Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for solo + free. The best free option, hands down.
