Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for model-shopping. I use this for every prototype before committing.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
