Have you... actually used the image recognition features of even something like the web-accessible ChatGPT 4 interface, or are you just guessing here?
I feed it unstructured images of all kinds of things and it generally does a rather good job of describing them.
Just now, I found (what is allegedly) a screenshot of a Facebook ad about microdosing mushrooms. I fed the image to the bot and asked it to identify whether or not it was an ad, and the content of it, and to rate the legality of it on a scale of 1 to 50, with 1 being perfectly legal and 50 being criminally punishable.
It nailed all three questions and gave it a score of 45.
I then did the same thing with a screenshot of a Facebook ad for an Audi Q5, and it nailed all three questions and gave it a score of 1.
I followed this up with some human-made drawing of 4 horses that I found fairly randomly. It also nailed all three questions and gave it a score of 1.
Satisfied with the result, I then stopped. I don't get paid enough to make a study of this. I have little doubt that these results are reproducible.
(And is this an LLM trick or something else? Perhaps a combination of things? Is it AI, LLM, LMNOP, or some kid in a sweatshop overseas? I don't really know -- that distinction is also beyond my pay grade.)
