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.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.
