I think a site-wide code of conduct update is overdue in any case (older thread), and would be the best place to address this (although reiterating it in the CB-specific rules doesn’t hurt).
I think the “total ban” (option B) is the right choice. Even if marked with a disclaimer, LLM text has an air of unwavering confidence that makes it easy to overlook such a disclaimer. Additionally, a disclaimer does not prevent the text from being picked up by search engines (or even the local site search) and making their results useless.
Some misc points from the lower notes:
- The semantics of the term “LLM” might not be perfect, but it’s certainly better than feeding the popular fiction of these tools being Artificially Intelligent
- I don’t think LLM-assisted writing is an inevitability, or certainly not to the scale some people think it will be. Once the current money-fueled hype wave dies down, more and more people will realize how dangerously incorrect these tools often are.
- Machine-translating text should not fall under these guidelines, it’s clearly a different intent (and people have managed to internalize a decent amount of distrust around something like Google Translates’s output).
