Kai's verdictS-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.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for open-source model APIs. The default in this space.
