Why would you ask this? It sounds like a lead-up to some kind of put down.
> It can produce things it's never seen if only you describe the constituent pieces.
It can produce things it's never seen based on lots of things that it has seen.
> Prompts are a compressed version of the image one wants to create
They emphatically are not. They are instructions to a tool on what relative importance to assign to all of the templates that it was trained on. But it doesn't understand the output image any more than it understood any of the input images. There is no context available to it in the purest sense of the word. It has no emotion to express because it doesn't have emotions in the first place.
> and these days you don't even need "prompts" per se, you can say, make a woman looking towards the viewer, now add a pearl earing, now adjust this and that etc.
That's just a different path to building up the same prompt. It doesn't suddenly cause the AI to use red for a dress because it thinks it is a nice counterpoint to a flower in a different part of the image because it does not think at all.
