1 . Given the excitement it has created, there’s a good chance that you’ve heard about ChatGPT. It’s a powerful, new artificial intelligence tool, which can do a lot of things such as answering a question, explaining a concept, composing an email or writing a college essay, all in a matter of seconds.
“The essay, in particular the college essay, is dead,” said Edward Tian, a student at Princeton University. “For generations, we have been taught how to research, think, and write. That entire tradition is about to be completely changed.”
Despite having studied AI, Edward, like the rest of us, was so shocked by the power of ChatGPT that he couldn’t shake thoughts about the challenges presented by the AI tool. Then he had an idea. What if he applied what he had learned over the last couple of years to help the public identify whether something has been written by a machine?
On January 2, Edward released his app, GPTZero.
It basically uses ChatGPT against itself. To determine whether an essay is written by ChatGPT, GPTZero uses two indicators: the familiarity of text and the variations of sentences. If the text is very familiar to GPTZero — because ChatGPT has also been trained on such data — then it’s more likely to be AI-generated.
Separately, GPTZero compares the variations of sentences. Humans tend to write with greater varieties, for example, with some longer or complex sentences alongside shorter ones. AI sentences are usually less varified.
Edward isn’t trying to stop ChatGPT in its tracks. He believes that’s impossible, and opposes blanket bans (禁止) against the use of ChatGPT, like the one recently announced by New York City public schools. Students, he believes, will use the technology anyway.
“GPTZero is not meant to be a tool to stop these technologies from being used,” he said. “But with any new technology, we need to be able to use it responsibly and we need to have safeguards.”
