Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.S-tier for designers. The only one that takes vectors seriously.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for open-source model APIs. The default in this space.
