LLMs didn’t randomly invent their own unique style, they learned it from books. This is just how people write when they get slightly more literate than nowadays texting-era kids.
And these suspicions are in vain even if happen to be right this one time. LLMs are champions of copying styles, there is no problem asking one to slap Gen Z slang all over and finish the post with the phrase “I literally can’t! <sad-smiley>”. “Detecting LLMs” doesn’t get you ahead of LLMs, it only gets you ahead of the person using them. Why not appreciate example of concise and on-point self-expression and focus on usefulness of content?
Your point about being able to prompt LLMs to sound different is valid, but I'd argue that it somewhat misses the point (although largely because the point isn't being made precisely). If an LLM-generated blog post was actually crafted with care and intent, it would certainly be possible to make less obvious, but what people are likely actually criticizing is content that's produced in I'll call "default ChatGPT" style that overuses the stylistic elements that get brought up. The extreme density of certain patterns is a signal that the content might have been generated and published without much attention to detail. There's was already a huge amount of content out there even before generating it with LLMs became mainstream, so people will necessarily use heuristics to figure out if something is worth their time. The heuristic "heavy use of default ChatGPT style" is useful if it correlates with the more fundamental issues that the top-level comment of this thread points out, and it's clear that there's a sizable contingent of people who have experienced that this is the case.
But to add a personal comment or criticism, I don't like this style of writing. If you like prompt your AI to write in a better style which is easier on the eyes (and it works) then please, go ahead.
I agree. I wasn't really trying to make a point. But yes, what I am implying is that posts that you can immediately recognize as AI are low effort posts, which are not worth my time.
