| Kai's verdict | A-tier. S-tier if you self-host. The reason open-source image gen matters. | A-tier for creators training custom looks. B-tier for general use. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | B-tier. Still early. Manus is more flexible for less money. |
