OpenAI scuttles AI-written text detector over ‘low rate of accuracy’

OpenAI has shut down its AI classifier, a tool that claimed to determine the likelihood a text passage was written by another AI. While many used and perhaps unwisely relied on it to catch low-effort cheats, OpenAI has retired it over its widely criticized “low rate of accuracy.”
The theory that AI-generated text has some identifying feature or pattern that can be detected reliably seems intuitive, but so far has not really been borne out in practice. Although some generated text may have an obvious tell, the differences between large language models and the rapidity with which the
