Kai's verdictS-tier for open-source model APIs. The default in this space.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier in the agent category. The first one I'd give to a non-technical friend.
