Kai's verdictS-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. S-tier if you self-host. The reason open-source image gen matters.
