Andrej Karpathy, a central figure in deep learning and former Director of AI at Tesla, recently made his personal "idea file" public. Rather than a formal academic paper or a software tool, this repository acts as a living wiki for his thoughts on complex technical systems. It’s essentially a public brain dump—a curated, evolving collection of notes, heuristics, and observations that define how a leading researcher makes sense of a rapidly shifting field.

For non-specialists, this is a masterclass in intellectual organization. Instead of digging through hundreds of disjointed papers, we gain insight into the mental models an expert uses to categorize how these systems actually function. Karpathy’s wiki demonstrates that technical expertise isn't just about coding; it’s about synthesis—the ability to connect abstract concepts like context windows, hallucination, and inference patterns into a coherent framework.

By making this file accessible, the resource provides students a blueprint for building their own "second brain." It suggests that in an age of information overload, the most valuable skill might not be memorizing facts, but maintaining a structured, living archive of your own learning journey.
