Kai's verdictA-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.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.A-tier in its niche. The only one that actually gets emotion right.
