| Kai's verdict | A-tier for real-time. B-tier for everything else. Worth checking when news breaks. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. | A-tier for its niche. Different use case than Suno — SFX and loops, not songs. | S-tier for open-source model APIs. The default in this space. |
