Kai's verdictA-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.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
