MemOS is a memory operating system for LLMs and AI agents, described as providing ultra-persistent memory, hybrid retrieval, and cross-task skill reuse. The repository ships agent configuration files (AGENTS.md, CLAUDE.md, .claude directory) and offers a DeepSeek Harness plugin, with TypeScript source managed via Python tooling (poetry, uv, Make, Docker).

You want a self-evolving memory layer so agents retain context across sessions and tasks while the author reports 35.24% token savings.

Use it to

  • Add persistent long-term memory to LLM applications
  • Reuse skills across agent tasks
  • Reduce token spend via memory-based retrieval
  • Integrate with DeepSeek Harness via the dsh plugin
  • Replace or complement RAG pipelines with hybrid retrieval

For Developers building stateful agents and LLM apps
