Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
