Kai's verdictS-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for open-source model APIs. The default in this space.
