What the AI agent cost simulator does
An AI agent isn't one API call — it's a loop of them: an orchestrator model planning, worker models doing steps, tool calls, and a context that grows with every turn. This simulator lets you configure that shape (orchestrator + worker models, turns per task, tool calls) and estimates the monthly bill, including the cost that compounds as context accumulates. Free, no sign-up.
How to estimate agent cost
- Pick your orchestrator and worker models.
- Set turns per task, tool calls, and task volume.
- Read the monthly estimate and see how context growth changes it.
Why agents cost more than you expect
The trap is context growth. Because each turn usually re-sends the running conversation and tool outputs, input tokens climb turn over turn, so a 10-turn task can cost far more than 10× a single call. That's why the cheapest single model isn't always the cheapest agent — and why trimming context, capping turns, and routing simple steps to a smaller model matter. To price the underlying models, use the LLM pricing calculator.
