Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.A-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
