Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-tier for local inference. If you care about privacy or want to tinker, install this today.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
