GPTZero says it found fabricated sources and false claims in four PwC Middle East reports published between 2024 and 2026, The Decoder reports. One report, “Transforming Governance,” was rated by GPTZero as 84 percent likely to be entirely AI-generated.
The report allegedly promoted a product called Citizen Pulse and claimed governments in Denmark, Saudi Arabia, the United States, and Australia relied on it. GPTZero said it found no evidence supporting those claims.
The company describes the pattern as “vibe citing,” where references may have incorrect titles, URLs, or authors and do not actually support the attached claims. Reports with the highest AI scores also had the most false sources, according to GPTZero.
PwC Middle East told the Financial Times it takes accuracy seriously and is updating a limited number of supporting citations. The issue is broader than one firm: GPTZero has previously reported fabricated sources at other major consultancies, raising questions about review processes for AI-assisted work.
