Kai's verdictS-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.A-tier for social/casual. B-tier for serious work. Good entry point.A-tier. S-tier if you self-host. The reason open-source image gen matters.
