new paper: RLVR Exploration-Exploitation🫨

we carefully studied several interesting open questions regarding RLVR dynamics in entropy and clipping mechanism...

p.s. "uncontaminated" Llama could also improve under random reward, while Qwen-Math might also fail to improve.

Introducing The Most Advanced Memory System for LLM Agents

MIRIX is by far the most advanced memory system in the world, designed to make AI truly remember, learn, and help you over time.

Website: https://t.co/XchkbhnAGZ
Paper: https://t.co/eQrJQwux7C
Github: https://t.co/axrseZp5ft

1️⃣ Performance Benchmarks
On ScreenshotVQA: 410% improvements over Gemini with 93.3% storage reduction; 35% improvements over RAG with 99.9% storage reduction!
On LOCOMO, we obtained 85.4% accuracy, the current state-of-the-art performance (better than Mem0, MemOS, Zep, ...)

2️⃣ Six Core Memory Types (Inspired by Human Cognition)
1. Core Memory: Stores the AI’s personality and your long-term preferences: tone, settings, identity.
2. Episodic Memory: Your personal “event log.”
3. Semantic Memory: Facts, concepts, and your social graph.
4. Procedural Memory: How-tos and workflows.
5. Resource Memory: Your raw materials, files, notes.
6. Knowledge Vault: Verbatim information, your addresses (less sensitive), ID numbers (highly sensitive), encrypted with multi-level access controls.

3️⃣ Multi-Agent Workflow
We have eight different agents:
⚙️ Meta Memory Manager: Analyzes inputs, then routes them to the right memory modules.
⚙️ Memory Managers: Specialized for each memory type, insert, deduplicate, merge, index, embed data.
⚙️ Chat Agent: Interfaces with the user, synthesizes context-aware responses

Then during memory update:
(1) Checks if similar data already exists;
(2) Let meta memory manager analyze and route to different agents,
(3) After that, Each module structures, merges, and stores in parallel.
(4) Finally, all modules report back when done.

💡 This is why we call it an AI “cognitive prototype.” It’s not just an index. It’s the first step toward a system that remembers, reasons, and grows with you.

A Personal AI Assistant that Sees What You See and Understands You - Powered by Our Most Advanced Memory System

🧠 Imagine having a personal AI that truly remembers you.

Not just another chatbot. Not just a search box.

A real assistant that sees what you see, understands what you care about, and helps you turn scattered information into clarity and action.

Today, we’re introducing MIRIX, the first AI personal assistant powered by the world’s most advanced memory system.

📈 Why does this matter?

We live in an era of overwhelming information.

Most AI tools can only answer questions in the moment. But real productivity—and real understanding—comes from memory.

That’s why we built a system that doesn’t just process your input but continuously learns, organizes, and evolves alongside you.

💡 What can you do with it?

Instantly recall anything you’ve seen or worked on;
Draft and polish applications, reports, or emails;
Analyze documents and get concise summaries;
Keep your knowledge organized automatically;
Never lose important insights again...

🔒 Your data stays yours.

Everything you share is stored securely and privately. You control what to record and what to delete—always.

🚀 We believe this is the future of AI:

A true second brain that doesn’t just respond, but remembers and understands.
