Advancing the frontier of AI systems with memory

Products

Hosted Cloud

Create, deploy, and manage your agents at scale with Letta Cloud. Build production applications backed by agent microservices with REST APIs.

Letta API

Letta adds memory to your LLM services to give them advanced reasoning capabilities and transparent long-term memory (powered by MemGPT).

Backed by research from

Build AI agents and persist them in a database. Create agent microservices. With Letta’s popular agents framework, powered by MemGPT’s memory management technique, you can create and deploy useful agents that actually last.

Top priority: memory management

We believe that programming agents starts with programming memory. Built by the researchers behind MemGPT, introducing self-managed memory for LLMs.

The future of agent development starts here

Expose the entire sequence of tool calls, reasoning, and decisions that explain agent outputs, right from Letta's Agent Development Environment (ADE).

Build beyond the prototype

Most systems are built on frameworks that stop at prototyping. Letta's Cloud is built by systems engineers for production at scale so the agents you create can increase in utility over time.

The box is white

Interrogate the system, debug your agents, and fine-tune their outputs, all without succumbing to black box services built by Closed AI megacorps.

Our AI systems are model agnostic

Bring-your-own LLMs and RAG system. Pick the model providers that work for your use case, swap them at will. Control is yours.

About the company

Born out of the Sky Computing Lab at UC Berkeley, Letta believes that programming agents starts with programming memory.
