Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for open-source model APIs. The default in this space.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.
