Kai's verdictB-tier. Still early. Manus is more flexible for less money.S-tier for open-source model APIs. The default in this space.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for local inference. If you care about privacy or want to tinker, install this today.
