I myself have never heard it outside of "nerdy" circles... that is: people who would read science fiction. I personally am not entirely happy about the word (no matter how it is spelled) being used for a particular AI product. "Grok" to me means knowing a subject at a much deeper level than I think any AI is capable of at the present level of technology. But it would be passable to use it for a company name, to indicate that it is a goal to strive for.
