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 carries one pricing dimension, billed by the hour on a c7a.medium instance. The software itself is free, so you pay only for the compute hours you run. Your cost scales with how long you keep the instance running. There are no tiers or add-on options to choose from — usage on this single instance size is the only variable that affects what you pay.
Top-of-mind questions for buyers
You run the software on a single c7a.medium compute instance, billed for each hour it runs. This instance size is fixed for this dimension. The hourly rate covers the software licence; standard AWS compute and storage fees for the instance apply separately.
Software charges accrue only while the c7a.medium instance runs. Stopping the instance halts hourly software billing. A stopped instance may still incur AWS storage fees for its attached volumes, but the software meters running time only.
You run a self-improving AI agent whose memory and capabilities change with use. The agent manages its own context over time. The listed hourly rate applies regardless of how you use these functions on the single instance size.

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.
