4o generates new images that try to be close but not exact it doesn't edit existing ones so wouldn't be much use for this.

Valid question, as they already have a partnership with OpenAI to use ChatGPT in Siri. I personally use GPT for illustrations and Nano Banana for photo edits (Midjourney for realistic photos).

As an aside, perhaps they're using GPT/Codex for coding. Did anyone else notice the use of emojis and → in their code?
