AI Now Writes as Many Online Articles as Humans Do (opens in new tab)

We build on our prior research by using 3 different AI detectors (Pangram, GPTZero, Copyleaks). We independently evaluate each to show that the false positive rates and average false negative rates are consistently below 2%. Each AI detector shows a similar trend. While the trend is the same, our previous study estimated the proportion of primarily AI-generated articles to be 3.3 percentage points higher. This relatively small difference is the result of averaging three AI detectors rather than relying on the accuracy of a single detector.
