Someone just open-sourced the highest-scoring AI memory system ever benchmarked.
Someone just open-sourced the highest-scoring AI memory system ever benchmarked.
96.6% on LongMemEval. Nothing else is close.
It's called MemPalace. And it gives your AI a memory that actually works.
Not a summarizer. Not a vector database that forgets the details. Not a sliding context window that drops everything from last week.
A structured memory palace. With wings. With rooms. With a knowledge graph connecting everything together.
Your AI remembers everything you told it. Forever. Locally. No API calls.
Here is how it works:
-> Every conversation is stored verbatim. Word for word. Nothing compressed away.
-> Memory is organized into a palace structure. Wings group topics. Rooms hold specific knowledge.
-> A knowledge graph maps connections between everything stored.
-> Fully local. Your data never leaves your machine.
-> Persistent across sessions. Close the app. Reopen it tomorrow. It remembers.
The benchmark that matters:
LongMemEval is the hardest long-term memory benchmark in AI research. It tests whether a system can retrieve specific details from thousands of past interactions accurately.
MemPalace scored 96.6%.
For context, most commercial AI memory systems score in the 60 to 75% range.
This is not a marginal improvement. It is a different category.
50.8K GitHub stars. 4.5K gained today alone.
No subscriptions. No cloud. No API keys. Just memory that works.
100% Open Source. Python. Free forever.
