Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
