AI-generated menus face 'sameness' problem, experts say
This TechCrunch article explores why AI-generated restaurant menus often look unnervingly uniform and unappetizing. Experts explain that AI image generators are trained on a narrow corpus of existing food photography, leading to a homogenized aesthetic, a phenomenon called 'convergence.' Repeatedly editing AI-generated images exacerbates the effect, making food look increasingly smooth and artificial. Researchers at the University of Duisburg-Essen found that nearly-real AI food images trigger an uncanny valley response, causing disgust. The article also touches on model collapse, where AI models degrade when trained on their own outputs, and notes broader implications for trust in visual evidence as AI-generated content becomes more common.
Highlights a growing issue in AI-generated content that could affect marketing and advertising creative, but not a major industry event.

Key Takeaways & Evidence Grounding
- Reality Defender CTO Alex Lisle describes AI menu homogenization as 'convergence,' distinct from full model collapse.
- AI models are trained on vast datasets including existing menus from chains like Chili's, leading to similar styles in outputs.
- A user experiment showed that editing an AI-generated menu 100 times makes food images progressively more round and smooth.
- Researchers at the University of Duisburg-Essen found AI-generated food images elicit an 'uncanny valley' effect, causing discomfort.
- Amazon has been reported to source and destroy rare books to add their content to AI training data.

AI Food Slop Replaces Professional Judgment, Fueling Backlash
This article analyzes the widespread backlash against AI-generated food images flooding social media and restaurant menus. It argues that while fake food photography has long been a practice in advertising, AI has made image generation cheap and effortless, removing the professional judgment of food stylists and art directors. The ‘AI Taste Stack’ illustrates what is lost when the cost of AI generation approaches zero. The core issue is not that AI produces bad images, but that fewer people are involved in deciding what is worth making, leading to a homogenized and often grotesque aesthetic. This trend has implications for brands and advertisers, as they risk alienating consumers with inauthentic and unappealing visuals.
Why AI Images Often Look the Same — How to Fix It
The article explains why many generative AI images appear visually similar and offers practical guidance to produce more distinctive results. Authors Lauren deVane and Michael Stelzner argue the issue often stems from how models are used (open, underspecified prompts and accepting first outputs) and from models' reliance on training-data patterns, which can cause visual homogenization and stereotyping. The piece recommends using concrete reference images, defining a brand's visual language, prompting across seven dimensions (medium, subject, environment, composition, light, aesthetic, intent), iterating across multiple models/tools, and creating reusable prompt templates. It cites a 2025 Scientific Reports study finding Stable Diffusion can produce stereotyped depictions of people. Practical tips include using exact hex color values, character contact sheets, and testing prompts with platforms that run multiple models.
Lieferando halts AI food images after embarrassing failures
Lieferando has paused the use of AI-generated food images on its menus following a series of embarrassing errors. The move comes as the company's parent, Just Eat Takeaway, also struggles with AI-generated visuals, which have produced inaccuracies and even unappetizing depictions. The decision highlights the challenges and risks of deploying generative AI in consumer-facing contexts, where quality control and brand perception are critical. The company will revert to traditional photography and manual curation until the AI technology can be refined to meet quality standards.
