Kai's verdict	A-tier for real-time. B-tier for everything else. Worth checking when news breaks.	A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.	S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
