Repeated Edits in ChatGPT Ruin AI Restaurant Menus

Restaurants attempting to cut corners by using generative AI for their menus are running into a visual hurdle known as convergence. When business owners use tools like ChatGPT or Midjourney to design menus and then repeatedly edit them to update prices or item names, the food illustrations degrade. An experiment by an X user named Labtec demonstrated this by editing a ChatGPT-generated menu 100 times, revealing that the food images became progressively smoother, rounder, and more unnatural with each iteration.

This homogenization occurs because large language models and diffusion models are trained on massive datasets to predict what users want. According to Alex Lisle, the chief technology officer of Reality Defender, much of this training data draws from a specific aesthetic, such as "a Chili's menu from 2015." When AI-generated content is fed back into these models, it causes convergence. While less severe than total model collapse, convergence shaves off the unique details of images. Lee Rainie, director of the Imagining the Digital Future Center at Elon University, noted that AI optimization for "pleasingness" ultimately results in extreme homogenization.

For restaurant owners and marketing practitioners, these flawless, symmetrical food images can backfire. Researchers at the University of Duisburg-Essen in Germany discovered that AI-generated food images trigger an "uncanny valley" effect. This psychological response causes consumers to feel more disgust and unease toward almost-real AI food than toward obviously fake illustrations.

To avoid alienating hungry customers, practitioners must realize that AI image generators cannot yet replace professional food styling. Relying on automated tools for repeated menu revisions will only compound the issue, yielding what Lisle described as "Lovecraftian food horrors" rather than appetizing advertisements. In an era where visual authenticity is highly valued, relying on over-smoothed AI graphics may ultimately drive diners away.
