Letta (fka MemGPT) is an open source agent development suite with three products, our open source agentic framework, our long-term stateful memory algorithm (and research) and a cloud and local agent development environment UI. We're popular with developers, hosting an active community of 1000+ on our discord and are now focusing on our cloud and onprem support. We have a few live customers behind our cloud, and are looking for engineers to help us scale for a GA and more onprem deployments.
