Kai's verdictA-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. S-tier if you self-host. The reason open-source image gen matters.
