| 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 speed. When latency is the product, start here. | A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class. | B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately. |
