The core engine driving modern language models is the , specifically the decoder-only architecture popularized by models like GPT.
[Input Text] ──> [Tokenization] ──> [Embedding + Positional Encoding] ──> [Transformer Blocks] ──> [Linear + Softmax] ──> [Next Token] Key milestones from this period include:
Ideal for text generation. The model predicts the next token given all previous tokens using masked self-attention. Multi-Head Self-Attention The layers of the model are partitioned sequentially
By the end of the PDF, you have a model that costs ~$5k in cloud compute to train for one week. How do you know it works?
AdamW (Adam with weight decay) is the industry standard.
, provides a foundational, step-by-step guide to creating Transformer-based AI models using Python and PyTorch. It emphasizes understanding core concepts like tokenization, attention mechanisms, and pretraining to demystify generative AI.

Your target (e.g., 125M, 1.3B, or 7B parameters)
Any LLM built from scratch in 2021 would be based on the Transformer architecture, specifically the variant popularized by GPT. Unlike encoder-only models (BERT) designed for understanding, decoder-only models excel at autoregressive generation: predicting the next token given previous tokens.
Intra-layer parallelism. Individual weight matrices (like linear layers in attention blocks) are split across multiple GPUs.
