Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier for data teams. S-tier if you already live in SQL + Python.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.
