Kai's verdictS-tier for local inference. If you care about privacy or want to tinker, install this today.B-tier. Still early. Manus is more flexible for less money.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for builders. The right primitives. What Kai is built on under the hood.
