| Kai's verdict | B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately. | A-tier in its niche. The only one that actually gets emotion right. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier for open-source model APIs. The default in this space. |
