X/Twittervia @karpathy·high signal
A complete GPT implementation (training + inference) in 243 lines — only imports are `os`, `math`, `random`, `argparse`. Karpathy: "This is the *full* algorithmic content. Everything else is just for efficiency. I cannot simplify this any further." A landmark educational artifact that strips the mystique from LLMs.
