Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier for local inference. If you care about privacy or want to tinker, install this today.S-tier for open-source model APIs. The default in this space.
