Is Grok based on GPT?

I'm curious to know, is Grok, the cryptocurrency platform or technology you're referring to, built upon the foundations of GPT, the popular language model technology? It's a valid question to ask, given the increasing prevalence of AI and machine learning in the finance and cryptocurrency sectors. If Grok does utilize GPT or a similar technology, it could potentially revolutionize the way transactions, predictions, or even decision-making processes are handled within the blockchain ecosystem. However, if Grok is not based on GPT, it's equally important to understand what other innovative technologies it employs to stand out in this highly competitive market. Could you elaborate on the technological backbone of Grok and its relationship, if any, to GPT?
