OpenAI''s GPT-5.4 launch post says GPT-5.4 Thinking is available on chatgpt.com and Android, with iOS "coming soon."

YES if, by May 15, 2026 11:59 PM ET, OpenAI makes GPT-5.4 Thinking available in the official ChatGPT iOS app for at least some regular users.

NO otherwise.

Resolution notes:

  • Internal testing or screenshots without an actual rollout do not count.

  • Enterprise-only admin toggles do count if they are in the iOS app itself and publicly documented.

  • Source hierarchy: official OpenAI product/blog posts, help docs, App Store release notes, or in-app availability confirmed by OpenAI.
