A few more clues which are demonstrated, but not explained, by ^this response: * Begins with a slight rewording of your question, rephrased as the introduction to the answer * Ends with at least a sentence or two of CYA-type caveats, like "ultimately it will depend on", "there are many factors", etc. * Writes in full sentences even when not really necessary - eg. this bullet point would be phrased as "Text generated by a language model would be more likely than average to be written in full sentences..." * Avoids pronouns when any ambiguity is present, even if it would be obvious to a human. eg. If the first sentence is: "Robert and Joe were playing football when Joe injured his hand", a human might continue: "He tried to keep playing but it hurt too badly." ChatGPT would be more like: "Joe tried to keep playing but his hand hurt too badly". (this was NOT written by ChatGPT :)
