Kai's verdict	S-tier for open-source model APIs. The default in this space.	S-tier for text-in-image. Use this for posters, Midjourney for art.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	A-tier in its niche. The only one that actually gets emotion right.
