How a Yale AI-cheating dispute became a 13-count federal lawsuit

Yale EMBA student Thierry Rignol has sued the university after being accused of using AI on a final exam.

Yale used GPTZero to flag his answers as possibly AI-generated and imposed a one-year suspension plus an F.

Rignol says the punishment was unjust and has expanded his federal case to 13 claims, while Yale says the discipline was warranted.

The dispute is now testing the reliability of AI-detection tools and university handling of due process, discrimination, and speech-retaliation claims.
