## Description

Letta is a framework for building, deploying, and managing autonomous AI agents that maintain persistent state across long-term interactions. It provides a comprehensive suite of primitives for defining agents with configurable personas, modular memory blocks, and tool-use capabilities, enabling them to retain user preferences and conversation history over extended sessions.

The platform distinguishes itself through its advanced memory management and orchestration capabilities. It allows agents to autonomously update their own memory, perform retrieval-augmented generation, and coordinate complex multi-agent workflows through hierarchical delegation. By supporting both local and remote execution environments, it enables developers to build stateful agents that can be managed programmatically via API or integrated into existing automation pipelines.

The system includes a robust set of administrative and security features, such as human-in-the-loop approval for tool execution, multi-tenant identity management, and automated performance evaluation suites. These tools allow for the creation of reproducible agent blueprints, version-controlled deployments, and detailed observability into agent reasoning and memory integrity.

The project is distributed as a Python-based framework, providing official SDKs and a command-line interface to facilitate integration into development workflows and production environments.
