How this project is maintained

Around half of the issues opened in the past year never receive a reply. 89% of open issues come from outside the core team, so the backlog reflects real-world use rather than internal planning. Work labelled "status:needs-triage" is answered fastest, typically in under an hour, while "status:needs-design" waits about 5 weeks. Only 6% of issues opened in the past year have been closed. Three people close 56% of everything that gets resolved.

Detailed Description

Memos is a memory management system for large language models and AI agents that provides persistent storage, retrieval, and skill reuse across tasks.

The tool addresses the challenge of maintaining context and knowledge across multiple agent interactions without repeatedly consuming tokens on redundant information. It implements a self-evolving memory architecture that stores information persistently and retrieves it through hybrid methods, allowing agents to build on previous work rather than starting fresh with each task. The system tracks skills and learnings across different interactions, enabling agents to reuse solutions and knowledge patterns they have encountered before.

Developers building multi-turn AI agent systems, particularly those running extended conversations or handling multiple related tasks, should consider this tool if token efficiency matters for their use case. The project explicitly supports integration with DeepSeek Harness and works with various LLM providers including Claude and ChatGPT. It functions as a plugin within broader agentic frameworks and supports the Model Context Protocol for standardized agent communication.

The project shows active development with regular commits addressing core functionality and integration improvements. Work spans memory persistence mechanisms, retrieval optimization, and agent framework compatibility. The codebase receives ongoing refinement to the self-evolving capabilities that allow the system to improve its memory organization over time. Development activity indicates sustained attention to both the underlying memory architecture and the practical integrations needed for real-world agent deployments.
