Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
