#OpenAI, on their flagship product "Additionally, ChatGPT has no 'knowledge' of what content could be AI-generated. It will sometimes make up responses to questions like 'did you write this [essay]?' or 'could this have been written by AI?' These responses are random and have no basis in fact."
Nominally this refers only to using #ChatGPT as an #AI detector. Extrapolating to other topics is left as an exercise to the reader ¯\_(ツ)_/¯
