I can’t exactly put my finger on it, but every god damn thing ChatGPT spits out has the same cadence or structure. Something about how it lays out points and wraps it up, and its usage of commas, is so noticeable to me.
I wouldn’t say it’s necessarily overuse of commas, it’s how it consistently uses them the same way in nearly every response. It’s something about the overall structure of what it spits out. I wish a linguist would pop in and break it down for me. It’s a combination of tone, tense, arrangement of the sentences, how the paragraphs are put together - all of it feels very samey to me, unless it’s prompted otherwise.
There’s only a few “styles” of sentences it spits out and to me, it seems quite obvious. Humans don’t write that consistently all the time, they’re messier.
