hi @growwithme we actually had the same problem as our community steemitphilippines is currently hosting the steemit challenge. I think in my own honest opinion zero gpt pretty much only relies on the parameters of burstiness and perplexity or maybe they set the detectors too sensitive i also saw some obviously some humanly-made articles which still detected by zero gpt so we have discussion to use this https://openai-openai-detector.hf.space/ detector instead since both zero gpt and gptzero detects even human content, if your sentence have low degree of perplexity and burstiness which would be read as an AI generated content.
