The field of natural language processing (NLP) has witnessed significant advancements in recent years, with the development of large language models (LLMs) being one of the most notable achievements. These models have demonstrated remarkable capabilities in understanding and generating human-like language, revolutionizing applications such as language translation, text summarization, and chatbots. In this article, we will provide a comprehensive guide on building a large language model from scratch, covering the fundamental concepts, architectural design, and implementation details.

Building a large language model from scratch requires a deep understanding of NLP, deep learning, and software development. In this article, we will walk you through the process of designing and implementing a large language model, covering the key concepts, architectures, and techniques.
While the original Transformer placed Layer Normalization after the residual blocks (Post-LN), 2021 architectures universally adopted Pre-LN. Normalizing inputs before they enter the attention and feed-forward layers allows gradients to flow unimpeded through the residual connections, drastically stabilizing deep network training.
