I think the downvotes are because people expected you to know Grok is a software LLM where Groq is a hardware scheme on which to run LLMs, or that Groq came out about 7 years before Grok so the "homage" is the reverse, i.e. Elon possibly paying to Groq. Groq was chosen as homage to Heinlein's "Stranger in a Strange Land" which invented the word "Grok" to mean "to understand deeply and intuitively" but also eating a dead loved one ("Resident Alien" on Netflix did that this year). Elon just used the English word directly like "Windows" and "Apple". Not using the word directly like "Groq" makes internet searches easier for everyone.
BTW Heinlein described prompt engineering of an LLM perfectly throughout the opening chapter of his * 1966 * book "The Moon is a Harsh Mistress". The "engineer" even admits he had no hard-core "engineering" training because capitalizing on the new technology didn't need it. The chapter could have been written today.
