ChatGPT maker OpenAI comes up with a way to check if text was written by a human

Artificial intelligence research startup OpenAI on Tuesday introduced a tool that’s designed to figure out if text is human-generated or written by a computer.

The release comes two months after OpenAI captured the public’s attention when it introduced ChatGPT, a chatbot that generates text that might seem to have been written by a person in response to a person’s prompt. Following the wave of attention, last week Microsoft announced a multibillion-dollar investment in OpenAI and said it would incorporate the startup’s AI models into its products for consumers and businesses.

Schools were quick to limit ChatGPT’s use over concerns the software could hurt learning. Sam Altman, OpenAI’s CEO, said education has changed in the past after technology such as calculators has emerged, but he also said there could be ways for the company to help teachers spot text written by AI.

OpenAI’s new tool can make mistakes and is a work in progress, company employees Jan Hendrik Kirchner, Lama Ahmad, Scott Aaronson and Jan Leike wrote in a blog post, noting that OpenAI would like feedback on the classifier from parents and teachers.

“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),” the OpenAI employees wrote.

This isn’t the first effort to figure out if text came from a machine. Princeton University student Edward Tian earlier this month announced a tool called GPTZero, noting on the tool’s website that it was made for educators. OpenAI itself issued a detector in 2019 alngside a large language model, or LLM, that’s less sophisticated than what’s at the core of ChatGPT. The new version…
