I asked Kagi something about macOS Tahoe, and both the AI answer and the SERP kinda sucked. Tahoe has been around for a month now, and it has been quite widely covered, yet Kagi doesn't really think its macOS at all.
On the screenshot we can see a comparison between Kagi SERP and a google-powered result in Dia (which uses GPT4.1).

I expected the SERP to contain relevant comments from Apple discussion forums, reddit and news articles.
I expected the AI to realize that I'm talking about macOS, and I expected it to dig out concrete steps needed for a fix.
