| Kai's verdict | S-tier for open-source model APIs. The default in this space. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. | S-tier inside Photoshop (Generative Fill). B-tier standalone. | A-tier. Niche but beloved. If you've outgrown Notion, try this. |
