Kai's verdict	S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	S-tier infrastructure. The one platform every AI dev eventually uses.
