Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.S-tier for local inference. If you care about privacy or want to tinker, install this today.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
