Letta Cloud
Deploy stateful agents at scale in the cloud
Letta Cloud is currently in early access. Request early access here.
Letta Cloud is our fully-managed service for deploying stateful agents. While Letta can be self-hosted, Letta Cloud eliminates all infrastructure management, server optimization, and system administration so you can focus entirely on building agents.
The fastest way to bring stateful agents to production
Develop faster with any model and 24/7 agent uptime: Access to OpenAI, Anthropic Claude, and Google Gemini with high rate limits. Our platform automatically scales to meet demand and ensures 24/7 uptime of your agents. Your agents’ state, memory, and conversation history are securely persisted.
Features designed to help you scale to hundreds of agents: Letta Cloud includes features designed for applications managing large numbers of agents: agent templates, template versioning, memory variables injected on agent creation, and advanced tooling for managing thousands of agents across many users.
Model agnostic with zero provider lock-in
Your agent state is stored in a model-agnostic format, allowing you to easily migrate your agents (and their memories, message history, reasoning traces, tool execution traces, etc.) from one model provider to another.
Letta Cloud also supports agent file, which allows you to move your agents freely between self-hosted instances of Letta and Letta Cloud.
You can upload local agents to Cloud by importing their .af files, and run Cloud agents locally by downloading and importing them into your self-hosted server.
