I am sorry to be harsh but I find it amateurish that they would use an AI generated hero image for this and presumably fabricated LLM output -- fabricated by an AI image generator no less

Whenever I create an image like this for the purpose of a demo, I make certain that it demonstrates either real input/output or at least is exemplary of real input/output because the whole point is to instill confidence in the tool. Sure, if the raw outputs aren't clean/comprehensible enough for presenting to stakeholders or others, fine, clean them up to make them comprehensible or add explainers, but there shouldn't be any need to fabricate the inputs.

I feel obligated to respond to the hypothetical "But they don't want to tie it to a particular restaurant or brand" -- you don't have to! Doordash has taken generic food photos for this exact purpose.
