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 for its niche. Different use case than Suno — SFX and loops, not songs.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
