| Kai's verdict | S-tier for open-source model APIs. The default in this space. | A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google. | S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. |
