Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier if you already pay Gemini. B-tier standalone.S-tier for open-source model APIs. The default in this space.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
