GPT‑5.4 Pro is a chat model associated with AIMLAPI. GPT‑5.4 Pro on this URL is the AIMLAPI route (router), not a claim that AIMLAPI created the weights. AIMLAPI is the recorded vendor. Router and host prices can diverge from the creator's API, and availability can move even when the model name stays the same. The recorded context window is 1,000,000 tokens, with max output around 128,000 tokens. GPT‑5.4 Pro does not have vision, tool use, reasoning, or web access flags turned on in this record. Speed tier: medium. Stored use cases: General.
GPT‑5.4 Pro is listed at $39.00 per million input tokens and $234.00 per million output tokens (USD). That quote is the recorded API rate for this page's provider route, not a subscription seat and not a blended monthly bill. A short prompt and a long agent trace will not cost the same amount even when the sticker price stays put.
No separate access-point rows are stored beyond the AIMLAPI route in the slug. Search the model directory or the API price board before you assume a second host.
How to use this GPT‑5.4 Pro page: read the price as a per-million-token quote, then open the API price directory if you need other providers for the same family. Open a related model page when you are choosing between sizes or between the creator API and a router. Open the product page when the practical question is a consumer subscription (seat, credits, or included models) rather than metered API spend. Status on this record is available.
