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.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
