Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for local inference. If you care about privacy or want to tinker, install this today.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
