Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier. S-tier if you self-host. The reason open-source image gen matters.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
