For me, the biggest AI writing tell (other than the blatantly obvious ones) is an unnatural consistency in style, whatever style that may be. It's most apparent in longer pieces, and I'm not sure I can really pin down exactly what it is. But human writers seem to lack the ability to keep a 100% consistent voice and lapse into different registers at different times. LLMs don't have this natural rhythm, which makes for an exhausting reading experience.

This comment is really insightful. It is the thing that genuinely flips this. It’s not just the structure, but the robotic voice in my head that autoplays. I had incorrectly assumed everyone felt that was normal. Now let me [completely 180 on my opinion].

Just missing some em-dashes.

That’s also one of its greatest strengths. It’s excellent for taking sloppily written human text and giving it a little polish in voice and consistency. If you use a light touch you can keep it from taking away too much humanity from the original.
But the result is as nice to read as a face filled with filler and botox is to look at.
You get that effect when LLMs write whole sentences or paragraphs. Editing human prose for minor consistency improvements doesn’t do that unless you let it run wild and replace >20% of your text.

Slop is a misapplication issue. Just because today’s models can pump out a lot of text doesn’t mean they’re good for it. And just because letting them run wild produces slop, doesn’t mean they don’t work well for appropriately scoped applications.

My boss always asked me to write in a more neutral style in documents. He doesn't do that anymore.
