Kai's verdictA-tier for social/casual. B-tier for serious work. Good entry point.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. S-tier if you self-host. The reason open-source image gen matters.
