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.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
