Yale Student Suspended and Given F After GPTZero Allegedly Misclassified Exam as AI-Generated

In 2024, Yale University reportedly used GPTZero as one factor in investigating whether Executive MBA student Thierry Rignol used AI on an exam. Rignol reportedly denied cheating and alleged the detector falsely classified his writing as AI-generated. Yale reportedly later suspended him for a year and gave him an F, while citing additional evidence and his conduct during the investigation. Rignol has challenged the process in federal court.
