Ask HN: GPT 4 Vision can't tell the difference between fonts. Am I asking wrong?

I'm trying to identify whether an image of text has been doctored, sloppily, by using the wrong font.

GPT 4 Vision API suggests that all the fonts in the image are the same "Calibri" font, even when I change one word to an obvious joke font.

Is there an approach or trick for getting GPT 4 to identify that one of the words in an image uses an entirely different font?

Is there a simpler or cheaper approach than using GPT 4?
