Is OpenAI GPT-5 Pro deprecated?
Yes. GPT-5 Pro is deprecated and OpenAI shuts it down on 2026-12-11 — in ~3 months.
Summary
GPT-5 Pro is deprecated and is retired on 11 December 2026. OpenAI names GPT-5.6 Sol with the pro reasoning mode as its replacement. Until then it runs at $15 per million input tokens and $120 per million output tokens on the Responses endpoint.
OpenAI deprecated gpt-5-pro-2025-10-06 on 11 June 2026 with a shutdown on 11 December 2026. The migration is not a like-for-like model swap: the replacement is GPT-5.6 Sol configured with reasoning.mode set to pro, so the request shape changes as well as the model ID.
It accepts text and image input and returns text, with a 400K-token context window, a 272K max output, a 30 September 2024 knowledge cutoff and support for the high reasoning effort only. It runs on the Responses and Batch endpoints.
Test the replacement early: reasoning mode, latency and output limits all differ from this model.

“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.

- Retired in ~3 months
Use it for
- Keep existing Pro workloads running while you rebuild the request against GPT-5.6 Sol in pro mode.
- Compare answer quality between this model and the replacement before the December 2026 shutdown.
Avoid it when
- You are starting a new integration; this model is retired on 11 December 2026.
- Your prompts depend on facts after September 2024, this model's knowledge cutoff.
- You need Chat Completions; only the Responses and Batch endpoints are supported.

Curated suggestions were picked by a reviewer, with the reason written by hand. Derived suggestions are ranked from the data — shared tags, the same tier and a comparable price band — not from benchmark scores. Check the capability fit yourself: we track lifecycle, price and specifications.
