Letta: Open-Source Framework for Stateful LLM Applications

Letta (formerly MemGPT) is an open-source framework for building stateful LLM applications. It enables developers to create agents with advanced reasoning capabilities and transparent long-term memory. The Letta framework is model-agnostic and supports various LLM backends (OpenAI, Anthropic, etc.). Installation is available via Docker and pip. A graphical Agent Development Environment (ADE) simplifies agent creation, deployment, interaction, and observation.
