Summary

GPT-5.4 Pro is the high-compute variant of GPT-5.4, at $30 per million input tokens and $180 per million output tokens with a 1.05M-token context window. It runs only on the Responses endpoint and single requests can take several minutes.

GPT-5.4 Pro uses more compute per request to produce a more consistent answer. It carries the same $30 / $180 price as the newer GPT-5.5 Pro, but an older knowledge cutoff of 31 August 2025 against 1 December 2025, which makes the newer Pro the better deal on paper.

It accepts text and image input and returns text, with reasoning effort at medium (the default), high or xhigh. Prompts above 272K input tokens are charged at a premium rate and regional processing carries a 10 percent uplift.

No deprecation has been announced.

“unknown” means the figure has not been published, or we have not verified it yet — never that the answer is no. “not published” under the weights licence means this model is not offered with downloadable weights. The price band is ours: it bands the blended price (three parts input to one part output) as budget (≤ $0.50), standard (≤ $3), premium (≤ $12) or flagship.

Lifecycle

OpenAI has not announced a deprecation or shutdown date for this model. That is a statement about what has been published, not a guarantee — providers typically announce a shutdown months ahead, and this page updates when they do.

Use it for

  • Keep an existing GPT-5.4 Pro integration running while you evaluate GPT-5.5 Pro against it.
  • Run offline, high-value reasoning tasks where minutes of latency are acceptable.

Avoid it when

  • You are starting a new integration; GPT-5.5 Pro costs the same $30 / $180 and has a newer knowledge cutoff.
  • You need an interactive response; requests can take several minutes and background mode is recommended.
  • Your integration uses Chat Completions or Batch; only the Responses endpoint is supported.
