Worked example

$0.5600

Estimated standard-tier token cost for one request. At 10,000 identical requests per month, the token subtotal would be $5,600.00.

Tokenizer profileopenai

Requests above 272,000 input tokens can move into a higher long-context price band.
Cached-token savings depend on provider eligibility and correct cache implementation.
Eligible regional processing endpoints can add 10% to token charges.
Web search is separately priced at $10 per 1,000 calls in the public list-price model.
Taxes, cloud marketplaces, enterprise contracts, retries and quality differences are not included in this example.
