Our take: Pick Grok when you want a chat assistant with live web and X search plus image and video generation, and use the same models through an API billed per token.
Main limitation: Consumer plan prices (SuperGrok, SuperGrok Heavy) were not visible in the viewed locale, so what a paid tier costs is unconfirmed.
