Well, at least it passes the basic sanity test I've been using. ZeroGPT, on the other hand, gives a "100% AI" rating to the introduction and preamble of the US Declaration of Independence (from "When in the Course of human events" to "provide new Guards for their future security").
Yep, it is not able to recognize. To be fair, it's not just dump it into ChatGPT and copy paste kind of AI. We feed it into the model in stages, we use 2-3 different models for content generation, and another 2 later on to smoothen the tone. But, all of these are just OTS models, not trained. For example, we do use Gemini in one of the flows.
