Use case
GPT-5.4 Pro prepaid credits
prepaid credits 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).
Prepaid credits, not a vendor subscription
Create a console account, add at least $5, and spend it on gpt-5.4-pro. There is no subscription tier. Developers in mainland China use the same path: prepaid USD credits and requests to https://api.corouter.co.
corouter is not affiliated with OpenAI or Anthropic, and it does not promise network reachability. The account, the balance, and the rate card are what the console and this site publish.
The rate for this ID
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.
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.
