Kai's verdictS-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.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
