Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier in its niche. The only one that actually gets emotion right.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
