To build a Large Language Model (LLM) from scratch, you must implement the core Transformer architecture and manage a complete data pipeline : Raw text is broken down into smaller

The first step in building an LLM is curating a dataset. For a scratch build, this might be a collection of public domain books (e.g., Project Gutenberg) or Wikipedia dumps. The quality of the output is directly proportional to the quality and diversity of the input data. For a scratch build, this might be a

Pre-training relies on —predicting the next token given a history of preceding tokens. Optimization & Hyperparameters

You cannot feed raw text into a model. You must use a tokenizer (like Byte-Pair Encoding or WordPiece) to break text into numerical "tokens."
