| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier for text-in-image. Use this for posters, Midjourney for art. | S-tier for open-source model APIs. The default in this space. | A-tier for ops automation. B-tier for simple copy (use Claude). |
