How I Self-Hosted a Mem0 Memory Stack (So My AI Agent Remembers)

Описание и применение

Автор создал приватный слой памяти для своего AI‑ассистента, развернув стек Mem0 на Synology NAS. Это позволяет агенту запоминать предпочтения клиентов и историю взаимодействий, не отправляя данные в облако.

Задача

An AI agent that forgets everything between conversations requires a persistent memory layer to retain context across sessions.

Результат

The self-hosted Mem0 stack delivers a private, persistent memory layer that enables the AI agent to remember customer preferences, past interactions, and decisions across sessions, all without data leaving the local network.

Рабочий процесс

• Deploy three Docker containers on the Synology NAS using Portainer compose: mem0 API, LiteLLM gateway, and PostgreSQL 17 with pgvector extension.
• Configure mem0 API with environment variables for OpenAI API key, LiteLLM base URL, MEM0_API_KEY, and PostgreSQL connection string.
• Set up LiteLLM to route fact extraction requests to the chosen LLM (e.g., OpenAI).
• Use POST /memories to add facts, optionally with infer=false for fast verbatim storage.
• Use POST /memories/search to retrieve relevant memories for a user_id and query.
• Inject retrieved facts into the AI agent’s system prompt or context before generating a response.
• Iterate: store new facts, retrieve relevant ones, and use them in subsequent replies.

Доказательства

An AI agent that forgets everything between conversations is a tool you have to reintroduce yourself to every session.

The stack sits in my own PostgreSQL behind my own network, none of that leaves my control.

POST /memories with the default infer=true runs the LLM fact extractor — it classifies and cleans each memory. That's smart but slow, and every call costs a model round-trip.
