Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.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.
