| 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 if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for realtime. If latency matters more than voice catalog, start here. |
