Letta / MemGPT

by Letta · open-source · Last verified 2026-04-24

Letta (formerly MemGPT) is an agent framework with a novel layered memory architecture. Agents manage their own memory hierarchically across in-context, recall, and archival storage, enabling agents to handle tasks that far exceed the context window of any single LLM call.
