What is Letta?

Letta is an open-source platform designed to build stateful agents that can learn from data and improve with experience. Agents built using Letta have built-in memory, reasoning, auto-persistence in Postgres, and support for over 7000 tools.

The Agent Development Environment (ADE) provides a visual interface for quickly iterating on agent prompts, tools, and model configurations, allowing the visual of agent's memory, reasoning steps, and tool calls to understand their decision making. Letta maximizes agent performance by compiling the most relevant information to pass to the LLM, while keeping token counts under a specified budget.
