Kai's verdict	S-tier for open-source model APIs. The default in this space.	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.	S-tier for aesthetics. If you care how it looks more than how it's made, this wins.	B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
