Summary

GPT-5.2 Pro is an older high-compute OpenAI model, at $21 per million input tokens and $168 per million output tokens with a 400K-token context window. It runs only on the Responses endpoint, and OpenAI's documentation points to GPT-5.5 Pro instead.

GPT-5.2 Pro is the Pro variant of the GPT-5.2 generation. OpenAI describes it as its previous Pro model and recommends GPT-5.5 Pro, which costs more per token ($30 / $180) but adds a 1.05M-token context window and a newer December 2025 knowledge cutoff.

It accepts text and image input and returns text, with reasoning effort at medium, high or xhigh. Requests can take several minutes, and background mode is recommended to avoid timeouts.

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-5.2 Pro integration running while you evaluate GPT-5.5 Pro against it.
  • Run offline reasoning tasks where minutes of latency are acceptable and the 400K window is enough.

Avoid it when

  • You are starting a new integration; OpenAI's documentation names GPT-5.5 Pro as the current Pro model.
  • You need an interactive response; requests can take several minutes.
  • Your integration uses Chat Completions or Batch; only the Responses endpoint is supported.
  • Cost per call is a constraint; GPT-5.2 itself covers the same ground at $1.75 / $14.
