> Next, they fed existing QR codes into the Stable Diffusion AI image generator and used ControlNet to maintain the QR code's data positioning despite synthesizing an image around it, likely using a written prompt.

A few months ago, after seeing that ChatGPT could produce reasonably accurate MD5 hashes, I tried generating QR codes with a Midjourney prompt. It failed in a really interesting way - it generated _symmetric_ QR codes, even though QR codes are explicitly designed to be asymmetric (think of the timing pattern, the three large blocks). So while I could claim ChatGPT "understood" MD5 hashes, I can't claim that Midjourney "understands" QR codes.

How long until generative models can produce working QR codes on their own?
