Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
