Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. Genuinely different vibe from Suno — worth trying both for a month.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
