Mem0: Universal memory layer for AI agents and LLM applications. Self-improving memory system that personalizes AI interactions and reduces costs.
Mem0 (pronounced 'memo') is a memory layer for AI applications that gives agents and assistants the ability to remember information across conversations. The core idea is simple but powerful: instead of losing context when a conversation ends, Mem0 extracts, stores, and retrieves relevant memories so the AI can personalize interactions over time.
Mem0 works by processing conversation history through an LLM to extract 'memory facts' — discrete pieces of information like user preferences, past decisions, stated goals, or contextual details. These facts are stored as embeddings in a vector database and retrieved based on semantic similarity when relevant to new conversations. The system supports memory at multiple scopes: user-level (personal preferences), session-level (conversation context), and agent-level (learned behaviors).

Open-source Python framework that orchestrates autonomous AI agents collaborating as teams to accomplish complex workflows. Define agents with specific roles and goals, then organize them into crews that execute sequential or parallel tasks. Agents delegate work, share context, and complete multi-step processes like market research, content creation, and data analysis. Supports 100+ LLM providers through LiteLLM integration and includes memory systems for agent learning. Features 48K+ GitHub stars with active community.
