Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier if you already pay Gemini. B-tier standalone.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
