More context: I sometimes write blog posts that includes content that is, frankly, better for an AI to write (summaries). I don't want to contribute to the AI content apocalypse, and I definitely aim to fact check, edit, and check content for bias. However, is there more I can do? Perhaps ways of demarcating and clearly indicating it's AI generated?
Use the LLM to create the first draft, then rework what it provided you so that you're sure it's correct and it's in your own words.
If you really want to just quote LLM-written text verbatim, do exactly that: as a quote, attributed to the LLM.
