Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
