What it does

MemOS provides ultra-persistent memory and token savings for founders using large language models (LLMs) and AI agents, enabling efficient and cost-effective operation of these models.

When to use it
  • When building conversational AI applications that require remembering context across multiple interactions
  • When optimizing LLMs for token usage to reduce costs and improve performance
  • When integrating AI agents into workflows that require persistent memory and skill reuse across tasks
Ready-to-paste prompt
Use the following command to test the MemOS API: `node memos_client.ts -m 'What is the capital of France?'`
Heads up: Make sure to set the `HYBRID_RETRIEVAL` environment variable to enable hybrid-retrieval, which is required for ultra-persistent memory and token savings, by running `export HYBRID_RETRIEVAL=true` before starting the MemOS server
