Berkeley Math Professor Stops Grading Homework After Widespread Student Use of AI

His decision reflects faculty struggle to check student work because campus tests found commercial AI-detection tools unreliable and left rules to individual instructors.

Overview

  • Fields medalist Richard Borcherds now awards homework credit for completion rather than grading answers for correctness after observing many students using AI to produce correct solutions.
  • Borcherds told student reporters that pervasive AI use made paying graders to check correctness “no point” and that continued AI progress could leave human mathematicians with little to do.
  • UC Berkeley’s Academic Senate has asked instructors to state course expectations about AI in syllabi and built an AI Hub with sample language for faculty to use.
  • The university tested detection products such as Turnitin and Rumi and judged them insufficiently reliable to standardize campus-wide, so enforcement and specific course rules remain at the instructor level.
  • The change follows OpenAI’s high-profile claim about progress on the Navier–Stokes problem and raises practical and career questions for students, including how departments will assess learning and advise future mathematicians.
