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 in its category. The first AI music tool I'd actually listen to.B-tier. Still early. Manus is more flexible for less money.
