| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class. | S-tier for text-in-image. Use this for posters, Midjourney for art. | S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time. |
