Firstly, this is HN! If every commenter mentioning Karpathy has to prefix their comment with an intro about Karpathy and LLM, then HN will become a boring read.

Secondly, if you don't know who Karpathy is and what any of this means, it is not all that difficult to search for "Karpathy" and "LLM" in your favorite search engine.
