Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier. Still early. Manus is more flexible for less money.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
