Letta Agent is a personalized stateful AI agent developed by Letta. It is built on Letta's open-source agent harness and research in memory and continual learning. The agent can preserve information across conversations, acquire reusable skills, and adapt its behavior through continued use.
Uses
The same agent architecture can support coding, research, personal assistance, or longer-running organizational work. Its behavior depends on the memory, skills, instructions, tools, and runtime environment attached to that agent rather than on a single fixed language model.
State and access
Signing in to Letta can back up an agent and make the same state available through the command-line interface, desktop application, web application, connected computers, and supported messaging channels. A local setup can operate without an account, but its state then remains on local disk unless the operator creates a separate backup or synchronization path.
Letta Code is the underlying model-agnostic runtime and developer surface. Letta Agent is the personalized agent experienced through that runtime.
