Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier for social/casual. B-tier for serious work. Good entry point.A-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
