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.

Dimensions summary
This listing is free to use, so the software itself carries no license charge. You pay only for the underlying compute through a single hourly dimension tied to the c7a.medium instance. Billing runs per hour that the instance stays running, and your cost scales with how long you keep it active. There are no tiers or add-on options to choose from. The Letta Agent runs as a self-improving AI agent whose memory and capabilities evolve over time.
Top-of-mind questions for buyers
The c7a.medium is a compute-optimized AWS instance type with 1 vCPU and 2 GiB of memory. The software runs on this single instance, and you are billed for each hour it stays active. The Letta Agent runs directly on this machine.
The software carries no license charge, so the listing itself adds no cost. The hourly rate accrues only while the c7a.medium instance runs. A fully stopped instance stops the hourly meter, though AWS may still bill separately for attached storage.
Cost is tied to running time, not to how much the agent does. You pay per hour the c7a.medium instance stays active, regardless of workload volume inside it. To increase capacity, you would run more instances, and each accrues its own hourly charge.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
