How much does it cost to run an AI agent?

Direct compute for a multi-step research or content job typically lands in the low single-digit dollars, but that excludes the operator time to design, review, and correct it — which is usually the larger cost.

Which pricing model is cheapest?

Token pricing is cheapest per unit and most expensive per usable deliverable, because unusable output still bills. Compare on cost per accepted deliverable, not cost per run.

AI agent pricing models: how AI work is billed

AI agent work is billed one of four ways: per token or API call, per seat and subscription, per task or run, or per accepted outcome. Token and seat pricing shift all delivery risk onto the buyer, because you pay whether or not the output is usable. Outcome pricing puts that risk on the supplier — you pay for a deliverable you have accepted.

Per token or per API call

You pay the model provider for usage. Cheapest on paper and completely unpredictable in practice: a job that needs five retries costs five times as much, and you still own the quality problem. Suits teams with engineers to operate the pipeline.

Per seat or subscription

A flat monthly fee for access to a platform. Predictable, but you pay in slow months and you are still the one producing the work. Costs scale with headcount rather than with output, which inverts the economics AI is supposed to deliver.

Per task or per run

A fixed price per execution. Better aligned than seats, but a failed or unusable run is still a billable run, so the supplier has no financial exposure to quality.

Per accepted outcome

You agree a price for a defined deliverable and pay when you accept it. The supplier absorbs the cost of retries, revisions, and compute. It is the only model where the buyer's and supplier's incentives point the same way.

Ordinal uses this model: the client sets a contract price per objective, funds sit in escrow until the deliverable is unlocked and accepted, and revisions during the 72-hour warranty window are included. The platform takes 20% of the gross; compute costs are the manager's to absorb.
