Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for speed. When latency is the product, start here.
