Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier for creators training custom looks. B-tier for general use.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for builders. The right primitives. What Kai is built on under the hood.
