AI model prices span a seven hundred fifty-fold range, but verification cost determines whether generated output is cheap to use.
Model prices differ sharply, and routing can lower the bill
GPT-5 Nano is priced at $0.05/$0.40 per million tokens, while GPT-5.5 Pro is priced at $30/$180 per million tokens. Those prices put routine and complex model use in very different cost brackets. The gap makes model choice one way to control spending, but the price of producing an answer alone does not establish what the work costs overall.¹
A tiered routing strategy sends routine tasks to cheaper models and complex reasoning to more expensive ones. For AI coding, that approach can cut the bill by 60–80% with minimal quality loss. One listed example puts the saving at 80%: $9.63/day or about $200/month. The saving comes from matching the model to the task rather than sending every task to the same tier.¹
The review determines whether generated work has value The economic value of generated output depends on how cheaply and reliably a competent person can verify it in the real decision.
The review determines whether generated work has value
The economic value of generated output depends on how cheaply and reliably a competent person can verify it in the real decision. That puts review inside the cost calculation: the output has to be checked in the situation where someone acts on it. If a person cannot verify it reliably or efficiently, a low generation price does not establish that the task is inexpensive.²
Cheap output with expensive verification is still expensive work. The distinction is between the price of producing material and the effort needed to establish that it can be used. A low model bill can therefore coexist with a costly process when checking the result takes substantial time or cannot be done reliably.¹²

The number of review steps alone does not show whether the result received an independent check; the reviewer’s access to the underlying case matters too.²
Set the review rules before automating a deliverable
Before automating a deliverable, write down who checks it, how long that check should take and what happens when the check fails. Those decisions make the review process concrete before the output is automated. They also give a team a way to judge the work by its verification requirements, rather than treating the generation price as the complete cost.²
U.S. Census Bureau data from late 2025 through early 2026 put overall business AI use in the 17% to 20% range. That figure describes use across businesses; it does not establish whether a particular task produces value. The relevant test for a deliverable remains whether a competent person can check it cheaply and reliably in the decision where it will be used.²

He wrote about the cost of verifying AI output on July 20, 2026. His practical test is to define the checker, the time allowed and the response to a failed check before automating the work.¹²

Price the Check, Not Just the Output
When you compare AI tools, do not let the per-token price decide for you. The real cost of generated work depends on how cheaply and reliably a competent person can verify it in the actual decision. A low model bill can still mean expensive work if checking the result takes substantial time or cannot be done reliably. Before you adopt a tool, ask what the verification step costs in your own workflow.²
Set your review rules before automating any deliverable. Write down who checks the output, how long that check should take, and what happens when the check fails. Also remember that a second click does not create a second judgment unless the reviewer saw the underlying case on independent terms. Use these criteria to judge whether a task is worth automating, not the generation price alone.²
