According to Google, it will only cite sources if it literally copy-paste answers. So sometimes it says, but is rarely because of course it won't just copy-paste everything.
Yeah, I much prefer Bing's sourcing, though I'm less than pleased with it's sources. Bing likes to find a bunch of "Top 10" posts from content farms that answer whatever question I was asking.
I think LLMs still make up most of their answers, but use whatever links they find to generate context for the answers, so there is a lower possibility it'll generate confabulations. Of course, if the source is low-quality, it's just going to use that to justify a sloppy answer.
Still think it's better than me sorting through content farm posts. I look forward to next year's models that are trained on curated data sifting through well-sourced web sites.
*I like to add, "Only use educational or science journalism sources," to get higher quality links.
