| Pricing | Pay per second of compute | Included with ChatGPT Pro $200/mo | Free + $10-$20/mo | Free + $12/mo Pro + enterprise |

| Kai's verdict | S-tier for open-source model APIs. The default in this space. | B-tier. Still early. Manus is more flexible for less money. | A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes. | A-tier for its niche. Different use case than Suno — SFX and loops, not songs. |
