Kai's verdictA-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier for open-source model APIs. The default in this space.
