Professional services giant KPMG has withdrawn a report titled “Redefining excellence in the age of agentic AI” after multiple organizations disputed its claims about their AI practices. Research firm GPTZero uncovered several inaccuracies in the document, which was originally released in October 2025. According to GPTZero, speaking with the Financial Times, these errors likely resulted from AI hallucinations — suggesting that KPMG may have used artificial intelligence to help compose a report about artificial intelligence.

UBS, the UK’s National Health Service, Swiss Federal Railways, and Transport for London each told the FT that the report’s descriptions of their AI usage were either false or misleading. In response, a KPMG spokesperson stated that the firm has removed the report from its websites while it conducts an internal investigation. “We expect all our people to follow our guidelines on the responsible use of AI, including human oversight to validate content and verify independent sources,” the spokesperson added.

This incident follows a similar episode last month, when EY withdrew a report on loyalty rewards programs that was found to contain fabricated footnotes and signs of AI hallucinations.
