Andrej Karpathy's comprehensive explanation of Large Language Models (LLMs) like ChatGPT breaks down the entire training process, from data collection and tokenization to the Transformer architecture and next-token prediction. He likens pre-training to extensive reading, supervised fine-tuning to practicing with answer keys, and reinforcement learning to solving problems with unique or subjective answers. Karpathy highlights inherent model flaws, such as the 'Swiss cheese model' of knowledge gaps and the tendency to hallucinate, explaining that LLMs are essentially advanced probabilistic text generators rather than truly understanding entities.
