Impossible prompts:

A black doctor treating a white female patient

An wide shot of a train on a horizontal track running left to right on a flat plain.

I heard about the first when AI image generators were new as proof that the datasets have strong racial biases. I'd assumed a year later updated models were better but, no.

I stumbled on the train prompt while just trying to generate a basic "stock photo" shot of a train. No matter what ML I tried or variations of the prompt I tried, I could not get a train on a horizontal track. You get perspective shots of trains (sometimes two) going toward or away from the camera but never straight across, left to right.

> A black doctor treating a white female patient

4o had no problem with this instruction. [0]

Gemini Pro experimental 2.5 didn't either [1]

> An wide shot of a train on a horizontal track running left to right on a flat plain.

4o could not do this in 3 tries. Each time it was right to left.[0]

Gemini Pro experimental 2.5 missed it as well. [2]

I made 2 more attempts and got it to change the direction: https://chatgpt.com/share/680b4c39-2f1c-8010-b577-b23f63081d...

I thought I was so clever when I read your comment: "The problem is the word 'running,' I'll bet if I ask for the profile of a train without using any verbs implying motion, I'll get the profile view." And damned if the same thing happened to me. Do you know why this is? Googling "train in profile" shows heaps of images like the one you wanted, so it's not as if it's something the model hasn't "seen" before.
