THE CLOUD WHERE AI AGENTS LIVE

Launch an agent.
We run it forever.

Yours or ready-made — an assistant for your day or a fleet for your product. Memory, database, compute, durability: built in.

THE CONTRACT

You define three things. Everything else is runtime.

identitywho it is
The base prompt, the model, and its boundaries — including spend budgets, enforced below the model where a clever prompt can't argue.
capabilitieswhat it can touch
Tools. Prebuilt (memory, db, files, shell, ask_human, schedule…) and your own functions — one shape, one registration surface.
skillswhat it knows how to do
A prompt for specific work plus the tools that work may use. Loaded when needed; the agent's hands narrow to the job.
runtimeeverything else
Durable execution, crash-proof sleep and wake, ~$0 idle, metered LLM, the full trace. Built in — never in your code.

There is no llm tool — inference is the loop itself. Read the agent model →
