Kai's verdictS-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 speed. When latency is the product, start here.B-tier. Still early. Manus is more flexible for less money.
