Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier if you already pay Gemini. B-tier standalone.
