As of this morning, the Apple Intelligence integration in Shortcuts for iOS 26 reports it is using GPT-5.

Typing to Siri, however, still reports GPT-4.

It appears Apple has started a gradual rollout for this.

@viticci just out of curiosity, assuming you’re based in the EU, how did you managed to active apple inteligence in our region?
@max9631 @viticci Not sure what you mean, Apple Intelligence is available in the EU
@gliglue @viticci intersting, I should have taken a screenshot, but for czech language it literally said “apple inteligence is not available in your region”. Changing my language tu english US nudged iOS to show “turn on apple inteligence” 🤔 Anyway, thanks for this, otherwise I would have been waiting for godot!
