A memory operating system for large language models and AI agents that unifies long-term, working, and external memory management, enabling context-aware and personalized interactions with multi-modal storage capabilities.
One-Minute Overview#
MemOS is a memory operating system designed for AI systems, providing a unified memory management solution for LLMs and AI agents. It integrates long-term, working, and external memory, supporting storage and retrieval of multiple modalities including text, images, tool traces, and personas, enabling AI systems to maintain context awareness and provide personalized interactions. Developers can easily integrate and manage AI "memory" capabilities through simple APIs.
Core Value: Structuring and visualizing AI "memory" with full management capabilities, solving the problems of long-term memory and context continuity in AI systems.
Quickstart#
Installation Difficulty: Medium - Requires configuring multiple dependent services (like Neo4j and Qdrant)
# Clone repository and install dependencies
git clone https://github.com/MemTensor/MemOS.git
cd MemOS
pip install -r ./docker/requirements.txt
Is this suitable for my scenario?
- ✅ AI applications requiring long-term memory: Such as personalized assistants, intelligent customer service, knowledge management assistants
- ✅ Multi-modal AI systems: Applications that need to process various types of information like text and images
- ✅ Enterprise AI deployment: Team projects requiring data isolation and sharing
- ❌ Simple single-conversation applications: Simple Q&A scenarios without complex memory needs
Core Capabilities#
1. Unified Memory API - Simplified Memory Management#
A single API to add, retrieve, edit, and delete memory—structured as a graph, inspectable and editable by design, not a black-box embedding store. Actual Value: Developers don't need to handle complex underlying storage implementations, focusing on AI application logic while retaining full control over the memory system.
2. Multi-Modal Memory Support -全媒体信息处理#
Natively supports text, images, tool traces, and personas, retrieved and reasoned together in one memory system. Actual Value: AI systems can understand and process multiple types of information simultaneously, such as image references in conversations, past tool usage habits, etc., enabling more natural interactions.
3. Multi-Cube Knowledge Base Management - Flexible Knowledge Organization#
Manage multiple knowledge bases as composable memory cubes, enabling isolation, controlled sharing, and dynamic composition across users, projects, and agents. Actual Value: Enterprises can isolate data by project or user while supporting cross-project knowledge sharing, protecting privacy while promoting collaboration.
4. Asynchronous Memory Ingestion - High Performance Stable Operation#
Run memory operations asynchronously with millisecond-level latency for production stability under high concurrency. Actual Value: Maintains system response speed and stability in high-concurrency scenarios without blocking the entire AI system due to memory operations.
5. Memory Feedback & Correction - Continuous Memory Optimization#
Refine memory with natural-language feedback—correcting, supplementing, or replacing existing memories over time. Actual Value: AI systems can continuously learn and improve memory accuracy based on user feedback, reducing "AI hallucination" problems.
