Letta

The platform for stateful AI agents
README.md

Hello World 👾

Letta Logo

Letta adds state to your LLMs to give them advanced reasoning capabilities and transparent long-term memory. You can use Letta to create powerful LLM agents that can reason about their past interactions, learn from them, and improve their behavior over time.

  • Download the Letta open source framework on GitHub
  • Try the Agent Development Environment (ADE) to build stateful agents in a no-code UI
  • Read the Letta docs to learn about the ADE, Python and TypeScript/Node.js SDKs, Vercel AI SDK integrations and more
  • Join our team and other Letta users and developers on our Discord server

Letta is made with ❤️ by our team in San Francisco (join us!) and over 100 individual contributors from around the world.
