Is nobody worried that your site might be penalized if your blog uses AI content, or is OP talking only about initial research?
AI generated text is trivial to spot, ironically using also AI, so IMO the AI part should only concern initial research, and for credibility, no matter if towards the reader or a search engine, I'd stick with the same principles you'd be using 10 years ago: mastering a style that grants you a low bounce rate (going to the point, avoiding filler content), adding links to your sources, and even adding links to related posts on your own site.
