| Kai's verdict | A-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. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick. |
