Dashing the hopes of liberal arts professors and teachers, OpenAI decommissions its AI content detector due to poor accuracy.

OpenAI announced the launch of its AI Classifier claiming it could distinguish between text written by a human and an AI. Even then, however, OpenAI called the classifier “not fully reliable,” adding that the evaluations on a “challenge set” of English texts correctly identified 26% of AI-written text as “likely AI-written,” while incorrectly labeling the human-written text as AI-written 9% of the time.
