AI detectors are still very very easy to fool, at least as far as text is concerned.
This "100% human" text was straight copy/pasted from ChatGPT. Did not edit it or use the "humanise" option.
Six AI detectors including, hilariously, OpenAI itself, reported this as 100% human.
Only two reported it might be ~50% AI, 50% human.
Again it is 100% written by ChatGPT with zero modifications π
