Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for realtime. If latency matters more than voice catalog, start here.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier inside Photoshop (Generative Fill). B-tier standalone.
