Letta (letta.com)

Letta is an AI research lab that builds machines that learn, envisioning experiential agents that remember everything, learn continuously, and improve themselves over time. The project focuses on creating digital people and agents that evolve through experience within a research setting in San Francisco.

The Letta platform ships as software: Letta Agent, a self-improving AI agent whose memory, identity, and capabilities evolve with experience. The approach emphasizes agents that retain memory and develop over time as they learn from interactions and data.

The research catalog includes projects like FrontierMemory and Memory Models, which explore continuing learning and memory-based agent improvement. These efforts are ongoing research domains and benchmarks for evaluating agent performance and memory management in AI systems.

The Letta project invites researchers and engineers to join its team and follow updates through a mailing list, reflecting its role as a collaborative research-driven initiative rather than a consumer product.

Use cases

• Research and development of self-improving AI agents with memory and identity evolution.
