Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
