Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
