Again, these are not "hallucinations" These are the system working as designed and producing a long string of text that plausibly mimics the kind of text requested. The system is not designed to produce factually correct statements and will not, except by coincidence.
KPMG's October 2025 report on the wonders of agentic AI has been accused of demonstrating one of the tech's less desirable talents: making things up.
Research outfit GPTZero claims a forensic review of the Big Four firm's October 2025 report, "Total Experience: Redefining Excellence in the Age of Agentic AI," found that only five of its 45 citations correctly pointed to the cited source; the rest ranged from mangled and misleading to partially fabricated or too vague to verify.

GPTZero dubbed the phenomenon "vibe citing" – the citation equivalent of vibe coding – where generative AI appears to stitch together fragments of real sources, invent titles, or otherwise produce references that look convincing until someone actually clicks them.
GPTZero alleges that roughly half of the report's factual claims were false, unsupported, or attributed to the wrong source. Several case studies highlighting supposedly cutting-edge deployments of agentic AI appear to have been particularly creative.
