Second-Hand Hallucinations: Investigating Perplexity's AI-Generated Sources

Perplexity AI, a generative AI startup building a more accurate artificial intelligence with links to sources, has cemented itself as a serious industry player with a $1 billion valuation and the backing of Jeff Bezos. Perplexity is one of several startups deploying a technique called retrieval augmented generation to resolve AI hallucinations through real-time references to sources on the Internet. In recent months, however, GPTZero has noticed an increased number of sources linked by Perplexi

NYT sued OpenAI for copyright infringement, GPTZero develops tool to detect matches in AI training data

On December 27 2023, The Times sued OpenAI and Microsoft claiming the two companies used its articles to train AI technologies like ChatGPT. NYT claimed that millions of their articles were used to train chatbots, resulting in ChatGPT prompts regurgitating NYT articles word for word. "There is nothing 'transformative' about using The Times's content without payment to create products that substitute for The Times and steal audiences away from it," the Times said and “it’s not fair by any measur

New York Times Investigates Fake AI Biographies on Amazon with GPTZero

“[There’s a] new publishing subgenre: hasty, shoddy, A.I.-generated biographies of people who have just died,” Elizabeth A. Harris, New York Times Journalist said. Upon the death of Joseph Lelyveld this year, former executive editor of the New York Times, his brother was shocked to find, “at least half a dozen biographies were published on Amazon in the days immediately following Lelyveld’s death. Several of them were available for purchase on the same day he died.” The twist - they falsely de

Shifting from Fear to Curiosity — GPTZero conversation with a Catholic School Board Director

Tom D’Amico, the Director of Education at the Ottawa Catholic School Board (OCSB), recently shared on CBC News a balanced approach OCSB is taking to integrating AI with the educational fabric. While we’ve chatted with many schools, we found D’Amico’s approach to be an especially forward-thinking one, and we were thrilled to sit down with him to discuss it. The OCSB, guided by D’Amico, takes an exploratory approach to the potential of AI, rather than a reactionary stance. D’Amico explains a phi

GPTZero at NAACL 2024: Key takeaways and highlights from our talks

Every year, the North American Chapter of the Association for Computational Linguistics (NAACL) conference is one of the most important gatherings in the computational and scientific communities. This year’s conference covered exciting topics like large language models (LLMs) and indigenous languages, LLMs and education, robotics, and neuroscience, to name a few. Alex Adam from our ML team and our advisor Dr. Dongwon Lee spoke at the conference this year. If you missed 2024’s NAACL, here are so

Researchers use GPTZero to investigate the impact of LLMs in peer reviews

In the ever-evolving landscape of academia, the integrity of the peer-review process stands as a pillar of scientific advancement. It’s used by journals and conferences to ensure the validity and significance of research findings and funding institutions to allocate research grants. Peer-reviewed research is prioritized by policy advisory groups, holds special status in the courtroom, and is required for researchers to progress in their academic careers. However, the rapidly growing number of

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

Deep Learning Model Updates

ML Updates: In June, we developed a model that was spades better than any previously released models when evaluated on GPT4 and human data. The updated model combined our previous architecture and statistical discriminators approaches with a traditional deep learning approach that was critical in reducing false negatives for GPT4. After validating the performance of this model on challenging real-world examples, we deployed the model to production. The new model was evaluated both on general,
