When Apple launched the Apple Creator Studio (ACS) subscription, the company indicated that you could use the AI features to produce 50 Keynote presentations per month “as a minimum.” However, developer and security researcher Steve Troughton-Smith had a very different experience when it came to AI usage limits.
He reported that far from being able to produce 50 presentations, a single Keynote slideshow used half of his monthly ACS limit, so the limit would be just two …
Troughton-Smith started by saying how impressed he was by Xcode’s Codex support.
So Xcode just builds entire apps without you now. Xcode’s Codex support will happily trundle away for half an hour sticking its tendrils into every little corner of your project, touching and changing every file […] I had Xcode’s new agent feature throw together this little UIKit timeline app, without me writing anything myself, all using Codex […] I’ve used ChatGPT in and out of Xcode a ton, but I’ve never had it just build the entire app for me change by change like you can in Xcode 26.3. I don’t think I wrote one line manually in this timeline app.
He then went on to contrast this with the included AI usage in the Apple Creator Studio subscription.
This entire app used 7% of my weekly Codex usage limit. Compare that to a single (awful) slideshow in Keynote using 47% of my monthly Apple Creator Studio usage limit.
This would mean that creating just two presentations would use up his entire monthly AI usage allocation, not 50. Of course, Apple did use the example of extremely short presentations of just 8-10 slides for its own numbers, but even so, this seems to be a massive disparity.
As John Gruber notes, the contrast between Codex and Apple Creator Studio limits seems the opposite of what we would reasonably expect.
Here’s how to check your current usage status:
