For example, asking the models to show clocks set to a specific time or people drawing with their left hand. I think most, if not all models, will likely display every clock with the same time...And portray subjects drawing with their right hand.
Thanks for the suggestions. Most of the current prompts are a result of personal images that I wanted to generate - so I'll try to add some "classic GenAI failure modes". Musical instruments such as pianos also used to be a pretty big failure point as well.
I should also add an image that is heavy with "greebles". GenAI usually lacks the fidelity for these kinds of minor details so although it adds them - they tend to fall apart at more than a cursory examination.
