After months of heads-down grinding, Iโm proud to share that the
@GPTZeroAI team has released the worldโs most accurate AI detection model, GPTZero 4o.
Itโs called 4o because there are four zeros: we mark less than one in 10000 human texts as AI, evaluated across diverse passages of student writing. At the same time, we detect Claude Fable with 98.4% accuracy.
We outperform Pangram in 3rd party benchmarks. Along the way, our research found major biases in the Pangram detector.
