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 aesthetics. If you care how it looks more than how it's made, this wins.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
