How LLMs Work: Tokens, Embeddings, Attention, and Transformers

Follow information through the core stages of a language model

Follow a common autoregressive transformer from text and token IDs through embeddings, causal attention, transformer blocks, and next-token generation. Distinguish training, inference, and retrieval, and learn why plausible output still needs verification.
