| Kai's verdict | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. | S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing. | S-tier for open-source model APIs. The default in this space. | B-tier. Still early. Manus is more flexible for less money. |
