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.
