These frameworks hide immense complexity behind elegant APIs, but they also obscure the fundamental mechanics of how these models actually learn. <strong>llm.c</strong> tears away that abstraction, providing a complete, working implementation of GPT-2 training in pure C.</p> <p>Created by Andrej Karpathy (formerly Director of AI at Tesla, co-founder of OpenAI), llm.c is first and foremost an educational project. It implements the entire forward pass, backward pass, and training loop for a transformer language model using nothing but standard C libraries, without a single dependency on PyTorch, TensorFlow, or any machine learning framework.</p>
