Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier. If you're on Vercel/shadcn, this is cheating.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.
