Kai's verdictA-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for local inference. If you care about privacy or want to tinker, install this today.
