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.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
