Grok Models
Every Grok language model, explained in plain English. xAI's Grok models — the family behind Grok on X, plus their voice and video siblings.
What are the Grok models?
xAI releases new AI models regularly, and the announcements are usually written for engineers. We explain each model in language anyone can follow: what it does well, what it costs, what it can handle, and how it compares to the one before it.
