Making machines that learn
We’re solving AI’s memory problem. Create agents that remember everything, learn continuously, and improve themselves over time.
Developer Platform
Give your agents the ability to remember and learn, so they can be more like humans, and less like bots.
AI Research
We are an open AI lab pursuing foundational research in AI memory, continual learning, and self-improvement.
Today's AI agents struggle to remember previous mistakes, and are unable to learn from new experiences. At Letta, we're building machines with real memory that can continually learn and self-improve.
Letta Code: A Memory-First Coding Agent
Introducing Letta Code, a memory-first coding agent. Letta Code is the #1 model-agnostic open source agent on the leading AI coding benchmark Terminal-Bench.
Continual Learning in Token Space
At Letta, we believe that learning in token space is the key to building AI agents that truly improve over time. Our interest in this problem is driven by a simple observation: agents that can carry their memories across model generations will outlast any single foundation model.
