Kai's verdictS-tier for speed. When latency is the product, start here.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
