In short
AI agent cost depends on the number of model calls, the paid tools each step uses and how many steps a goal takes. Predictable spending comes from a fixed plan, prepaid credit and limits that stop the agent before it overspends.
What drives cost
- Model calls per step.
- Paid tools such as data lookups or image generation.
- Retries and loops when a step fails.
Common pricing models
- Per-token usage billing.
- Monthly subscription with a run allowance.
- Prepaid credits drawn down per action.
Keep it predictable
- Set a per-action and monthly cap.
- Use prepaid credit instead of open billing.
- Review cost per result weekly.
