Letta (formerly MemGPT) is an open-source framework for building stateful AI agents with persistent memory, enabling agents that remember past interactions, learn from experience, and maintain consistent personas over long conversations. Unlike stateless chatbots that forget context between sessions, Letta agents maintain structured memory including core identity, conversation history, and learned knowledge, updating their memory intelligently as they interact.
