Chasing the Hallucinations: PwC report hallucinates product and government customers

Over the past year, a team of GPTZero investigators has used our Hallucination Check tool to uncover hallucinated citations in government reports, academic papers submitted to prestigious machine learning / artificial intelligence conferences like ICLR and NeurIPS, and research products from three of the big four consulting firms: Deloitte, Ernst & Young, and KPMG. This is the third in a series of investigations into reports containing hallucinated citations surfaced by an automated search pipel

How does GPTZero's Hallucination Check detector work: A technical report

Introduction Hallucinated citations are one of the most frustrating failure modes of Large Language Models (LLMs). While some "vibe citations" are easy for humans to spot, most seem plausible on first glance and require high levels of technical expertise or time-intensive research to identify. Additionally, the production of LLM-generated text (and vibe citations) has scaled explosively since 2022, outstripping the growth of human expertise and research capacity. This disparity has placed an un

Understanding AI Detection Results with Deep Analysis

The GPTZero team is committed to machine learning interpretability as a core aspect of our mission of preserving human value. In a significant step towards this goal, we released our Deep Analysis feature this week for premium users (shown in Figure 1).  Users are able to activate this feature by enabling the Deep Analysis switch on the dashboard when scanning a document. This view provides a novel perspective into how our models reason about a given document to determine whether or not it was

ESL Bias in AI Detection is an Outdated Narrative

Recently, we've seen the resurfacing of a previous narrative on (social) media that AI identification is biased against and failing ESL students. But this is an outmoded view from out-of-date research. In this article, we revisit the original study on ESL bias from Stanford University, and discuss the progress GPTZero has made in mitigating detection bias. Finally we replicate and re-run the original study with the same dataset and parameters outlined by Stanford researchers to demonstrate conc

The Next Generation of Turing Tests

On Friday, September 15, the GPTZero research team ran a human study with more than fifty AI researchers from the University of Toronto Vector AI Institute and affiliate groups. The results were conclusive that even the researchers most familiar with AI language models are unable to discern patterns of AI writing without GPTZero assistance. The study started with members of the GPTZero machine learning team attending the Vector Institute for AI career fair, alongside a variety of companies pitc
