How the Best AI Detector Provides Interpretable Scores
TLDR: For a brief summary of this post, please see our support page. Being innovative often requires challenging orthodoxy and thinking from first principles. But what does this process mean in the context of a domain as young as AI text detection? Although the approaches used for detecting AI text are evolving, there is a baked-in assumption in the output of most detectors that a piece of text is either written by a human or an AI, but not both. This false dichotomy makes sense primarily in sc

ESL Bias in AI Detection is an Outdated Narrative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 But this is an outmoded view from out-of-date research.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
