Use case

GPT-5.4 Pro pricing

pricing notes for gpt-5.4-pro: the rate card, a worked volume, and when to send this ID. A sample of 1 million input tokens plus 200 thousand output tokens is about $13.20 on corouter (input $6.00, output $7.20).

List rate and outlet rate

GPT-5.4 Pro (gpt-5.4-pro) lists at $30.00 input and $180.00 output per million tokens. corouter bills $6.00 input and $36.00 output. Context is 1.1M.

corouter bills 20% of the published list rate, one fifth of list. Where a cache-read rate exists, it is listed on its own row and discounted the same way.

One volume you can recompute

A sample of 1 million input tokens plus 200 thousand output tokens is about $13.20 on corouter (input $6.00, output $7.20).

GPT-5.4 Pro is the outlier on the rate card: its list output rate is far above GPT-5.4. Send gpt-5.4-pro only when you have already chosen that ID on purpose.
