From PC World: OpenAI has shut down Classifier, its AI tool to detect AI-written work, because of what we discovered at its launch: It stinks.
When OpenAI launched Classifier in January, it was supposed to have been smart enough to detect when a user (say, a student) used ChatGPT or another AI program to author a work. OpenAI pitched Classifier as a way for a teacher to identify if an essay, for example, had been authored by AI instead of as an original work.
But the tool struggled when we tested it, including identifying famous works as AI-authored. Instead of fixing the problems, OpenAI has apparently just shut it down. The Classifier page is blank, and OpenAI added this to the original announcement of the Classifier tool:
“As of July 20, 2023, the AI classifier is no longer available due to its low rate of accuracy. We are working to incorporate feedback and are currently researching more effective provenance techniques for text, and have made a commitment to develop and deploy mechanisms that enable users to understand if audio or visual content is AI-generated.“
