Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for text-in-image. Use this for posters, Midjourney for art.
