For me, working through Karpathy's video series (instead of just "watching" them) helped me tremendously to understand how LLMs work and gave me the confidence to read through more advanced material, if I feel like it. But to be honest, the knowledge I gained through his videos are already enough for me. It's kind of like learning how a CPU works in general and ignoring all the fancy optimization steps that I'm not interested in.

Thanks Andrej for the time and effort you put into your videos.
