the image linked to by the post is the Pangram LLM-detection report of paragraphs in the first screenshot below, reading "100% AI". in lieu of alt text for the screenshots below, I suggest scrolling through @eicker@lemmy.world's profile and https://lemmy.world/comment/26323310, which the screenshots are of. Look at the vote counts.
and for that matter, looking into it, Pangram seems to have an extremely low false-positive rate these days: https://www.theatlantic.com/technology/2026/05/pangram-ai-detection-accuracy/687381/ . the only complaints seem to be about its false negative rate. the FP rate of 1 in 10,000 is maybe higher than you want but whatever of Eicker's text you throw at it it always comes up positive.
