MemOS - An open-source AI memory management platform supporting multiple memory types

What is MemOS

MemOS is an open-source AI memory management operating system that provides long-term memory capabilities for agents and AI applications. Through a unified memory abstraction layer, MemOS supports multiple memory types (such as text memory, activation memory, and parameter memory), and features dynamic knowledge graphs, memory scheduling, and lifecycle management. MemOS enables AI systems to remember users' past information like humans do, actively recall memories in subsequent interactions, and achieve a more coherent and personalized conversation experience. MemOS's powerful memory scheduling and storage capabilities address the limitations of traditional RAG, making it suitable for various scenarios such as personalized assistants and team knowledge bases.

MemOS's main features

• Long-term memory storage: MemOS provides multiple types such as text memory, activation memory, and parameter memory, combined with dynamic knowledge graphs to achieve structured memory, supporting long-term information storage and deep associations.
• Memory scheduling and management: Through predictive scheduling, comprehensive scheduling, and asynchronous advanced retrieval, MemOS enables fast, context-aware memory access and improves response efficiency.
• Memory lifecycle management: MemOS provides a unified interface that supports saving, updating, migrating, and rolling back memories, ensuring the continuity and consistency of memory.
• Personalization and coherence: MemOS can remember information such as user habits and preferences, enabling personalized conversations, and maintains memory across sessions and applications to ensure interaction coherence.
• Open extensibility: MemOS provides flexible API interfaces and supports integration with existing frameworks. Developers can customize memory modules and data sources to meet diverse needs.
• Multi-scenario support: The tool is suitable for various scenarios such as personalized assistants, team knowledge bases, and family life assistants, and can be extended to functions such as AI calendars and intelligent writing assistants.
• Performance optimization: Through multi-layer memory scheduling and asynchronous retrieval mechanisms, MemOS significantly improves the performance and accuracy of memory recall and reduces hallucinations.

How to use MemOS

• Use the cloud platform API: Visit the MemOS official website https://memos.openmem.net/ , register an account to obtain an API key, and by calling the official API interfaces, quickly add memory functionality to applications without local deployment.
• Local deployment: From the MemOS GitHub repository https://github.com/MemTensor/MemOS克隆代码，安装依赖配置环境，启动本地服务后能在本地环境中使用 all MemOS features, suitable for scenarios requiring a high degree of customization.
• Use the Python SDK: Via pip install MemoryOS install the MemOS Python SDK, and use the interfaces provided by the SDK to easily integrate memory management functionality locally or on a server for rapid development and testing.
• Use MOS: By configuring MOS (Memory Operating System), manage multiple MemCubes to achieve cross-module memory scheduling and unified management, suitable for multi-agent collaboration or complex application architectures.
• Download sample code: Run the memos download_examples command to download the official sample code and configuration files, and refer to the examples to quickly understand and practice MemOS features.
