Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
