Kai's verdictS-tier for local inference. If you care about privacy or want to tinker, install this today.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier in the agent category. The first one I'd give to a non-technical friend.
