| Kai's verdict | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. | S-tier for open-source model APIs. The default in this space. | S-tier for text-in-image. Use this for posters, Midjourney for art. |
