| Kai's verdict | 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. | S-tier for solo + free. The best free option, hands down. | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. |
