Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.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.
