Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for designers. The only one that takes vectors seriously.S-tier for model-shopping. I use this for every prototype before committing.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
