Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for solo + free. The best free option, hands down.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.
