Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier in the agent category. The first one I'd give to a non-technical friend.
