Why OpenAI Abandoned Its Own AI Content Detector

Aug 7, 2025

In 2023, OpenAI abandoned its own AI content detector due to its low accuracy rate of only 26%.

“In our evaluations on a ‘challenge set’ of English texts, our classifier correctly identifies 26% of AI-written text (true positives) as “likely AI-written,” while incorrectly labeling human-written text as AI-written 9% of the time (false positives),” they stated.

OpenAI acknowledged years before the curve what is now widely known to be true: post-production AI content detectors are prone to failure.
