Restaurants are increasingly using generative AI to create menu illustrations, which often results in images that appear too perfect, symmetrical, and smooth. This aesthetic can be unsettling to customers, even if they cannot immediately identify why the images seem off. Examples include overly bubbly cheese on burritos or unnaturally round ice cream scoops.
According to Alex Lisle, CTO of Reality Defender, the specific aesthetic of these AI-generated images stems from the way models are built and trained. Large language models and diffusion models learn patterns from vast quantities of data. If the training data is narrow, such as older restaurant menus from a specific era, the AI will replicate that limited style, leading to a lack of diversity and a generic appearance. Lisle noted that many AI-generated menus resemble those from 2015, indicating the source of their training corpus.
A significant concern for AI developers is 'model collapse,' which occurs when AI models are trained on too much of their own AI-generated content. As AI-generated content inevitably seeps into large datasets, there is a risk that models will begin to feed on their own outputs, leading to a degradation of quality and diversity in future generations. This phenomenon is compared to 'mad cow disease' for AI, highlighting the potential for systemic issues in AI development if not addressed.

AI-generated restaurant menus often display an unappetizing, overly perfect aesthetic because the models are trained on limited datasets, leading to a lack of natural variation. This issue, dubbed the "sameness problem," highlights a broader challenge in generative AI where models can produce outputs that feel artificial or incorrect, even if visually flawless.
