Letta Agents API is a fully-managed agents API service that transforms stateless LLMs into intelligent, stateful agents with persistent memory. Build production-ready AI applications with self-editing memory, multi-agent systems, and seamless model switching across OpenAI, Anthropic Claude (including through AWS Bedrock), Google Gemini, and Together AI - all through a simple API.
Overview
Letta is the AI operating system that transforms stateless LLMs into powerful stateful agents capable of learning, remembering, and evolving over time. Built on our team's groundbreaking MemGPT and sleep-time compute research, Letta enables developers to create AI agents with self-editing memory that maintain context across conversations, build relationships with users, and continuously improve through experience. Unlike traditional chatbots that forget everything between sessions, Letta agents possess true persistent memory - they remember past interactions, learn from conversations, and develop deeper understanding of users, your organization, and their designated tasks over time.
Highlights
- Stateful agents with infinite memory - Build AI agents that remember every interaction, learn over time, and deliver personalized experiences without context window limitations through Letta's advanced memory management system.
- Zero vendor lock-in with model-agnostic architecture - Switch seamlessly between OpenAI, Anthropic Claude, Google Gemini, or any supported model while preserving your agents' complete state, memories, and conversation history through our portable agent file format.
- Scale to millions of agents instantly - Deploy production-ready AI applications that automatically scale from one to millions of concurrent agents with our fully-managed API service, eliminating all infrastructure complexity and DevOps overhead.
