Kai's verdictS-tier for open-source model APIs. The default in this space.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Useful for first drafts. v0 is the better bet for shipping code.A-tier. Bet on this one — the Sparkpage format is genuinely new.
