Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for text-in-image. Use this for posters, Midjourney for art.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
