With the rise of Artificial Intelligence (AI) and Generative Pretrained Transformer (CPT) text, many teachers are faced with a new challenge. How do we prevent students from using these tools to complete their course work for them? The answer may be to use a tool developed to identify text that has been generated by these GPT tools. Open AI responded to concerns by creating their AI Text Classifier. The tool is very simple to use, simply copy and paste the text into an open text box and click a button. With options that range from very unlikely to likely created by AI, the user can quickly identify content that was generated with GPT.
However, one might ask how accurate are these tools really? I tested out several blog posts from this very blog to see how well the AI Text Classifier would perform at identifying those that I leveraged Open AI's ChatGPT to create. Interestingly, none of my blog posts were identified as having been likely generated using GPT. In fact, of the three posts that leveraged Open AI's ChatGPT, AI Text Classifier two as possibly written with GPT, and was unclear on one of the posts.
Perhaps even more interestingly, when I ran the blog posts through the same tool one post was identified as being very unlikely as having been generated with GPT while the second was also unclear as to whether it was generated using AI. The post listed as being unlikely written with AI was written in a first person format with general instructions on how to create a website using Google Sites. The post where AI Text Classifier was unclear on the source information was written in a more professional voice regarding how guerilla and traditional marketing strategies differ. I would argue that the post that was unclear on whether GPT was leveraged would be written in a similar manner to how students would be expected to write their assignments.
So, are there better tools available to identify GPT generated texts? One suggested option is GPTZero which indicated that parts of both of my completely human written blog posts as potentially containing AI generated text. In addition to the simple statement that the text potentially included AI generated text, it highlighted the specific sentences that triggered this assessment. It did correctly identify the GPT generated blog posts as having likely been entirely generated by GPT. This tool appears to be more on the conservative side of identifying GPT text, but the site does indicate that this should only be one tool for educators and that they should consider the students individually rather than relying solely on their results.
The best tool, in my opinion, is ZeroGPT which not only provides it's analysis as a simple statement but also provides a percentage of the text it believes could be AI/GPT generated. The three posts where I leveraged Open AI's Chat GPT were all correctly identified as being 100% AI/GPT generated. Although, there was editing done to each of these posts.
The manually written blog posts, while not listed as have a 0% chance of containing AI/GPT Generated text, provided the below images as well as highlighted lines to identify where the potentially generated text was in the document. And you could guess from the below images, the first one was the one that also was indicated as being unclear from Open AI's ChatGPT Text Classifier and potentially containing AI generated text by GPTZero. I find the visual provided by ZeroGPT with a possible percentage shows that this is not fool proof tool, it even provides a visual gradient to illustrate this fact.
