Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.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.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
