Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
