Kai's verdictA-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for local inference. If you care about privacy or want to tinker, install this today.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
