College Student Made App That Exposes AI-Written Essays (polygon.com) 48

Posted by msmash from the closer-look dept.
An anonymous reader shares a report: ChatGPT's artificial intelligence generated dialogue has gotten pretty sophisticated -- to the point where it can write convincing sounding essays. So Edward Tian, a computer science student at Princeton, built an app called GPTZero that can "quickly and efficiently" label whether an essay was written by a person or ChatGPT. In a series of recent tweets, Tian provided examples of GPTZero in progress; the app determined John McPhee's New Yorker essay "Frame of Reference" to be written by a person, and a LinkedIn post to be created by a bot. On Twitter, he said he created the app over the holidays, and was motivated by the increasing possibility of AI plagiarism. Further reading:
1. OpenAI is developing a watermark to identify work from its GPT text AI;
2. OpenAI's attempts to watermark AI text hit limits;
3. A metadata 'watermark' could be the solution to ChatGPT plagiarism fears.

The level of knowledge needed for a high school essay isn't that great so as a student you are forced into going describing the subject in excruciating detail stating the obvious to make it look like you did some work. Unfortunately this extends into life after school, where you are forced to read way too much to get basic information.

    • Just to be safe they'll want to run the tool against the essay that they totally wrote all by themselves. If it flags they'll want to tweak it up a bit till it correctly identifies as being totally honest-to-goodness written by them.
      • That will be simple. Just put in a few spelling and grammar errors because the AI is programmed not to do such things.
        • Nor are students if they use regular spelling/grammar checking functionality of the application they use to write the essay. If it would be that easy to fool the AI, yu could just use the AI written essay and change some grammar/spelling.

    Teachers should assume any take-home writing assignment will be influenced by friends, Wikipedia, paid writing centers, etc. This is how writing happens in the real world. Chat Bots are just another tool.

    If you really want to know what a student can do on their own, then sit them with a pencil and a piece of paper in a silent faraday cage for an hour and see what they produce. But that would be pointless, because that's not how anyone in the real world writes.

    The key here is that ChatGPT is closed-source, and that OpenAI has no interest in hiding ChatGPT's authorship.

    That said, even with the above handicaps (i.e. one side isn't even playing the cat-and-mouse game), I suspect the detector could be fooled, just by, for example manually-rewriting a phrase within the text and re-submitting it to ChatGPT for continuation from that point. Or something comparably simple. No way to test it at this point.

    Long-term, there will not be a reliable detector. Any such detector would require detecting statistical regularities that could then be automatically avoided. Without even searching I'm sure somebody has already used generative adversarial networks for this.

      1) A text generator is created.
      2) A tool to check for generated text is created.

      4) ...

      Finally nothing, not even a body of human experts, can distinguish ai- and human-generated text.

      We have had a similar fight between viruses and anti-viruses for a long time. Right now antiviruses are winning because they look at the behaviour of the virus (dynamic analysis) rather than its code (static analysis). But advertisements have blurred the line between "good" and "bad" code so that nobody can really say what is good or bad. The world seems to happily accept such compromise. My browser renders both real Slashdot content and ads all the same, and I don't care.

      I guess the same will happen with text.
      We will just accept that some of it is not real human speech.

If it flags it, regenerate, or change the output enough that it's no longer flagged. Remember, this is a cat/mouse/cat/mouse thing. Make a better forgery detector and you'll just end up with better forgeries.
