Kai's verdictA-tier. Best for teaching a kid to code in 2026.B-tier. Useful for first drafts. v0 is the better bet for shipping code.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
