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.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.
