Letta
Independent AI company specializing in AI agents with memory capabilities
About Letta
Letta is a company that provides a memory management platform for building and deploying stateful AI agents. The platform enables developers to create AI agents that can maintain context and memory over long-running conversations, allowing them to learn and evolve from user interactions.
Letta's core technology is based on research from UC Berkeley, including the creators of MemGPT, a system for managing context and memory in AI models. The company offers a fully hosted, model-agnostic API service called Letta Cloud, which allows developers to build and manage their agents at scale. Letta also provides an Agent Development Environment (ADE) with a REST API and SDKs for creating and testing agents locally.
The company's services are aimed at developers and businesses building applications that require sophisticated AI agents with long-term memory and reasoning capabilities. Letta's business model is likely based on a subscription or usage-based fee for its cloud services.
