Best for: Developers and researchers building agents with memory

Visit MemGPT

Letta, the team behind MemGPT, works on agents that keep a lasting memory. Rather than forgetting after each session, its agents are designed to remember past interactions, keep learning and get better the more they are used.

The lab publishes research on memory models and on how agents manage context, including a Git-based approach to agent memory. It is most relevant to developers and researchers who want to build persistent, learning agents.
