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. S-tier if you self-host. The reason open-source image gen matters.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
