It was not my best (nor normal) behavior, but the point in this case is that the OP offered very little in his rebuttal. A more contextualized reply would have improved mine as well. I believe actually the person that published this LLM course on GitHub works at ElevenLabs, as Google shows. So the reply could be: "Are you sure? I googled and apparently he works for ElevenLabs". That would have triggered a different reply. So I was not polite enough, and I said sorry, but given the exchange to say "google it" was not terrible, was exactly how I thought I had found it (I google for the wrong name, but citing MLX, plus X, and Google returned the wrong result). So it was a metter of "I did this way".
