Kai's verdictS-tier for speed. When latency is the product, start here.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier infrastructure. The one platform every AI dev eventually uses.
