Letta

Today's AI agents struggle with fragmented context and limited memory. Just as computers needed operating systems to manage resources, your agents need intelligent context management to unlock their full potential. Letta is a complete operating system for building stateful agents AI agents. Letta handles state persistence, context compilation, and intelligent resource allocation, so you can focus on building applications powered by agents that actually learn. Letta was founded by the creators of MemGPT, which introduced memory (or context) management for AI agents. The company was spun out of the UC Berkeley Sky Computing research lab, and is advised by Ion Stoica (co-founder of Databricks, Anyscale) and funded by top-tier investors.
