But why? I routinely see typos and grammar errors on major news articles. LLMs catch that stuff really well, it's like the one thing they're good at. They can be as opinionated as humans on the subject. Perhaps sycophantic mainstream models might be to eager to please, but that's not an issue with the tech itself. I like to think that every publication that is using LLMs to write content has also replaced copyeditors/writers with them.
