A human can easily produce output that looks like anything an LLM can produce, therefor an LLM detector that can say "this is 100% written by AI" cannot exist. It's really that simple.

The commenter I was replying to claimed exactly this. Their AI detector showed that the text was "100%" AI generated.

I was just expressing some caution. Saying you are 100% certain of anything when the evidence is statistical seems a bit too certain, especially if it was just from a short text sample.

Compare to flipping a coin, counting heads vs tails, and trying to assess if it's a fair or biased coin. After 1000 flips if it's not close to 50/50 you would rightfully be suspect, and if it was 10/90 you should be almost certain it's biased. But you can never be 100% sure.
