Please stop trusting #zeroGpt or other #GPT detectors. The thing with #AI generated text is that it's text and text is just text. There are very limited ways to express anything in text. what you write and what an AI writes use the same language, grammar and letters. AI doesn't leave any metadata or something in the text that these detectors can spot.
The current models do have some sort of pattern that they tend to use in their generations, and these detectors more or less look for these patterns. But the thing is that these patterns are not special at all and literally anyone could unintentionally right like an AI without them knowing. Guess what these tools will say when they see their texts? Happily give a ridiculously high rating of this text being written by AI. That's it. These tools literally just take a guess, and their guess is as good as yours. In fact most the time your guess would be much more educated since you know that person and how likely that they will actually be using an AI or if that is their typical writing style.
People blindly trusting these detectors are affecting the lives of many people in false positives.

Note: I hugely oversimplified how these detectors work, you could search on the internet for more information, but there sophistication doesn't make them more reliable. What I said above still holds true
