Model
GPT-5.4 Pro API pricing
Compare the published GPT-5.4 Pro (gpt-5.4-pro) list rate with corouter's outlet rate, and estimate a monthly token bill. 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.
Where this model fits
- Calls that already name gpt-5.4-pro on purpose
- Comparisons against the much lower GPT-5.4 rate
- Vision and reasoning jobs billed at the Pro list rate
Estimates only. Actual billing depends on your real token counts, cache hit rate, and the prices in effect at request time.

- OpenAI vs Anthropic API pricingBoth vendors publish per-million-token rates, but they price context, output, and caching differently enough that the cheaper choice depends entirely on your workload shape.Read the post
