Kai's verdict	A-tier for real-time. B-tier for everything else. Worth checking when news breaks.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	S-tier for open-source model APIs. The default in this space.
