Andrej Karpathy demonstrates how to build a character-level language model from scratch using the Transformer architecture. By stripping away production-grade complexity, he reveals the core mechanics of self-attention, residual connections, and layer normalization that power modern systems like ChatGPT.
Key insight: Self-attention is simply a communication mechanism where tokens in a sequence act as nodes in a directed graph, using dot products between 'queries' and 'keys' to determine how much information to aggregate from past tokens.
