It was published by KPMG, one of the world's 'Big Four' accounting firms.

Junayed graphics/Shutterstock In October last year, KPMG published a report titled Total Experience: Redefining Excellence in the Age of Agentic AI, which was about how companies are using AI to cater to customers' needs. KPMG is one of the "Big Four" professional services and accounting firms in the world, along with Deloitte, Pricewaterhouse Coopers and Ernst & Young. Apparently, though, that report was full of AI hallucinations and included examples of agentic AIs that either did not exist or did not have the capabilities KPMG stated in the paper. Investigators for GPTZero, the maker of an AI content detection tool, found inaccuracies and fake footnotes all over the report, which were also verified by the Financial Times.

In its report of the investigation, GPTZero said that only five citations out of 45 in the paper accurately pointed to real sources. A total of 28 citations paraphrased titles or added fake components to real sources, while 12 were phrased too vaguely to determine whether they actually existed. GPTZero called the creation of fake references by AI models "vibe citing."
