Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
