Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
