Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for designers. The only one that takes vectors seriously.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
