Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.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.
