Letta Agent is a deeply personalized stateful agent that can learn from experience and improve with use. The Letta Agent harness is fully [open source](https://github.com/letta-ai/letta-code) and builds on our lab’s [latest research](https://www.letta.com/research) in AI memory and continual learning.

You can use Letta Agent to build:
