Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier for data teams. S-tier if you already live in SQL + Python.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
