Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for local inference. If you care about privacy or want to tinker, install this today.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
