Which AI model do I use?

This is a common question I get asked, but models evolve so rapidly that I never felt like I could give an answer that would stay relevant for more than a month or two.

This year, I finally feel like I have a stable set of model choices that consistently give me good results. I’m jotting it down here to share more broadly and to trace how my own choices evolve over time.
