The prestigious Michelin Guide has found itself at the center of a controversy following an investigation by American magazine D Magazine. The publication alleges that artificial intelligence may have written most, if not all, of the new reviews of Dallas restaurants featured in the guide’s 2026 edition. Michelin has denied the allegations.
According to the New York Post, suspicions arose after a local chef noticed something unusual about the writing style. Researchers analyzed the reviews using specialized AI-detection software and consulted experts from Carnegie Mellon University.
The Pangram detection system gave the texts a 100% probability of having been generated by AI. University instructors Alex Reinhart and David Brown suggested that GPT-4o may have been used to produce the reviews, identifying the model as a likely author.
The researchers were struck by overly elaborate descriptions, such as the “serene” atmosphere at Mābo and the “carefully curated” ingredients at Sushi Kozy, as well as numerous grammatical oddities. When they compared the texts with earlier Michelin reviews of restaurants in Dallas and other major cities, they found no similar signs of AI use in the other guides they examined.
According to the researchers’ theory, a Michelin inspector may have fed a chatbot brief notes about the restaurants and then edited the resulting text to incorporate personal impressions.
“In some passages, the AI influence is much stronger than in others,” Brown noted. He suggested that the writer may have altered individual sentences after the text was generated.
One sentence from the review of Resident Taqueria particularly puzzled the researchers: “Thoughtful combinations, vibrant flavors, and generous portions reflect the kitchen’s creativity.” They considered it an example of unnatural, content-light writing.
Michelin rejected the allegations. In a statement to D Magazine, representatives of the guide said that all inspector notes published on its website and app are produced collaboratively by a team of experts based on their firsthand dining experiences.
“Artificial intelligence is not used in the writing of these reviews,” the company emphasized.
The controversy raises questions about trust in one of the world’s best-known restaurant rating systems. Michelin inspectors typically assess establishments anonymously, focusing on the quality of the food and consistency of the cooking. Receiving a Michelin star is considered a major achievement for chefs.
“Food writing should be human. There is something deeply human about it. That is why the decision to outsource it to AI seems strange,” the investigation states.
The authors question why a guide that has spent decades building a reputation as a trusted source of restaurant recommendations would need to turn to artificial intelligence to describe the establishments it evaluates.
