Tokenizer profileopenai

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