Letta builds an AI operating system for stateful LLM agents with advanced memory management, enabling persistent, self-improving intelligence. Spun out from UC Berkeley's MemGPT project, it serves developers creating agents that remember interactions, adapt over time, and compound improvements without model lock-in. This addresses the core limitation of stateless LLMs by providing infrastructure for long-term learning and evolution.
