Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.B-tier. Still early. Manus is more flexible for less money.
