more stars than most YC companies is the most 2026 thing I've ever seen.”
— Hacker News commenter
“I cloned the repo expecting a joke. The architecture is genuinely well-designed. Verbatim storage with smart retrieval is the correct approach.”
— Senior ML engineer, Reddit r/LocalLLaMA
“A Resident Evil actress just shipped a better product than a $24M startup. We live in interesting times.”
— Developer on X (Twitter)
The benchmark controversy added fuel. Researchers questioned whether the 100% LongMemEval score was achieved through benchmark engineering. The MemPalace team responded by publishing full evaluation code and acknowledging that the raw zero-API score is 96.6%.

Frequently Asked Questions About Milla Jovovich
Does Milla Jovovich actually code?
Yes. Milla Jovovich co-developed MemPalace using Claude Code, Anthropic's AI-assisted coding environment. She describes her approach as 'vibe coding' — she directs the architecture, writes prompts, reviews outputs, and iterates on the system design while Claude Code handles much of the syntax. The result is a production-grade AI memory system with 19,500+ GitHub stars.
What is Milla Jovovich's GitHub?
Milla Jovovich's GitHub is github.com/milla-jovovich. Her primary repository is MemPalace, the open-source AI memory system that scored 100% on the LongMemEval benchmark. The project is MIT licensed and has earned over 19,000 stars since launching in April 2026.
Why did Milla Jovovich build an AI tool?
Jovovich became frustrated with AI amnesia — the fact that AI assistants like ChatGPT and Claude forget everything between sessions. After trying existing memory tools like Mem0 and Zep, she found they all used AI to decide what to remember, discarding nuance and context. She partnered with developer Ben Sigman to build a system that stores everything verbatim.
Is Milla Jovovich a software engineer?
Milla Jovovich describes herself as a 'vibe coder' rather than a traditional software engineer. She uses AI-assisted development tools — primarily Claude Code — to build software. Her background is in acting and modeling, but she has demonstrated the ability to ship production-grade open-source software that outperforms venture-backed alternatives on standard benchmarks.
What is MemPalace?
MemPalace is a free, open-source AI memory system co-created by Milla Jovovich and Ben Sigman. It is the highest-scoring system on the LongMemEval benchmark with a 100% score (96.6% raw, zero-API). Unlike alternatives that summarize and discard data, MemPalace stores all conversations verbatim. It is MIT licensed and costs $0 to run.
Who is Ben Sigman?
Ben Sigman is the developer who partnered with Milla Jovovich to build MemPalace. He brought the engineering expertise while Jovovich provided the product vision and user perspective. Together they built the system using Claude Code over several months in early 2026.
What is Milla Jovovich's GitHub username?
Milla Jovovich's GitHub username is @milla-jovovich. Her profile is at github.com/milla-jovovich. The primary repository she is known for is milla-jovovich/mempalace, which is MIT-licensed and has earned over 19,500 stars since launching in April 2026.
How many GitHub stars does Milla Jovovich have?
Milla Jovovich's main repository, MemPalace, has earned 19,500+ GitHub stars since launching on April 5, 2026. It hit 7,000 stars within the first 48 hours, making it one of the fastest-growing open-source AI projects in history. Combined across her public repositories, her GitHub profile is among the most-starred in the AI memory category.
What programming language does Milla Jovovich use?
Milla Jovovich's primary repository, MemPalace, is written in Python. The stack also includes SQLite for metadata storage and ChromaDB for vector search. She describes her development workflow as 'vibe coding' — she directs the architecture and reviews outputs while Claude Code (an AI coding assistant) handles most of the syntax generation.
Is Milla Jovovich's GitHub account real?
Yes. Milla Jovovich's GitHub account at github.com/milla-jovovich is real and has been confirmed by her co-developer Ben Sigman in multiple public posts. The account's activity (including commits, issues, and pull requests on the mempalace repository) is verifiable on GitHub directly. Initial skepticism from the developer community has largely faded as her contributions have been independently reviewed.
What is vibe coding?
'Vibe coding' is the term Milla Jovovich uses to describe her development approach. Instead of writing code character-by-character, she directs an AI coding agent (Claude Code) at a higher level: defining what she wants, reviewing the generated code, testing it, and iterating on the design. The term has since spread through the developer community as shorthand for AI-assisted, intent-driven development.
