Kai's verdictS-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.B-tier. Useful for first drafts. v0 is the better bet for shipping code.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
